Abstract

The experiment was conducted involving 96 genotypes of black gram for genetic variability of 13 quantitative traits at Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur. The analysis of variance (ANOVA) revealed existence of significant differences among the genotypes for all the characters studied. Among the genetic parameters phenotypic coefficient of variation (PCV) was higher than genotypic coefficient of variation (GCV) for all the traits indicates the role of environment in expression of the characters. High GCV and PCV were maximum in case of biological yield followed by number of pods per plant, number of pod clusters per plant, harvest index, seed yield per plant and plant height. Characters like plant height, number of pod clusters per plant, number of pods per plant, biological yield, seed yield per plant and harvest index shows high heritability coupled with high genetic advance. Correlation and Path analysis studies revealed that the important yield attributing traits like biological yield, harvest index, number of pods per plant, pod length, 100 seed weight exhibited a highly significant correlation values both at phenotypic and genotypic levels. Further, the same traits also exhibited a higher value of direct effects on seed yield per plant. Hence, these traits should be given the top priority while developing the superior hybrids in blackgram.
