The present investigation was carried out with a view to study the magnitude of variability, correlation and path analysis involving 41 genotypes in Blackgram during Zaid-2019 in randomized block design with three replications and a check. The analysis of variance indicated the existence of significant genotypic differences among the genotypes for the yield and its component characters. High GCV and PCV values were not observed in these genotypes whereas moderate GCV and PCV values were recorded for Seed index. High heritability coupled with high genetic advance as percent of mean was observed for days to maturity indicating the role of additive genes in the inheritance of these traits and hence these characters would be improved through simple phenotypic selection. Character association studies revealed significant positive association of seed yield per plant with number of pods per plant and number of seeds per pod. The path coefficient analysis indicated that selection for number of clusters per plant, number of pods per plant and number of seeds per pod would directly increase seed yield
