Information on genotypes, which can be adapted to a wide range of environments, is one of the most important goals of plant breeders in a crop improvement program to set appropriate breeding strategies and improve wheat production. So, the objectives of this study were to (i) estimate the effect of the environment on yield and yield-contributing characters, (ii) determine desired genotypes with high yield and stability by estimating stability via different stability analysis techniques. Forty-nine wheat genotypes were evaluated in a 7 x 7 lattice design with two replications three locations. Based on the combined analysis of variance results, the majority of the traits had a significant difference (p<0.01) within location, genotype, and GEI. The observed significance differences among genotypes for the traits under study generally indicated the presence of genetic variations among the genotypes, and genotypes react differently depending on the tested environmental conditions. According to AMMI analysis, genotypes, environments, and their interactions have a considerable impact on grain yield. Variety Alemtena, Denbi, Mangudo, and genotypes DWNL19209 show high stability with high seed yield using all stability analyses. The information obtained in the present study could be used to examine stable genotypes for narrow and broad environmental adaptability.
