Evaluation of genotype by environment interaction (GEI) is very important for development of crop varieties with good potential. In this study, Eberhart - Russell’ and AMMI approaches were used to analyse the pattern of stability under targeted environment. The pattern of stability parameters of seed yield indicated that two genotype viz., G2 and G36 exhibited high mean seed yield with non-significant s2di, whereas G33 showed average seed yield (mean) and nonsignificant s2di. Environmental indices indicated that environment A and environment B were most favourable for most of

the yield component traits, whereas environment C was unfavourable for almost all the yield and yield component traits.

Based on AMMI 1; G1, G2, G18, G4, G3, G24, G22 and G25 were found stable for seed yield. For seed yield; genotypes and environments were grouped into nine sectors (AMMI 2). The first sector consist of with environment B with high IPCA score for some outlier genotypes i.e. G25, G14 and G22, indicated that the environment B was better than other environments and three genotypes were found stable for SYP. The selected genotypes may be utilized in Vigna radiata improvement programme at targeted location with true type of breeding lines.
