Association panels represent a useful tool for quantitative trait loci (QTL) mapping and pre-breeding. In this study, we report on the development of a European and Mediterranean chickpea association panel as a useful tool for gene discovery and breeding. Chickpea (Cicer arietinum L.) is one of the most important food legumes worldwide and a key crop in the Mediterranean environments. The selection of genotypes followed criteria aimed to build a set of materials representative of the genetic diversity of chickpea germplasm focusing on the European and Mediterranean environments, which have largely been ignored to date. This tool can help breeders to develop novel varieties adapted to European and Mediterranean agro-ecosystems. Initially, 1931 chickpea accessions were phenotypically evaluated in a field trial in central Italy. From these, an association panel composed by 480 genotypes derived from single-seed descent was identified and phenotypically evaluated. Current and future phenotypic data combined with the genotypic characterization of the association panel will allow to dissect the genetic architecture of important adaptive and quality traits and accelerate breeding. This information can be used to predict phenotypes of unexploited chickpea genetic resources available in genebanks for breeding. [ABSTRACT FROM AUTHOR]

Sunflower is one of the most important oilseed crops cultivated in the world for different purposes. In Italy, the production is mostly located in the central area, representing 70% of Italian production. The market demand for sunflower oil is higher than the national production. There is an increasing request for cold pressed sunflower oil for food application. The success of this activity is linked to a correct setting up and management of the production and supply chain with a valorization of products and by-products. To this aim, information is needed, and this paper is focused on the cultivation of sunflower in central Italy using suitable hybrids, as well as on the study of the cold extraction performance of the sunflower seed produced and the quality of by-products and residues. Results indicate that, on average, a range of about 1.0–1.5 t ha
−1 of cold pressed oil and different amounts of by-products can be obtained. According to a proposed scenario, 30 ha cultivated with sunflower are needed to create a complete supply chain within the farm, avoiding many additional passages and maintaining all the value for the farmer. It is important to use suitable hybrids for obtaining good yield, but also the cold extraction performances are important because they also affect the quality of by-products and residues that can be valorized themselves to improve sustainability.

Currently the biodiesel chain is promoted by the European energy policy. For the Italian scenario the sunflower is one of the most important crop to be considered for biodiesel production but the chain is not fully profitable. This problem could be solved with the increase of farm incomes through a proper valorization of by-products. From this point of view the oilseed crop is not considered only for oil production but also for producing multiple products with the same economic value. This is the main inspiring concept of the Extravalore project. The sub-project “Raw Materials” investigated about the possible influence of different agro-technics performed in three distinct geographical environments (Northern, Central and Southern Italy) on the characteristics of by-products obtained from sunflower crop. A national net of experimental tests was set during the 2010–2013 period in order to evaluate the adaptability and the potential production of high oleic sunflower hybrids. 7 seed companies supplied the 20 genotypes assessed in total (18 high oleic hybrids and 2 as control), 11 of them were evaluated all the three years. Achene yields of tested high oleic hybrids were extremely variable: from 2.05 t ha −1 to 4.04 t ha −1 in Northern Italy, from 2.50 t ha −1 to 4.24 t ha −1 in Central Italy and from 2.09 t ha −1 to 2.68 t ha −1 in Southern Italy. For this reason, it was necessary a precise characterization of varieties before their cultivation. The cultivar screening showed general difficulty for high oleic hybrids to reach the performances of achene and oil yields of the conventional ones. In particular, LG55.57HO and PR64H31 resulted the best high oleic cultivars for Northern Italy; many of the high oleic tested cultivars performed well for Central Italy and also for Southern Italy but with a higher variability. The highest potential production was registered in Central Italy; Northern Italy gave decreased but similar results, despite the different latitude; in Southern Italy the productions were 20–30% lower, even with the irrigation support. All high oleic tested cultivars showed oleic acid content in lipid fraction always above the 84% in Central Italy, meaning a stability of the character, very important for the biodiesel production.

The Extravalore project aims to give added value to oilseed crops, considering them also for producing multiple products with the same economic value and being interesting for the market thanks to their various utilizations. An evaluation of the main cultivars of Brassica napus subsp. oleifera and Brassica carinata has been performed within the project, analyzing them in three Italian locations with different climatic conditions (Palazzolo dello Stella – North Italy, Osimo – Central Italy, Cassibile – South Italy) to assay their adaptability and production potential. During the 2010–2013 period, 43 varieties of rapeseed were evaluated, but only 13 of them for all the period considered; moreover, also 4 varieties of B. carinata were tested. The seed yields of tested cultivars of rapeseed varied a lot among locations, depending also by the seasonal trend. Central Italy was the less disadvantaged by climatic conditions: on average, it was reached a seed yield of 4 t ha −1 , a theoretical oil production of 1.63 t ha −1 and more than 8 t ha −1 of crop residues. In Northern and Southern Italy, if compared with Central Italy values, the seed yields were both lower than 30% and theoretical oil productions lower than 60%; moreover, crop residues in Northern Italy were 12% lower than in Central Italy while in Southern Italy 65% lower. The agronomic behavior of varieties differed a lot among the three experimental areas: DK Expower was the best at North; Albatros, Artoga, Exagone and Excalibur in Central Italy; Excalibur, Zoom and PR46W14 at South Italy but none of them reached a seed yield of 2 t ha −1 . Concerning B. carinata , the cultivars did not give good productions in any of the experimental areas, mainly because of the low oil content in the seeds. Even in Central Italy, where the best results were registered, the seed yield was on average 28% lower than in rapeseed and oil production 10% lower; the crop residues were double than rapeseed. In any case, the valorization of the crop residues is important with a wide range of possible utilization from the direct energetic use to the biochemicals extraction with consequent environmental advantages due to the substitution of dedicated or fossil feedstock with crop residues.
