摘要： The purpose of this study was to test the stability and overall adaptability of promising maize hybrids in terms of grain yield (GY), ear weight (EW) and 100-kernel weight (KW) in multi-environments trials (Mets). Twelve maize genotypes were carried out with three replications in a randomized complete block design across eight locations in 2017-2018 using AMMI (additive main effect and multiplicative interaction) and GGE (genotype, genotype x environment) biplot. The analysis of AMMI model indicated that three agronomic traits all showed highly significant differences (P < 0.01) on genotype, environment and genotype by environment interaction. Genotypes G9, G10 and G3 showed higher stability on GY, EW and KW, respectively. Environments El and E2 had better discrimination on the three agronomic traits of the tested genotypes. Genotypes G8 and G9 showed good performance in terms of GY, whereas G2 and G12showed broad adaptability for EW. It was also found that the genotypes with better adaptability in terms of KW were G5 and G12.
