Abstract
The experiment was conducted involving 89 genotypes of blackgram for genetic variability of 18 quantitative and qualitative traits at S.V. Agricultural College, Tirupati during Rabi, 2015-16. The analysis of variance (ANOVA) revealed existence of significant differences among the genotypes for all the characters studied. Among the genetic parameters PCV was higher than GCV for all the traits indicates the role of environment in expression of the characters. Higher estimates of genotypic coefficient of variation was observed for the traits tryptophan content, lysine content, methionine content, number of primary branches per plant, seed yield per plant, number of pods per plant and number of clusters per plant. High heritability accompanied with high genetic advance was observed for methionine content, tryptophan content, lysine content, number of clusters per plant, number of primary branches per plant, seed yield per plant, harvest index, number of pods per plant, carbohydrate content and plant height specified dominance of additive gene action in appearance of these traits and selection for these characters will be effective.
