1. Mineral, seed morphology, and agronomic characteristics of proso millet grown in the inland Pacific Northwest

Author: Tayler Reinman, Jessica Braden, Nathan Daniel Miller, and Kevin M. Murphy

Abstract: Climate change increases stressors that will challenge the resiliency of global agricultural production. Just three crops, wheat, maize, and rice, are estimated to sustain 50% of the caloric demand of the world population, meaning that significant loss of any of these crops would threaten global food security. However, increasing cropping system diversity can create a more resilient food system. One crop that could add diversity to wheat-dominated cropping systems in the inland Pacific Northwest is proso millet, a climate-resilient, small-seeded cereal crop that is highly water efficient, able to grow in low fertility soils, and has a desirable nutritional profile. Proso millet shows potential for adoption in this region due to its short growing season, compatibility with regional equipment, and environmental requirements, however US cultivars have been developed for the Great Plains and little research has been conducted outside of this region. To better understand the potential for adoption in the inland PNW, seven commercially available varieties were planted in a researcher-run trial in Pullman, WA and in a series of producer-run trials across the region in 2022. Samples were analyzed for mineral concentration (Zn, Fe, Cu, Mn, Mg, Ca, P, and K), seed morphology phenotypes (seed area, seed eccentricity, thousand seed weight, and seed color), and agronomic phenotypes (grain yield, plant height, days to heading, days to maturity, and percent emergence). Varieties from the researcher-run trial showed significant differences for all traits excluding percent emergence. Samples from producer-run trials showed differences by location for concentration of all minerals and for all seed morphology traits but were not analyzed for agronomic phenotypes. Samples from producer-run trials showed no difference by variety for mineral concentration but showed varietal differences for all seed morphology phenotypes. Most minerals were positively correlated with one another (0.28

3. Climate data integration into wheat performance evaluation reveals large inter-varietal responses

Author: Joanna Raymond, Steven Penfield, Andrew Lovett, Ian Mackay, Haidee Philpott, Conor John Christopher Simpson, and Stephen Dorling
Subjects: climate change, agroclimate, plant breeding, variety trials, Nutrition. Foods and food supply, TX341-641, Agriculture (General), S1-972
Abstract: There is an urgent need to adapt crop breeding strategies to boost resilience in the face of a growing food demand and a changing climate. Achieving this requires an understanding of how weather and climate variability impacts crop growth and development. Using the United Kingdom (UK) as an example, we evaluate changes in the UK agroclimate and analyse how these have influenced domestic wheat production. Here we quantify spatial and temporal variability and changes in weather and climate across growing seasons over the last four decades (1981–2020). Drawing on variety trial data, we then use statistical modelling to explore the interaction between genotype and agroclimate variation. We show that changes in the UK agroclimate present both risks, and opportunities for wheat growers, depending on location. From 1981–2020, in Wales, the West Midlands, large parts of the North West, and Northern Ireland, there was an overall increase in frost risk in early spring of 0.15 additional frost days per year, whilst in the east early frost risk decreased by up to 0.29 d per year. Meanwhile, over the period 1987–2020, surface incoming shortwave radiation during grainfill increased in the east by up to 13% but decreased in Western areas by up to 15%. We show significant inter-varietal differences in yield responses to growing degree days, heavy rainfall, and the occurrence of late frost. This highlights the importance of evaluating variety-climate interactions in variety trial analyses, and in climate-optimised selection of crops and varieties by growers. This work provides guidance for future research on how climate change is affecting the UK agroclimate and resulting impacts on winter cereal production.

4. Application of AMMI model in zoning of FAO 400-500 maize hybrids

Author: Drašković Bojan, Zečević Veselinka, Hojka Zdravko, Filipović Milomir, Srdić Jelena, Kravić Natalija, and Babić Vojka
Subjects: variety trials, yield stability, zea mays l., Agriculture (General), S1-972, Biotechnology, TP248.13-248.65
Abstract: Identification of high yielding and stable genotypes is one of the main goals in all breeding programmes. Estimation of hybrids is often aggravated due to the presence of genotype x environment (GE) interaction. One of the ways to eliminate negative effect of this interaction is the application of reliable statistical models such as AMMI model, which singles out high yielding and stable genotypes that have positive reaction to the improvement of production environments. This research aimed to establish specific maize hybrids interactions in different environments in two years by AMMI analysis. Twelve KWS maize hybrids belonging to FAO 400-500, were examined in two years over eight locations in Vojvodina. The highest yield in both years had the hybrid KWS2 (12.764 kg ha-1). Based on the AMMI1 model, hybrid KWS9 showed the highest stability and adaptability at all locations. According to AMMI2, hybrids KWS1, KWS3 and KWS12, had the highest stability and adaptability, while hybrids KWS2, KWS6, KWS8, KWS9 and KWS10 showed a satisfactory level of stability and it is necessary to pay attention to which locations they have positive interactions in order to be recommended in such regions. Nevertheless, based on the AMMI2, locations Temerin, Kikinda and Zrenjanin, showed similar interaction response, which points out that the number of trial locations could be reduced. Obtained results would contribute to the more precise decision in hybrids recommendation for the certain region, but also in defining further aims in maize breeding.

