    Abstract

    Twelve pigeonpea genotypes comprising ten hybrids and two controls were evaluated at three environments during rainy season of 2012-13, to study genotype × environment interaction for yield and related traits. Analysis of variance in each environment and on a pooled basis expressed a significant difference among genotypes for yield and yield contributing characters except for 100 seed weight. Genotype × environment (linear) interactions were found significant for days to 50% flowering, plant height, primary and secondary branches per plant, pods per plant, seeds per pod, grain yield per plant and yield (kg/ha) except days to maturity and 100 seed weight. The regression and GGE biplot methods were used for analysis. Both methods identified ICPH 2671, ICPH 2740, ICPH 3933 and ICPH 3762 as stable hybrids. The GGE biplot explained higher proportion of the mean sum of squares of the G×E interaction and was more informative with regards to environments and their genotypic performance than the regression method. Hybrids ICPH 2671, ICPH 2740, ICPH 3762 and ICPH 3933 showed stability for the yield and yield components and could be recommended for cultivation.
