Studies on determining genotype-environment interactions and stabilities of some lines and cultivars of hungarian vetch (Vicia pannonica Crantz.) for important agronomic traits in Diyarbakir ecological conditions

The study was conducted to determine genotype x environmentinteractions and stability status of twelve Hungarian vetch (Vicia pannonicaCrantz.) genotypies in terms of forage yield, seed yield and some agronomictraits, which are highly effective on forage and seed yield, in ecological conditionsof the Diyarbakır. For this reason; experiments were performed in five locationsof the region in the 2008/2009 and 2009/2010 growing seasons. The experimentswere established according to randomized blocks design with three replications.According to results of the study; genotypies were significantly affectedby the years and conditions of the locations in terms of examining all of the traits,but, the effect of locations on genotypes was found higher than the years forexamining the traits. It has been determined that Hungarian vetch genotypies haveshown different adaptability in different environments for all of the traits.In the end of the study, carried out in different two years and fivelocations, It has been determined that although Ege Beyazı-79 cultivar is the moststable genotype in terms of both green forage yield and dry forage yield, Oğuz-2002 cultivar is the most stable genotype in terms of seed yield in ecologicalconditions of Diyarbakır.