5. Landscape Performance, Flowering, and Female Fertility of Eight Trailing Lantana Varieties Grown in Central and Northern Florida

Author: Sandra B. Wilson, Carlee Steppe, Zhanao Deng, Keri Druffel, Gary W. Knox, and Edzard van Santen
Subjects: invasive plants, seed viability, variety trials, Plant culture, SB1-1110
Abstract: Trailing lantana [Lantana montevidensis (Spreng.) Briq.] is a low-growing, woody ornamental valued for its heat and drought tolerance and repeat blooming of purple or white flowers throughout much of the year. In 2011, trailing lantana was predicted to have high invasion risk by the UF-IFAS’s assessment of non-native plants in Florida, and therefore it was no longer recommended for use. All cultivars fall under this designation unless proven otherwise. Eight trailing lantana varieties were obtained from wholesale growers or naturalized populations found in Texas and Australia. Plants were propagated vegetatively, finished in 4-inch pots, and planted in field trials located in central (Balm) and northern (Citra) Florida. Throughout the 24-week study from June to November, mean plant quality was between 4.4 and 4.7 (on a 1 to 5 scale) for U.S. varieties and 3.9 for the Australian form. Mean flowering was between 4.1 and 4.5 (on a 1 to 5 scale) for U.S. trailing lantana varieties and 3.5 for Australian trailing lantana. Australian trailing lantana differed from other U.S. varieties tested, being smaller in size, more sensitive to cold, and having a high female fertility index (producing abundant fruit with viable seed per peduncle). Our findings indicate that some U.S. varieties of trailing lantana are unlikely to present an ecological threat and merit consideration for production and use.

6. Bayesian Hierarchical Models for Measuring Varietal Improvement in Tobacco Yield and Quality.

Author: Ramsey, A. Ford and Rejesus, Roderick M.
Subjects: TOBACCO, CROP quality, ECONOMIC impact
Abstract: We measure the economic impact of varietal improvement and technological change in flue-cured tobacco across quantity (e.g., yield) and quality dimensions under a voluntary quality constraint. Since 1961, flue-cured tobacco breeders in the United States have been subject to the Minimum Standards Program that sets limits on acceptable quality characteristics for commercial tobacco varieties. We implement a Bayesian hierarchical model to measure the contribution of breeding efforts to changes in tobacco yields and quality between 1954 and 2017. The Bayesian model addresses limited data for varieties in the trials and allows easy generation of the necessary parameters of economic interest. [ABSTRACT FROM AUTHOR]

7. Pennsylvania State University Statewide Cultivar Evaluation Program Model.

Author: Sánchez, Elsa S., Butzler, Thomas M., Elkner, Timothy E., Pollock, Robert, and Gioia, Francesco Di
Subjects: VEGETABLE trade, CULTIVARS, SEED industry, FARMERS
Abstract: Cultivar selection is an important managerial task for commercial farmers. Numerous available options provide marketing opportunities for farmers; however, they can also make cultivar selection time-consuming. For the past 13 years, a team of Penn State Extension educators and university faculty has implemented a new model to evaluate cultivars for key vegetable crops to assist farmers. Our approach started by building relationships within the vegetable industry with farmers, seed company representatives, and farmer-driven organizations who support our program with funding and gift-in-kind donations. We also added rigor to cultivar evaluations by conducting trials of key vegetable crops over 2 years at three locations. The results were used to develop cultivar recommendations, which were disseminated through various face-to-face and distance Extension avenues. The results were also published in refereed journals. The combination of funding, Extension products, and refereed articles led to university support. A drawback to our approach was the difficulty implementing uniform production methods at three experimental sites. The input of a statistical consultant assisted with overcoming this drawback. This model also required the use of strategies common to successful teams. Our methods are described here for those who desire to build a similar program. [ABSTRACT FROM AUTHOR]

Abstract: The realization of optimal recommendations for the nutrient balance of upland rice is an excellent strategy to increase the productivity and sustainability of the production system, especially in soils with limiting conditions for cultivation. The objective of the study was to evaluate the behavior of upland rice cultivars (ANa 9005CL, ANa 8001, AN Cambará and BRS A502), by foliar fertilization (MaxiZinc®, Booster® and Broadacre®) in the first year under dryland conditions in Vilhena-RO. The experimental design adopted was a randomized block design (BCT), with four cultivars and two levels of micronutrients and four repetitions, in a 4 × 2 factorial scheme. The production components evaluated showed statistically non-significant means for the foliar fertilizer factor, except for the number of spikes per panicle, for which there was a significant difference with an 8% increase in the cultivar ANA 8001 in relation to the other cultivars evaluated. Although the cultivar BRS A502 had fewer spikelets per panicle, the number of panicles per m2 compensated for this and ensured statistical equality in yield. The cultivar ANa 8001 produced the best results in terms of productivity and physical quality of the grains, under the edaphoclimatic conditions of the region.

11. Colored Sweet Bell and Tapered Pepper Cultivar Evaluation for High Tunnel Production in West-Central Indiana, 2022

Author: Langenhoven, Petrus, Duron Alvarado, Lian Mahorith, and Miranda Oviedo, Eduardo Jose
Subjects: vegetables, capsicum, sweet pepper, variety trials, Agriculture, Horticulture
Abstract: Colored sweet bell-shaped and tapered peppers are a staple at the farmers' market. Many small and medium-sized farming operations in Indiana grow this summer crop. High tunnels allow growers to protect their crops and extend their growing season. Sweet peppers, in particular, benefit from the unique growing environment created by the high tunnel. Planting of peppers can start at least 2-4 weeks earlier in the spring, and production can continue into the fall until the first hard freeze. Pepper variety performance data for Indiana is not readily available. We are working hard to change that. Currently, we have evaluated twenty-five pepper varieties, and each variety is assessed in two production cycles. This paper reports on five sweet bell and five tapered pepper entries.

