Estimation of genetic variability in blackgram [Vigna mungo(L.) Hepper]

Abstract

An investigation was carried out during kharif, 2018 in Randomized Block Design to estimate the variability parameters in blackgram using thirty five genotypes including two checks viz., Pratap Urd-1 and Pant Urd-31. The results of ANOVA showed that the genotypes varied significantly for all the traits. The high GCV and PCV estimates were recorded for seed yield per plant, plant height, harvest index and 100-seed weight. High magnitude of heritability combined with the high genetic gain was found fortraits viz., plant height, the number of pods per cluster and 100-seed weight. Therefore, direct selection for the traits like, plant height, harvest index, 100-seed weight and the number of pods per cluster would be useful for increasing seed yield in blackgram.
