Twenty-five blackgram genotypes including two local checks were evaluated during kharif and summer seasons across three locations to estimate genetic variability for yield and its component traits by using pooled analysis of variance. Mean, phenotypic coefficient of variation (PCV), genotypic coefficient of variation (GCV), broad sense heritability (h2), genetic advance (GA) and genetic advance as per cent of mean (GAM) were estimated to elicit information on variability parameters of 10 quantitative traits. The pooled analysis of variance indicated significant differences among the genotypes evaluated for all traits except for pod length and number of seeds per pod. The high variability (phenotypic and genotypic) was observed for number of pods per plant, number of clusters per plant, seed yield and number of branches per plant. High heritability was observed for days to 50 per cent flowering, days to maturity, plant height, number clusters per plant and seed yield. High heritability and genetic advance was exhibited by seed yield and number of branches per plant indicating that these traits could easily be improved through phenotypic selection.