13. Continuing genetic improvement and biases in genetic gain estimates revealed in historical UK variety trials data.

Author: Raymond, Joanna, Mackay, Ian, Penfield, Steven, Lovett, Andrew, Philpott, Haidee, and Dorling, Stephen
Subjects: *WINTER wheat, *PLANT breeding, *BARLEY, *WHEAT, *SEXUAL cycle, *CROP improvement
Abstract: The current pace of yield increase for major crops is not fast enough to meet future demand. Crop breeding programmes are under increasing pressure to improve existing crops further. Quantifying the contribution of these programmes to observed yield increases is important for evaluating their success and identifying if crop improvement goals are likely to be met. In this paper we explore methods to study the genetic gain of two cereal species, wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.). Specifically, the objective of this research was to identify sources of bias in genetic gain estimates of UK variety trials data. Genetic gain was estimated for fungicide-treated and untreated UK winter wheat, winter barley and spring barley for 1982–2018 using UK National List and Recommended List variety trials data. Subsets of the winter wheat variety trials dataset were used to replicate shorter breeding cycles to quantify the impact of the number and choice of long-term check varieties on estimating genetic gain. While genetic and non-genetic contributions to changes in UK cereal performance are in line with previous estimates, we were able to identify previously undetected changes and biases in estimates of variety performance. Specifically, we observed an increasing yield difference between fungicide treated and untreated variety trials as varieties age, driven by both a breakdown in disease resistance and a previously unobserved long-term increase in yield as varieties age in treated trials. This shows that yields of long-term check varieties cannot be assumed to be stable over time. We found that genetic gain estimates were highly sensitive to the long-term check varieties chosen, whilst the inclusion of multiple checks decreased the standard error of the estimate. The estimation of genetic gain is highly susceptible to bias. We provide recommendations on how to reduce the risk of bias for estimating genetic gain. Accounting for sources of bias in genetic gain calculations is important in any programme of selection to prevent inaccurate quantification of yield progress. • Recent yield plateaus in major crops are reducing the likelihood of meeting future food security. • To direct research investment, accurate quantification of yield progress is required. • The estimation of genetic gain is highly susceptible to bias. • Sources of bias include disease resistance breakdown and instability in long-term variety yields.

14. New Generation of Resistant Sugar Beet Varieties for Advanced Integrated Management of Cercospora Leaf Spot in Central Europe

Author: Johannes Vogel, Christine Kenter, Carsten Holst, and Bernward Märländer
Subjects: Cercospora beticola, sugar beet, variety trials, resistance, breeding progress, sugar beet yield, Plant culture, SB1-1110
Abstract: Cercospora leaf spot (CLS) epidemics in sugar beet have been increasing in recent years causing higher use of fungicides. Concomitantly, the availability of effective fungicides is at risk because of resistance development in the fungus, the lack of new active ingredients as well as restrictive approval practices. A key option for an integrated management of CLS is cultivation of resistant varieties. Because of the yield penalty in resistant varieties, acceptance in commercial practice so far has been low. The aim of our study was to characterize recent sugar beet varieties registered in Germany in terms of resistance and tolerance to CLS and their value for integrated pest management. The genetic basis of CLS resistance in varieties is protected by intellectual property rights even after variety registration and not open to the public due to economic competition. To gain reliable data for cultivation, varieties have to be tested for their resistance traits under field conditions at varying levels of infection with Cercospora beticola. In collaboration with variety related stakeholders, 15 sugar beet varieties were tested in 49 field trials in Germany from 2014 to 2016 for their yield response to CLS. The trials were set up in a split-plot design with and without infection (i.e., with and without fungicide). The classification of varietal reaction to CLS is based on symptomatic leaf area (susceptibility) and the resulting relative yield loss (tolerance). Since the relation between both parameters varied among varieties, it was used as an additional parameter to describe tolerance. On this basis, three groups of varieties were identified. They can be characterized as a susceptible, a resistant and a presumably tolerant cluster. A comparison of the data with an older dataset originating from 2009 to 2011 revealed that yield performance of recent varieties with resistance to C. beticola caught up with susceptible varieties due to breeding progress. They showed no yield penalty in the absence of the disease and better economic performance than susceptible varieties. It is assumed that these varieties will allow a substantial reduction of fungicide use for an advanced integrated pest management under central European conditions.

