Genetic variability studies in Blackgram (Vigna mungo (L.) Hepper)

Abstract

In the present investigation, twelve characters including quantitative and qualitative were evaluated in 29 genotypes of blackgram during Kharif 2016 to assess the genetic variability. The genotypes differed significantly for all the characters studied. The highest GCV recorded for seed yield per plant, biological yield per plant, number of pods per plant and number of branches per plant. High heritability was recorded for number of branches per plant, 100 seed weight, plant height and number of pods per plant. The highest genetic advance as percent of mean was recorded for seed yield per plant, number of branches per plant, number of pods per plant and biological yield per plant. High heritability coupled with high genetic advance was observed for number of branches per plant and number of pods per plant indicating that these characters can be improved by selection.
