Stability Analysis for Physiological Parameters and Seed Yield in Blackgram

Stability analysis of variance revealed significant differences among the genotypes and environments for all the physiological parameters and seed yield except LWR at pod-filling stage. The linear component of genotype-environment interaction was significant for LAR at pre-flowering and pod-filling, LWR at flowering, SLA and NAR at pod-filling along with seed yield. Stability in seed yield was found associated with stability in physiological parameters like LAI, SLW, NAR and CGR.