Abstract: Oilseed rape (Brassica napus) characteristically has high N uptake efficiency and low N utilization efficiency (NUtE, seed yield/shoot N accumulation). Determining the NUtE phenotype of various genotypes in different growth conditions is a way of finding target traits to improve oilseed rape NUtE. The aim of this study was to compare oilseed rape genotypes grown on contrasting N supply rates in pot and field experiments to investigate the genotypic variations of NUtE and to identify indicators of N efficient genotypes. For 50 oilseed rape genotypes, NUtE, dry matter and N partitioning, morphological characteristics, and the yield components were investigated under high and low N supplies in a greenhouse pot experiment and a field trial. Although the genotype rankings of NUtE were different between the pot experiment and the field trial, some genotypes performed consistently in both two environments. N-responder, N-nonresponder, N-efficient and N-inefficient genotypes were identified from these genotypes with consistent NUtE. The correlations between the pot experiment and the field trial in NUtE were only 0.34 at high N supplies and no significant correlations were found at low N supplies. However, Pearson coefficient correlation (r) and principal component analysis showed NUtE had similar genetic correlations with other traits across the pot and field experiment. Among the yield components, only seeds per silique showed strong and positive correlations with NUtE under varying N supply in both experiments (r = 0.47**; 0.49**; 0.47**; 0.54**). At high and low N supply, NUtE was positively correlated with seed yield (r = 0.45**; 0.53**; 0.39**; 0.87**), nitrogen harvest index (NHI, r = 0.68**; 0.82**; 0.99**; 0.89**), and harvest index (HI, r = 0.79**; 0.83**; 0.90**; 0.78**) and negatively correlated with biomass distribution to stem and leaf (r = −0.34**; −0.45**; −0.37**; 0.62**), all aboveground plant section N concentration (r from −0.30* to −0.80**), N distribution to the vegetative parts (silique husk, stem and leaf) (r from −0.40** to −0.83**). N-efficient (N-responder) genotypes produced more seeds per silique and had significantly higher NHI and HI than did N-inefficient (N-nonresponder) genotypes. In conclusion, across the pot and field experiments, the 50 genotypes had similar underlying traits correlated with NUtE and seeds per silique may be a good indicator of NUtE.

Abstract: En el cultivo de soja, la selección de la variedad a utilizar, es una de las prácticas de manejo que definen la estructura del cultivo que, en un determinado ambiente, le permitirá explorar recursos para lograr un rendimiento alcanzable. Esta interacción exige la adecuada caracterización del ambiente de manera previa y un acertado conocimiento de las variedades disponibles a utilizar en el mismo. Cada campaña se ve caracterizada por la ocurrencia y la distribución de las precipitaciones. Es bueno tener en cuenta que productores y técnicos cuentan con información sobre el comportamiento de cada lote con los cultivares utilizados en diferentes campañas, que reflejan y describen el sistema de características ambientales locales. El análisis de esta información es relevante para orientar la elección de grupo de madurez (GM) o la incorporación de nuevos cultivares (teniendo en cuenta longitud del ciclo, hábito de crecimiento, potencial de rendimiento, comportamiento a vuelco, enfermedades y plagas, etc.) y las prácticas de manejo asociadas. Para conocer mejor, y generar información validada, el INTA, en convenio de vinculación y asistencia técnica con la Asociación de Semilleros Argentinos (ASA) evalúan anualmente los cultivares comerciales de soja. Para ello, se conducen ensayos experimentales divididos GM en 13 sub-regiones de diferentes zonas del país. En los mismos se evalúa el rendimiento en grano, las características agronómicas, el comportamiento sanitario y la calidad industrial de una gran cantidad de cultivares comerciales disponibles, para elaborar recomendaciones sobre elección y manejo basadas en la productividad, la estabilidad y adaptabilidad de las variedades en cada sub-región de cultivo. Dentro del plan de siembra que incluye 65 localidades, este artículo se referencia en los ensayos de Red Nacional de Evaluación de Cultivares de Soja (RECSO) llevados a cabo en Plá (Alberti), conducidos por la Agencia de Extensión Rural Bragado del INTA. Fueron realizados en lotes del Criadero Klein, empresa que además colabora prestando la maquinaria y pone a disposición personal y los insumos requeridos para la correcta conducción de los ensayos.

Abstract: The processing yield or performance, which includes drying and depulping of coffee fruits, can be calculated as the relationship between the volume of ripe coffee fruits and green coffee weight and is a relevant characteristic for the development of new cultivars. The purpose of this study was to evaluate the processing performance of 42 genotypes and one population of Coffea canephora. The treatments consisted of 42 C. canephora genotypes propagated by cuttings and one seed-derived population arranged in a randomized block design with three replications. The genotypes were harvested when 80% of the fruits were in the ripe stage (red berries). We evaluated the relationship of the volume to weight of ripe fruit (ripe fruit volume [RFV]/ripe fruit weight [RFW]), the percentage of seed per fruit (% of seeds), the yield (in liters of ripe coffee) required to produce a 60-kg bag of green coffee, and the relationship between RFW and dry green bean weight (RFW/dry seed weight [DSW]). The results were subjected to ANOVA, and the means were grouped by the Scott-Knott test (p < .05). The mean yield of the evaluated genotypes was 347.57 L bag-1 of green coffee (between 294.01 and 439.72 L bag-1). A lower seed per fruit percentage identifies genotypes with a lower yield and higher RFW/DSW ratio. The genotypes Z21, 700, AD1, LB1, Emcapa 143, and AP required less than 315 L of ripe coffee to produce one 60-kg bag of green coffee beans. Made available in DSpace on 2021-03-23T03:33:51Z (GMT).

