The aim of this study was to evaluate genetic variability, path and correlation analysis among 187 double cross pyramided lines of blackgram (Vigna mungo L.) with a focus on yield and its related traits. The variability analysis found that PCV was greater than GCV for all attributes indicated that notable influence of the environment on these attributes. Variability analysis revealed that the traits seed yield/plant, number of clusters/plant, number of pods/plant, number of seeds/pod and number of branches/plant which exhibited both high heritability and GAM. This suggests that these traits are governed by additive gene action, making them ideal options for selection to enhance yield in blackgram. The results of path and correlation analysis emphasize the significance of traits like the number of clusters/plant, the number of pods/cluster and the number of pods/plant. These traits are identified as primary selection criteria for increasing yield in urdbean.
