بررسی پایداری عملکرد دانه ژنوتیپ‌های گندم دوروم با استفاده از روش‌های کلاسیک پارامتری

There are different methods for determininig of Genotype × environment interaction. In this research 16 selective genotypes of durum wheat from previous advanced yield trials have been cultivated along with Saimareh and Dehdasht check cultivars during three years (2008-2010) in five locations including Gachsaran, Gonbad, Khoramabad, Moghan and Ilam based on Randomized Complete Block Design with four replicates. After combined analysis of variance was conducted and then some univariate parametric methods, including Roemer phenotypic stability method, Finlay and Wilkinson regression coefficient, Wricke stability index, Plaistd statistics, Plastd and Peterson statistics, Shukla variance, environmental coefficient of variation of Francis and Kannbrg, Hanson statistic and Lin and Binns statistics those are indeed, the stability of classical methods are used to analyze genotype × environment interactions. Finally genotypes 13, 14, 16, 3 and 4 had the lowest impact on genotype × environment interaction and were selected as the most satble genotypes.