Abstract: En el NO del Chubut se utilizan insumos extraregionales para la recría y terminación de animales con una alta incidencia del flete en el costo de los mismos. Es por esto que resulta de vital importancia evaluar alternativas de forrajes de alta calidad que reemplacen dichos insumos, como por ejemplo arveja forrajera. En la zona centro-norte del país, el cultivo de arveja constituye una excelente alternativa como cultivo invernal, por su corto ciclo de crecimiento. Se siembra en julio y se cosecha a fines de octubre o principios de noviembre. A diferencia de los demás granos utilizados en alimentación animal, la arveja presenta elevados niveles de proteína (18 al 22%) y Lisina, y aunque es baja en Metionina, tiene poca cantidad de factores anti nutricionales. Sus valores energéticos son similares al grano de maíz, lo que constituye una interesante opción en la alimentación animal. En este sentido, podría reemplazarlo como ingrediente en una dieta, tanto por su aporte energético como por el componente proteico de la ración (núcleo, expeller, urea u otros). Con el fin de generar información local respecto a los rendimientos que se pueden lograr de la arveja (Pisum sativum, L) bajo condiciones de riego, se realizó el ensayo en el Campo Agroforestal Experimental INTA Esquel.

24. Ensayo comparativo de rendimiento de cultivares de cebada cervecera bajo riego en el Valle 16 de Octubre: temporadas (2020 y 2021)

Author: Lexow, Guillermo and Bobadilla, Segundo Evaristo
Subjects: Ensayos de Variedades, Malting Barley, Región Patagónica, Cebada Cervecera, Variety Trials
Abstract: La producción de cereales en el Noroeste de Chubut se concentra fundamentalmente en el Valle 16 de Octubre, debido a que es el más extenso con más de 17000 ha, de las cuales 8.000 tienen superficie arable. De los cereales se destaca la cebada, donde anualmente se cultivan alrededor de 500 ha. Tradicionalmente se destina el grano de cebada para alimentación animal. Por otro lado, la producción de cerveza artesanal ha cobrado gran importancia en los últimos años, especialmente en la Patagonia, en donde se concentran 40% de las cervecerías artesanales del país, las que producen aproximadamente el 24% del volumen del país. Estas producciones se abastecen de maltas producidas a gran escala en la región pampeana, esencialmente a partir de variedades extranjeras. Si bien la producción zonal de malta es incipiente e insuficiente, (denotando la falta de plantas de malteo que presentan alta inversión inicial), existiría una potencial demanda de malta de producción local, en función del agregado de valor y un menor costo de flete. El objetivo del trabajo fue evaluar el rendimiento de distintos genotipos comerciales y líneas experimentales de cebada de dos hileras (cerveceras) en el campo experimental de INTA Esquel ubicado en Aldea Escolar.

28. New Generation of Resistant Sugar Beet Varieties for Advanced Integrated Management of Cercospora Leaf Spot in Central Europe.

Author: Vogel, Johannes, Kenter, Christine, Holst, Carsten, and Märländer, Bernward
Subjects: CULTIVARS, SUGAR beets, CERCOSPORA diseases of plants
Abstract: Cercospora leaf spot (CLS) epidemics in sugar beet have been increasing in recent years causing higher use of fungicides. Concomitantly, the availability of effective fungicides is at risk because of resistance development in the fungus, the lack of new active ingredients as well as restrictive approval practices. A key option for an integrated management of CLS is cultivation of resistant varieties. Because of the yield penalty in resistant varieties, acceptance in commercial practice so far has been low. The aim of our study was to characterize recent sugar beet varieties registered in Germany in terms of resistance and tolerance to CLS and their value for integrated pest management. The genetic basis of CLS resistance in varieties is protected by intellectual property rights even after variety registration and not open to the public due to economic competition. To gain reliable data for cultivation, varieties have to be tested for their resistance traits under field conditions at varying levels of infection with Cercospora beticola. In collaboration with variety related stakeholders, 15 sugar beet varieties were tested in 49 field trials in Germany from 2014 to 2016 for their yield response to CLS. The trials were set up in a split-plot design with and without infection (i.e., with and without fungicide). The classification of varietal reaction to CLS is based on symptomatic leaf area (susceptibility) and the resulting relative yield loss (tolerance). Since the relation between both parameters varied among varieties, it was used as an additional parameter to describe tolerance. On this basis, three groups of varieties were identified. They can be characterized as a susceptible, a resistant and a presumably tolerant cluster. A comparison of the data with an older dataset originating from 2009 to 2011 revealed that yield performance of recent varieties with resistance to C. beticola caught up with susceptible varieties due to breeding progress. They showed no yield penalty in the absence of the disease and better economic performance than susceptible varieties. It is assumed that these varieties will allow a substantial reduction of fungicide use for an advanced integrated pest management under central European conditions. [ABSTRACT FROM AUTHOR]

29. Tomato variety trials for productivity and quality in organic hoop house versus open field management.

Author: Healy, G.K., Emerson, B.J., and Dawson, J.C.
Subjects: AGRICULTURAL productivity, TOMATO varieties, TOMATOES, FOOD quality
Abstract: Tomatoes are a profitable direct-market crop for diversified Midwestern farmers. Unfortunately, many tomatoes with the flavor and quality characteristics consumers desire (such as heirloom varieties) lack agronomic traits important to organic farmers. Hoop-house production offers potentially higher yields and quality than field-grown tomatoes, and has become a popular option for organic farmers. This study compares 19 varieties of tomatoes in both organic hoop house and field conditions, to identify high-performing varieties for future plant breeding, and to characterize the effect of hoop houses on productivity and quality traits. We found that tomatoes grown in a hoop house had significantly higher yield, lower disease severity and higher °Brix (soluble sugars) than those grown in an adjacent field; and that management (hoop house versus field) had significantly more influence over those traits than other variables (variety, market class or year). This lack of varietal differences between management systems will simplify breeding efforts aimed at introducing varieties for hoop house production. [ABSTRACT FROM AUTHOR]

