The study was car ried out to analyze grain yield performances of nine varieties and sixteen advanced barley genotypes across eight environments of Southeastern Anatolia, Turkey, between 2003-2007 growing seasons. The experimental layout was randomized complete block design with four replications. Additive main effects and multiplicative interactions analysis (AMMI) revealed that the yield performances of genotypes were under the main environmental effects of genotype by environmental interactions. The first two principal component axes (IPCA 1 and IPCA 2) were significant (P<0.01) and cumulatively contributed to 61.07% of the total genotype by environmental interaction. According to the AMMI biplot analysis, genotype G17 and G21 had the desirable characteristics of high or moderate stability with high grain yield and were thus recommended for commercial release in Turkey and genotypes G7, G9 and the G8 proved to be valuable sources for yield stability in barley breeding programs.
