Moth bean [Vigna aconitifolia (Jacq.)] is an important leguminous crop known for its drought resistance and nutritional value.
This study evaluates genetic variability, Heritabilit correlation among 20 elite moth bean genotypes. Conducted at ITM University, Gwalior, the experiment followed a randomized block design (RBD) with three replications. Eleven quantitative traits, including seed yield, harvest index and protein content, were analyzed.
Indicating involvement of environmental effects, phenotypic coefficients of variation (PCV) were consistently higher than genotypic coefficients of variation (GCV). The highest GCV was observed for harvest index (27.99%), seed yield per plant (26.16%) and number of pods per plant (21.76%), suggesting high genetic variability. Heritability in broad sense was very high for number of seeds per pod (98.82%), harvest index (98.80%), number of pods per plant (98.40%) and seed yield (96.84%). Genetic advance as per cent of mean was highest for harvest index (57.32%), seed yield per plant (53.03%) and number of pods per plant (44.04%), indicating the potential for substantial improvement through selection. Correlation analysis revealed strong positive associations between seed yield and harvest index (r=0.958) and number of pods per plant (r = 0.854) at genotypic level, suggesting these as key contributors to yield enhancement. These findings provide valuable insights for genetic improvement and breeding strategies aimed at enhancing moth bean productivity.
