Genotype by Environment Interaction Analysis for Grain Yield of Wheat (Triticum aestivum (L.) em.Thell) Genotypes

Genotype environment interaction and stability performance were investigated on grain yield per plot in eight environments during Rabi (here, rabi means that a crop has been grown season: crops are sown winter harvested spring the Indian subcontinent) 2019–2020 2020–2021 using 100 diverse wheat genotypes. Research was conducted at Chaudhary Charan Singh Haryana Agricultural University, Hisar, India. The analysis of variance revealed genotype, their had highly significant effect as reflected Eberhart Russel model Russell indicated suitability genotypes WH 1142, PBW 661, 475 DBW 17 with high mean, bi > 1 non-significant deviation from regression to favorable environment, whereas UP 2660 88 < found suitable for poor environment. Additive Main Effects Multipicative Interaction (AMMI) across showed 26.41% total variation attributed genotypic effects, 70.22% environmental effects 3.37% genotype × effects. AMMI biplot study 750, DPW 621-50, 542, 486, 661 1192 stable they did not exert strong interactive forces; hence, selected potential candidates possible release areas. Furthermore, which-won–where adaptation 706, 769, 116, 1157, 789 WH1186 first mega-environment 16, 1152, 1105 503 second.
