The effect of genotype (G), environment (E) and G × E interactions on days to 50% flowering, primary branches, number of pods per plant, pod length, plant height, 80% maturity,100 seed weight, protein % and seed yield per plant were found significant at P=0.05. The highest mean seed yield was obtained from RbnG8 (37.82g). The genotype Rbng5, Rbng6 and RbnG8 recorded less number of days for 50 per cent flowering and 80% maturity across the six environments. Correlation studies indicated that yield/plant was significantly positively associated with pod length, number of seeds per pod, 100 seed weight at both phenotypic and genotypic level. The best genotype for seed yield across the environments was RbnG5, RbnG8 and RbnG12 and RbnG4 and RbnG5 were intermediate and RbnG13 was the least. Thus, partitioning G × E into adaptability and phenotypic stability will positively address the information gap on association of traits to yield.
