Abstract: Genotype x environment interactions through different stability parameters and performance of the traits of genotypes were studied. The traits were; days to maturity, number of branch/plant, 100 seed weight and seed yield/plant in ten soybean genotypes across five environments represented by sowing dates. Significant difference were observed for genotypes, environments and genotype-environment interaction. Stability analysis after Eberhart and Russell’s model suggested that the genotypes used in this study were all, more or less responsive to environmental changes. Most of the genotypes perform better in Env. 3 (5th January date of sowing). Based on phenotypic indices (Pi), regression (S2di) genotype colombus was found stable for days to maturity. Shohag, BS-60, G-2120 and Cobb were identified as stable for number of branch/plant, whereas; the genotype BS-60 was found stable for 100 seed weight. The genotype BS-60 and Cobb were considered as most stable genotypes for seed yield/plant. In general the genotype BS-60 was found stable for most of the characters studied.