Abstract: Identification of high yielding and stable genotypes is one of the main goals in all breeding programmes Estimation of hybrids is often aggravated due to the presence of genotype x envi- ronment (GE) interaction One of the ways to eliminate negative effect of this interaction is the application of reliable statistical models such as AMMI model, which singles out high yielding and stable genotypes that have positive reaction to the improvement of production environments This research aimed to establish specific maize hybrids interactions in different environments in two years by AMMI analysis Twelve KWS maize hybrids belonging to FAO 400-500, were exam- ined in two years over eight locations in Vojvodina The highest yield in both years had the hybrid KWS2 (12 764 kg ha-1) Based on the AMMI1 model, hybrid KWS9 showed the highest stability and adaptability at all locations According to AMMI2, hybrids KWS1, KWS3 and KWS12, had the highest stability and adaptability, while hybrids KWS2, KWS6, KWS8, KWS9 and KWS10 showed a satisfactory level of stability and it is necessary to pay attention to which locations they have positive interactions in order to be recommended in such regions Nevertheless, based on the AMMI2, locations Temerin, Kikinda and Zrenjanin, showed similar interaction response, which points out that the number of trial locations could be reduced Obtained results would contribute to the more precise decision in hybrids recommendation for the certain region, but also in defining further aims in maize breeding. Identifikacija visoko prinosnih i stabilnih genotipova jedan je od vodećih ciljeva u svim ople- menjivačkim programima Pravilna procena hibrida je često veoma otežana usled prisustva in- terakcije genotip/spoljašnja sredina Jedan od načina da se eliminišu negativne posledice interak- cije je da se primenom pouzdanih statističkih modela, kao što je AMMI model, izdvoje stabilni, visoko prinosni genotipovi, koji pozitivo reaguju na poboljšanje uslova u kojima se gaje Cilj ovog rada bio je da se metodom AMMI analize pronađu i utvrde specifične interakcije hibrida kukuruza u različitim sredinama u dve godine istraživanja Odabrano je 12 KWS hibrida kuku- ruza FAO 400-500, koji su ispitivani u dve godine na šest lokaliteta u Vojvodini Najveći prinos u obe godine ispitivanja imao je hibrid KWS2 (12 764 kg ha-1) Na osnovu AMMI1 modela hibrid KWS9 je pokazao najveću stabilnost i adaptabilnost na svim lokacijama Analizom AMMI2 bi- plota utvrđeno je da hibridi KWS1, KWS3 i KWS12 pokazuju najveću stabilnost i adaptabilnost, dok hibridi KWS2, KWS6, KWS8, KWS9 i KWS10 pokazuju zadovoljavajući nivo stabilnosti i potrebno je obratiti pažnju sa kojim lokacijama ostvaruju pozitivne interakcije i u tim regionima ih preporučivati Takođe na osnovu AMMI2 biplota, lokacije Temerin, Kikinda i Zrenjanin su pokazale vrlo sličan interakcijski odgovor, što ukazuje na mogućnost smanjenja broja lokacija za izvođenje ogleda Rezultati dobijeni ovim istraživanjem će doprineti preciznijem i kvalitetnijem odlučivanju prilikom izbora hibrida koji će se gajiti u određenom regionu, ali i definisanju daljih pravaca u oplemenjivanju kukuruza.

Abstract: Trailing lantana [Lantana montevidensis (Spreng.) Briq.] is a low-growing, woody ornamental valued for its heat and drought tolerance and repeat blooming of purple or white flowers throughout much of the year. In 2011, trailing lantana was predicted to have high invasion risk by the UF-IFAS’s assessment of non-native plants in Florida, and therefore it was no longer recommended for use. All cultivars fall under this designation unless proven otherwise. Eight trailing lantana varieties were obtained from wholesale growers or naturalized populations found in Texas and Australia. Plants were propagated vegetatively, finished in 4-inch pots, and planted in field trials located in central (Balm) and northern (Citra) Florida. Throughout the 24-week study from June to November, mean plant quality was between 4.4 and 4.7 (on a 1 to 5 scale) for U.S. varieties and 3.9 for the Australian form. Mean flowering was between 4.1 and 4.5 (on a 1 to 5 scale) for U.S. trailing lantana varieties and 3.5 for Australian trailing lantana. Australian trailing lantana differed from other U.S. varieties tested, being smaller in size, more sensitive to cold, and having a high female fertility index (producing abundant fruit with viable seed per peduncle). Our findings indicate that some U.S. varieties of trailing lantana are unlikely to present an ecological threat and merit consideration for production and use.

Abstract: El manejo de las enfermedades en el cultivo de colza se basa principalmente en el empleo de cultivares resistentes o de buen comportamiento. En la EEA Paraná del INTA, desde el año 2013, se realiza la evaluación de enfermedades en cultivares (de polinización libre e híbridos) y líneas experimentales. La información que se obtiene constituye una herramienta más que disponen productores y asesores técnicos al momento de decidir la adecuada elección del cultivar y la planificación bajo diferentes condiciones. Con la finalidad de determinar el comportamiento a diferentes enfermedades de 13 materiales de colza de tipo primaveral (Tabla 1), se realizaron observaciones en un ensayo de evaluación de cultivares y líneas experimentales de colza (Coll, 2022), implantado el 28/04/21 sobre un suelo Argiudol ácuico, serie Tezanos Pinto. El cultivo antecesor fue soja (Glycine max) y el lote contaba con una secuencia de cultivos sin brasicáceas por más de 4 años. Las parcelas consistieron en seis surcos de 8,5 m de longitud distanciados a 0,22 m (superficie de 11,2 m2), distribuidas al azar en tres bloques. Los diferentes estados fenológicos se determinaron de acuerdo a la escala BBCH. EEA Paraná Fil: Velazquez, Pablo Daniel. Instituto Nacional de Tecnología Agropecuaria (INTA).

