The experimental material was consisting of 41 Black gram genotypes, check as T-9, during kharif 2017. The experiment was laid out in Randomised Complete Block Design with 3 replications at field experimentation centre of Department of Genetics and Plant Breeding, Sam Higginbottom University of Agriculture, Technology & Sciences. The observations were logged on five randomly taken plants to each treatment and replication for 13 quantitative characters viz. days to 50% flowering, days to 50% pod setting, plant height, number of primary branches per plant, clusters per plant, pods per plant, pod length, seeds per pod, days to maturity, seed index, biological yield, harvest index and seed yield to estimate the variability, heritability and genetic advance as % mean, character association and path analysis. High heritability along with high Genetic advance as % mean was observed for harvest index and seed yield per plant represents simple selection is effective to improve these characters. The correlations revealed that harvest index, seeds per pod , days to 50% pod setting, pods per plant, days to 50 % flowering, seed index and biological yield have the significant positive association with the seed yield per plant at both genotypic and phenotypic levels. The path analysis revealed that the harvest index, biological yield, days to 50 % flowering, plant height, pod length and clusters per plant had shown the true relationship with seed yield by establishing the positive correlations and direct effects at both genotypic and phenotypic levels, while branches per plant and days to maturity at genotypic levels and pods per plant and seeds per pod at phenotypic levels.
