The present investigation was carried out to study stability performance over three environments for seed yield and its components in 13 advanced breeding lines (including five parents) of soybean using a randomized complete block design. The partitioning of (environment + genotype x environment) mean squares showed that environments (linear) differed significantly and were quite diverse with regards to their effects on the performance of genotypes for seed yield and most of the yield components. Stable genotypes were identified for wider environments and specific environments with high per se performance (over general mean) for seed yield per ha. On the basis of stability analysis of individual characters, the genotype DSb 21 was identified as stable genotype for all the characters studied with higher mean across environments. For seed yield, genotype DSb 23-2 was high yielder across environments compared to the check JS 335.
