Abstract:
The research was conducted on Black gram (Vigna mungo (L)) genotypes during the Kharif season of 2022 at the New Upland Research Cum Instructional Farm, Lamker, S.G. College of Agriculture and Research Station, Kumhrawand, Jagdalpur, IGKV, Raipur (Chhattisgarh), in randomized block design. The research focused on studying the qualitative and quantitative traits of black gram in order to characterize and evaluate the variability among 44 elite genotypes of black gram. The analysis of variance showed highly significant differences among the 44 genotypes for each trait. The variability analysis revealed that for the parameters plant height (cm), number of pods per plant and terminal leaflet width high estimates of GCV and PCV were observed, showing the importance of selection for improving output. (Indicating the genetic improvement of the traits through selection). The high heritability along with high genetic advance as percent of mean was recorded on the characters plant height, number of branches per plant, number of pods per plant, terminal leaflet length, terminal leaflet width, number of pods per cluster and seed yield. The wide range of these traits indicated the presence of sufficient variability in breeding population and also indicated better scope for improvement for mutant lines of above characters. The genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) values showed a lot of variability exists among phenotypic as well as genotypic level and better chance for improvement is possible by selection. High heritability shows that the character is governed by additive gene action for the improvement of this character selection would be rewarding.
