Stability analysis for seed yield in blackgram (Vigna mungo L. Hepper)

Abstract

Stability analysis was carried out for seed yield over three different seasons using 42 F1 hybrids obtained by line × tester mating design with 14 lines and three testers of blackgram genotypes. The analysis of variance revealed that the mean sum of square was significant for seed yield due to varieties, environments (linear) and varieties × environments indicating that variability was present among the genotypes. Out of 42, five hybrids viz., IC 587753 × PU 19, IC 587753 × LBG 20, IC 436720 × PU 19, IC 519805 × PU 19 and IC 587752 × T 9 proved the best over three environments for seed yield. Environment 1 (kharif) was the most favourable for the better expression of seed yield.
