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.
