Abstract: Fifty genotypes of black gram were evaluated during rabi 2018-19 at ARS, Ghantasala, Krishna district, Andhra Pradesh in RBD with three replications under rice fallow situation. The phenotypic coefficient of variation was found superior than the genotypic coefficient of variation for all traits studied, showing that the variation is not only genetic but also influenced by growing environments in the expression of the traits. The genotypes were highly variable for No. of branches per plant, No. of clusters per plant, No. of pods per plant, seed yield per plant, total biomass per plant, harvest index, No. of nodules per plant and leaf area index. Broad sense heritability was higher for all the traits except days to maturity, plant height, 100 seed weight and pod length. High heritability coupled with high genetic advance as per cent of mean was observed for No. of branches per plant, No. of clusters per plant, No. of pods per plant, No. of seeds per pod, seed yield per plant, specific leaf weight, leaf nitrogen content, total biomass per plant, harvest index, No. of nodules per plant, weight of nodules, leaf area index and specific leaf area.
