The genetic potential of black gram genotypes which were introduced from Bhava Atomic Research Centre (BARC) along with national check PU-31 and VBN-11 and local check were evaluated to find out 14 genotypes of their quantitative characters for future crop improvement programme. The current investigation was carried out in a Complete Randomized Block Design (CRBD) in the University Research Farm of Uttar Banga Krishi Viswavidyalaya. Fourteen black gram genotypes including local and national checks were sown on Pre- Kharif (March) 2023 at Research Farm, Uttar Banga Krishi Viswavidyalaya, Pundibari. The data were recorded for 9 morphological characters and biometrical analysis was done to estimate Analysis of Variance (ANOVA) along with Genotypic and Phenotypic Co-efficient of Variation, heritability in broad sense, genetic advance. From the ANOVA, all the genotypes were found significant in the investigation for all the quantitative characters. High GCV were observed for Peduncle length (41.38) followed by no. of primary branches (37.17), Yield (28.94), Number of seeds (25.85), No. of leaves (20.02) and No. of pods (20.92). Highest heritability was found in peduncle length (93.21%) followed by number of seeds (91.03%), number of primary branches (89.49%), Numbers of pods (87.22%), yield (86.41%), Number of secondary branches (72.54%), Pod length (71.80%), Number of leaves (70.36%) and Plant height (67.11%). High-genetic advance as percent of mean was higher for Peduncle length (82.61%) followed by number of primary branches (72.44%), yield (55.41%), number of seeds (50.81%), Numbers of pods (40.25%), Number of leaves (34.60%), Number of secondary branches (34.30%), Plant height (24.74%) and Pod length (23.95%). So the characters which were found to have high GCV, heritability and Genetic gain can be utilized for future crop improvement programme because of the presence of additive genetic effects with less environmental interactions and higher stability of heritable characters in future generations.
