The aim of the paper is to reveal how the proliferation of Airbnb is shaping hotel room and short-term accommodation rates in Budapest, which areas are most affected and whether there is any spatial concentration. We performed a manually made internet data query and applied GIS-based mapping methods to visualise the spatiality of Airbnb in Budapest and highlight the differences in room rates. Our results show that both the hotel and Airbnb supply concentrates mainly in the centre of the city, causing fierce competition between hotels and Airbnb hosts. Furthermore, Airbnb also has a strong impact on the rental market through the increasing rental prices.

The aim of the paper was to investigate the impact of different accommodation attributes on Airbnb listing prices in a touristic area. The study applied hedonic price modeling utilizing a sample of 2417 Airbnb accommodation rental offers in the Lake Balaton Touristic Region in Hungary. Our results revealed that property-related attributes significantly influence Airbnb prices although the magnitude of these effects is very diverse and complex. The OLS findings showed that the provision of air conditioning, free internet, and free parking are the main determinants of Airbnb price in the sample area, while the number of available photos and the presence of a kitchen does not significantly influence the price. The quantile regression results further demonstrated that capacity, the provision of breakfast, and TV leads to higher prices among the higher-priced accommodations, while the number of bedrooms and bathrooms, smoking, and free parking influence more the prices of lower-end accommodations.

An investigation was undertaken to ascertain the presence of root-knot nematodes belonging to Meloidogyne species in Romanian crops, other than vegetables, to which they are very dangerous. Based on morphobiometrics and molecular characterization, three species of Meloidogyne were identified, i.e. M. incognita on cactus (Mammillaria backebergiana), M. arenaria on grapes (Vitis vinifera) and M. hapla on blueberry (Vaccinium myrtillus). PCR amplification and sequencing of the ITS containing region, the mitochondrial intergenic region between the cyochrome oxidase II and the 16S rRNA genes and the SCAR species-specific markers were used to identify Meloidogyne species from Romanian samples. Both SCAR sequences and PCR-RFLP analyses were able to quickly distinguish the four different Meloidogyne species in Romania. Meloidogyne arenaria has been reported for the first time on grapewine in Romania.

Trabajo presentado en la V Meeting Asociación Española de Leguminosas, AEL (Eucarpia International Symposium on Protein Crops), celebrada en Pontevedra del 4 al 7 de mayo de 2015., Pea (Pisum sativum L.) is one of the most widely grown grain legumes in Europe. Two main constraints in pea cultivation are stem lodging and ascochyta disease. Both of them may lead to severe yield loss. There are no totally resistant cultivars. Stem lodging and ascochyta disease resistance are quantitative traits. The QTL analysis for these traits were performed on two pea mapping populations for which linkage maps were available (Carneval x MP1401 for lodging resistance and P665 x Messire for ascochyta disease resistance). Common markers were used to compare QTLs localizations in the two pea linkage maps.

Trabajo presentado en el IV International Ascochyta Workshop (Ascochyta 2016), celebrado en Tróia (Portugal) el 10 y 11 de octubre de 2016., Ascochyta blight disease is one of the main constraints for pea cultivation. QTL analysis were performed in [P665×Messire] and [Wt10245×Wt11238] pea mapping populations to identify the genomic regions controlling resistance to ascochyta blight. Disease assess ments were performed under field conditions during 5 years at Radzików, Poland, using the scale reported by Xue et al. (1996) (0 –resistant, 9 –susceptible). Average ascochyta disease (AAD) scoring was 2.09 for [P665×Messire] RIL population, 2.5 for Mes sire and 1.5 for P665 in 2008. In 2009 (AAD) scoring for this population was 4.14, 5 for Messire and 3.5 for P665. In 2013 (AAD) scoring was 4.18, 5.5 for Messire and 2.7 for P665. In 2014 (AAD) scoring was 4.05 and 5.0 for Messire. In 2015 (AAD) rating was 3.98 and 4.8 for Messire. Therefore P665 was more resistant to ascochyta blight than Messire under our field conditions as reported previously by Fondevilla et al. (2008). Average ascochyta disease scoring value was higher for [P665×Messire] than for [Wt10245×Wt11238] population [(AAD) for population 3.6, 3 for Wt10245 line and 4 for Wt11238 line in 2011, 4.36 for the RIL population, 3.3 for Wt10245 line and 4.9 for Wt11238 line in 2014]. Three QTLs associated with resistance to ascochyta blight were identified on [P665×Messire] linkage map. QTLs were not conserved across the years what may be due to the strong influence of environmental conditions on the measured traits. Seven QTLs associated with resistance in 2011 and four associated with resistance in 2014 were detected in the [Wt10245×Wt11238] population. Two QTLs were found in the same genomic region in both populations (in LGIIIB, near AA170 and in LGVB, near Pis_GEN_27_2_1 and AD280 marker). QTLs in similar intervals were detected by Carrillo et al. (2014) in Spanish conditions, suggesting the existence of genetic factors controlling resistance effective in different genetic backgrounds and environments: one in LGIII (near AA170 marker) and two in LGV (near AD280 marker0. According to these authors some genes co-localizing with QTLs may have an interesting role in defense and therefore, they could be candidate genes involved in resistance to D. pinodes in P665., The study is supported by National Multi-Year Program “Improvement of domestic sources of plant protein, their production, economy and feeding technologies”.
