Yield Stability Analysis in Maize Hybrids of Southwest China under Genotype by Environment Interaction Using GGE Biplot

Selecting superior genotypes across different environments is vital for varietal release, crop planting, and commercial use. Therefore, the objectives of this research were to appraise performance hybrids approved in recent years diverse environments, recommend high-yielding stable wider adaptation. Fourteen single cross maize hybrid (G), including a check, implemented ten (E) two seasons (2020 2021). The combined analysis variance revealed that G, E, their interactive (GEI) significantly (p < 0.01) affected grain yield. Moreover, mean yield ranged from 9333 kg ha−1 HH-2 (2021) 13,195 LD-18 (2020). “which won where” GGE biplot existence mega with own best (LD-18 LD-29 2020; LD-18, LD-19, YY-1506 “mean vs. stable” suggested ZY-811, highest/middle productive high stability 10 closest ideal genotype.