Abstract: Cultivar selection is an important managerial task for commercial farmers. Numerous available options provide marketing opportunities for farmers, however, they can also make cultivar selection time-consuming. For the past 13 years, a team of Penn State Extension educators and university faculty has implemented a new model to evaluate cultivars for key vegetable crops to assist farmers. Our approach started by building relationships within the vegetable industry with farmers, seed company representatives, and farmer-driven organizations who support our program with funding and gift-in-kind donations. We also added rigor to cultivar evaluations by conducting trials of key vegetable crops over 2 years at three locations. The results were used to develop cultivar recommendations, which were disseminated through various face-to-face and distance Extension avenues. The results were also published in refereed journals. The combination of funding, Extension products, and refereed articles led to university support. A drawback to our approach was the difficulty implementing uniform production methods at three experimental sites. The input of a statistical consultant assisted with overcoming this drawback. This model also required the use of strategies common to successful teams. Our methods are described here for those who desire to build a similar program.

Abstract: Durante la década de los ´90, al tener lugar transformaciones importantes en los sistemas de producción (labranzas, rotación, fertilización), se planteó la necesidad de evaluar los efectos acumulados de esos cambios en el tiempo. Para ello se implementaron 3 estrategias: a) evaluar situaciones que ya habían iniciado estos cambios, muestreando lotes de productores de distintas texturas y prácticas de uso; b) seguimiento de lotes de productores caracterizando la secuencia de cultivos y los efectos que van teniendo lugar sobre distintas propiedades de los suelos y c) establecer módulos experimentales de larga duración donde se contrasten tratamientos que permitan ir monitoreando sus efectos en el tiempo. El primer capítulo, resume parte de la historia y carisma fundacional de quienes fueron “vértebras” en el desarrollo de instituciones como CREA e INTA, principales impulsores de los estudios de larga duración. Presentamos allí parte del “camino transitado” para la puesta en común de prioridades de experimentación buscando respuestas a problemáticas emergentes de los sistemas de producción. Los ensayos de larga duración, fueron priorizados porque constituyen herramientas valiosas para estudiar y entender procesos, mecanismos y sistemas complejos que se expresan en el mediano a largo plazo; permiten generar información básica y aplicada; permiten calibrar y validar modelos de simulación; y dan lugar a la posibilidad de trabajo con enfoque de sistema y a las interacciones inter e intradisciplinarias e institucionales. Los mismos han sido estratégicos en la capacitación y formación de recursos humanos. La presente publicación contiene 12 capítulos con resultados de una serie de ensayos de larga duración, que fueron conducidos durante los últimos 35 años. EEA Anguil Fil: Quiroga, Alberto.

Abstract: Root-knot disease is among the main diseases affecting coffee crop. The plant selection to the development new resistant cultivars is among one the most efficient methods of control. The present work aimed to quantify the resistance responses of Coffea canephora clones to root-knot nematode Meloidogyne incognita in the Western Amazon. For this, 17 previously selected clones were evaluated in three experimental trials, carried out in the municipalities of Ji-Paraná and Porto Velho, Rondônia. The resistance to root-knot nematodes M. incognita were evaluated by the numbers of gall in the roots (NG) and by the reproductive factor (RF). The resistance response was also interpreted according the genetic diversity of the clones based in their morphological traits. The clones BRS3210, C12, BRS2314, BRS3137 and BRS1216 are resistant to M. incognita with RF of 0.34, 0.62, 0.79, 0.86 and 0.98, respectively. BRS3213, C125, C15, BRS2336, BRS3220 and C09 clones were classified as susceptible, with RF of 1.93, 1.95, 2.00, 2.31, 2.32 and 2.35. The BRS3193, C160 and BRS2357 clones were classified as very susceptible, with RF values of 3.03, 4.41 and 5.82, respectively. The clustering based on the genetic diversity of morphological traits indicated that genotypes more similar to the Robusta botanic variety had lower RF. The hybrid plants showed intermediate degrees of resistance indicating the segregation for the character of the M. incognita resistance. The clones BRS3210, C12, BRS2299, BRS2314, BRS3137 and BRS1216 expressed resistance responses to M. incognita with potential for growing resistant genotypes in the Western Amazon.

