| Abstract | ||
| In this study 25 wheat genotypes including 22 advanced lines along with two durum (Saji and Zardak) and one bread (Sardari) wheat cultivars were grown in 19 diverisified environments in Kermanshsah, Ilam, Maragheh and Shirvan under both rainfed and supplemtary irrigation conditions during four cropping seasons (2006-2010) in Iran. The large magnitude of the GE interaction in combined-ANOVA of grain yield relative to genotypic effect, sugessted the possible existence of sub-environmental groups for the genotypes. The GGE biplot analysis showed that the cold environments were seprated from the warm environments and these two groups gave dissimilar results in ranking of genotypes. The moderate eviormnents were correlated with the both warm and cold environment groups. The genotypes G8, G17, G23 (Saji), G11, G21 and G19 could be recommended as genotypes with high yield and stability performance. The genotypes G21, G16, G8, G23 (Saji) and G17 were highly adapted to warm environments, while the genotypes G25 (Sardari), G24 (Zardak) and G6 were highly adapted to cold environments. The genotypes G20, G22 and G19 can be considered as genotypes with general adaptability.. | ||
