The present study entitled “Genetic Divergence in Black gram [Vigna mungo (L.) Hepper]” was conducted with 56 genotypes and two checks namely Pant U-31 and Pratap Urd-1during Kharif- 2019 at the Experimental farm, RCA, MPUAT, Udaipur. The genotypes were planted in augmented RBD design in four blocks. Mean squares due to genotypes were significant for plant height, number of branches per plant, number of pods per plant and pod length out of twelve characters as divulge from ANOVA. Present investigation results revealed that character seed yield per plant showed high GCV, heritability and genetic gain. Maximum heritability was found for pod length followed by plant height, number of branches per plant, number of pods per plant and seed yield per plant. While, maximum genetic gain was observed for seed yield per plant followed by number of pods per plant, number of branches per plant, plant height and biological yield. In general, PCV was higher than GCV for all the characters. Seed yield per plant was significant positively correlated at both genotypic as well as phenotypic levels with number of branches per plant, number of pods per plant, pod length, number of seed per pod, biological yield and harvest index. In cluster analysis, black gram genotypes were divided into VI clusters. Average inter cluster distance values were maximum between cluster V and VI (34.298). Cluster VI possessed genotypes with early flowering and maturity, plant height, number of branches per plant, pod length and harvest index From, the present investigation it can be concluded that genotypes KPU-129-104, RBU-38, KU-16-89, KU-16-96, KPU-1098, TBU-2, KPU-11-37 appeared promising Presence of significant genetic variability and diversity among the tested genotypes of urdbean would be favorable for obtaining superior progenies in future breeding programme.
