The study was conducted in the Trakya region, Turkey at five environments during the 2015-2016 growing cycles. Grain yield were subjected to analysis of variance (ANOVA), the additive main effect and multiplicative interaction (AMMI) and genotype and genotype-by-environment (GGE) biplot analyses. ANOVA and AMMI analysis showed highly significant (p < 0.01) differences among environments (E). Environment was responsible for the greatest part of the variation, followed by genotype and its interaction effects. Average yield across five environments varied from the highest 6673 kg ha-1 to the lowest 5008 kg ha-1. Across five environment Genotypes G7 and G12 had highest grain yield. Burgaz was found near the ideal test environment of the average environment coordination. Therefore, this location should be used as the most suitable to select widely adapted genotypes. For grain yield, cultivars Gelibolu, and G17, G8, and G12 lines were well adaptable to all environmental conditions. The graphical result showed that the first principal component PC1 explained 44.71% of the interaction sum of the square while the second principal component, PC2 explained 22.57% of some of the square interaction. The result of PCA revealed that the 2 principal components contributed 67.27% of the total variability. In the study, genotypes G12 and G17 selected in 2016 and then were released in 2019 named Anafarta and Abide, respectively.
