PHENOTYPIC STABILITY FOR SEED YIELD IN BLACK GRAM

Abstract

Eight black gram genotypes were studied during five seasons for their stable performance for seed yield. The results indicated that varieties Vamban 1, LBG 17 and Co 5 were stable. Vamban I recorded below average responsiveness to environment and Co 5 as average responsiveness to environment. Genotypes VBG 20, Vamban 1, VBG II and T 9 recorded high mean seed yield. Hence, the variety Vamban 1 may be recommended to all environment because of its low responsiveness to environment with high seed yield.
