The research was carried out to assess the nature and magnitude of genetic variability, along with proportions of heritability and genetic advance among 14 crosses and ten parents by considering 11 yield and its related traits in blackgram. The investigation was undertaken in the Experimental Farm of Department of Genetics and Plant Breeding, College of Agriculture, CSKHPKV, Palampur (H.P.) during Kharif 2018 and 2019 in Randomized Complete Block Design over three replications. Analysis of Variance revealed significant differences among the genotypes for all the traits in both the generations. High PCV and GCV was recorded for biological yield per plant (g), seed yield per plant (g) and harvest index (%). High heritability along with high genetic advance was recorded for pods per plant, biological yield per plant, seed yield per plant and harvest index in both the generations indicating the preponderance of additive gene action to develop desirable and stable genotypes during breeding programme.

The investigation was undertaken in the Experimental Farm of Department of Genetics and Plant Breeding, College of Agriculture, CSKHPKV, Palampur (H.P.) during Kharif 2018 and 2019 in Randomized Complete Block Design over three replications. Analysis of Variance revealed significant differences among the genotypes for all the traits in both the generations. High PCV and GCV was recorded for biological yield per plant (g), seed yield per plant (g) and harvest index (%). High heritability along with high genetic advance was recorded for pods per plant, biological yield per plant, seed yield per plant and harvest index in both the generations indicating the preponderance of additive gene action to develop desirable and stable genotypes during breeding programme.
