The present study was conducted with seventeen advanced lines of pigeonpea along with three checks (Pusa 992, Paras and UPAS 120). The experiment at each location was laid out in a Randomized Block Design (RBD) with three replications. The result of pooled ANOVA revealed that G × E interaction was significant for most of the characters except number of primary branches/plant, number of secondary branches/plant, number of seeds/pod, main shoot length and seed yield per plot. The presence of significant G x E is must as further analysis is possible only if there is a reliable genotype x environment interaction and hence, for number of primary branches/plant, number of secondary branches/plant, number of seeds/pod, main shoot length and seed yield/plot no further analysis was carried out. The traits in which G x E interaction was found significant were analysed by using Eberhart and Russell’s model and it was found that for days to 50% flowering, the check Paras was found as most stable across all environments however for days to maturity, plant height and 100-seed weight none of the genotype was found to be stable across all environments. The most stable genotypes exhibiting higher stability for number of pod/plant across all environments was PA 538 followed by PA 540.
