Seven soybean genotypes were evaluated across three seasons to identify genotypes suitable for different seasons and dates of sowing. Percent variance contributed by genotypes main effects was more to total genotypic variability than that contributed by seasons, dates of sowing genotypes × seasons interactions and genotypes × dates of sowing interactions for 50% flowering, number of branches and 100 seed weight. Seasons and dates of sowing main effects contributed more to total genotypic variability than genotypes, GSI and GDOSI for plant height, number of pods and grain yield. DSb 21, DSb 23 and KBS 23 showed lowest estimates of AMMI Stability Value and Stability Index for grain yield are widely adopted genotypes.