Abstract: A bananeira é uma importante frutífera para o Brasil, pois gera emprego e renda tanto na zona rural quanto urbana. Estudos de qualidade físico-químicas dos frutos são importantes para os produtores, já que podem ser utilizados para definir a época de colheita adequada. Objetivou-se com este trabalho avaliar as características relacionadas à qualidade pós-colheita de banana, cv. D'angola, em diferentes épocas de colheita, produzidas nas condições de Rio Branco-AC. O experimento foi conduzido no Campo Experimental da Embrapa Acre, sendo utilizado delineamento em blocos casualizados com quatro tratamentos e cinco repetições. Os tratamentos foram compostos pelas épocas de colheita de fevereiro, março, abril e maio de 2014. Avaliou-se o comprimento e o diâmetro do fruto, a acidez total titulável (ATT), o teor de sólidos solúveis totais (SST), a relação SST/ATT (Ratio) e o potencial hidrogeniônico (pH), além da luminosidade (L*), cromaticidade (C*) e ângulo ºHue. Os valores médios obtidos foram: comprimento do fruto= 27,35 cm; diâmetro do fruto= 50,63 mm; ATT= 0,54; SST= 17,48 °Brix; Ratio= 34,22; pH= 4,86; L*= 65,83; C*= 50,27; e ºHue= 85,27. As épocas de colheitas não influenciaram nas características pós-colheita dos frutos de bananeiras avaliados. As bananas produzidas entre fevereiro e maio possuem qualidade pós-colheita dentro do padrão aceito para comercialização. The banana tree is an important fruit for Brazil, as it generates employment and income in both rural and urban areas. Physical-chemical quality studies of fruits are important for producers, since they can be used to define the appropriate harvesting season. The objective of this work was to evaluate the characteristics related to postharvest quality of banana, cv. D'angola, at different times of harvest, produced under the conditions of Rio Branco-AC. The experiment was conducted in the Experimental Field of Embrapa Acre, using a randomized block design with four treatments and five replicates. The treatments were composed by the harvesting dates of February, March, April and May of 2014. The length and diameter of the fruit, total titratable acidity (ATT), total soluble solids (TSS), SST/ATT (Ratio) and hydrogenation potential (pH), besides luminosity (L*), chromaticity (C*) and ºHue angle. The average values obtained were: fruit length= 27.35 cm; fruit diameter= 50.63 mm; ATT= 0.54; TSS= 17.48 °Brix; Ratio= 34.22; pH= 4.86; L*= 65.83; C*= 50.27; and ºHue= 85.27. The harvesting times did not influence the post-harvest characteristics of the evaluated banana fruits. Bananas produced between February and May have post-harvest quality within the accepted standard for marketing. Made available in DSpace on 2019-12-03T00:36:57Z (GMT).

Abstract: Identification of high yielding and stable genotypes is one of the main goals in all breeding programmes Estimation of hybrids is often aggravated due to the presence of genotype x envi- ronment (GE) interaction One of the ways to eliminate negative effect of this interaction is the application of reliable statistical models such as AMMI model, which singles out high yielding and stable genotypes that have positive reaction to the improvement of production environments This research aimed to establish specific maize hybrids interactions in different environments in two years by AMMI analysis Twelve KWS maize hybrids belonging to FAO 400-500, were exam- ined in two years over eight locations in Vojvodina The highest yield in both years had the hybrid KWS2 (12 764 kg ha-1) Based on the AMMI1 model, hybrid KWS9 showed the highest stability and adaptability at all locations According to AMMI2, hybrids KWS1, KWS3 and KWS12, had the highest stability and adaptability, while hybrids KWS2, KWS6, KWS8, KWS9 and KWS10 showed a satisfactory level of stability and it is necessary to pay attention to which locations they have positive interactions in order to be recommended in such regions Nevertheless, based on the AMMI2, locations Temerin, Kikinda and Zrenjanin, showed similar interaction response, which points out that the number of trial locations could be reduced Obtained results would contribute to the more precise decision in hybrids recommendation for the certain region, but also in defining further aims in maize breeding., Identifikacija visoko prinosnih i stabilnih genotipova jedan je od vodećih ciljeva u svim ople- menjivačkim programima Pravilna procena hibrida je često veoma otežana usled prisustva in- terakcije genotip/spoljašnja sredina Jedan od načina da se eliminišu negativne posledice interak- cije je da se primenom pouzdanih statističkih modela, kao što je AMMI model, izdvoje stabilni, visoko prinosni genotipovi, koji pozitivo reaguju na poboljšanje uslova u kojima se gaje Cilj ovog rada bio je da se metodom AMMI analize pronađu i utvrde specifične interakcije hibrida kukuruza u različitim sredinama u dve godine istraživanja Odabrano je 12 KWS hibrida kuku- ruza FAO 400-500, koji su ispitivani u dve godine na šest lokaliteta u Vojvodini Najveći prinos u obe godine ispitivanja imao je hibrid KWS2 (12 764 kg ha-1) Na osnovu AMMI1 modela hibrid KWS9 je pokazao najveću stabilnost i adaptabilnost na svim lokacijama Analizom AMMI2 bi- plota utvrđeno je da hibridi KWS1, KWS3 i KWS12 pokazuju najveću stabilnost i adaptabilnost, dok hibridi KWS2, KWS6, KWS8, KWS9 i KWS10 pokazuju zadovoljavajući nivo stabilnosti i potrebno je obratiti pažnju sa kojim lokacijama ostvaruju pozitivne interakcije i u tim regionima ih preporučivati Takođe na osnovu AMMI2 biplota, lokacije Temerin, Kikinda i Zrenjanin su pokazale vrlo sličan interakcijski odgovor, što ukazuje na mogućnost smanjenja broja lokacija za izvođenje ogleda Rezultati dobijeni ovim istraživanjem će doprineti preciznijem i kvalitetnijem odlučivanju prilikom izbora hibrida koji će se gajiti u određenom regionu, ali i definisanju daljih pravaca u oplemenjivanju kukuruza.
