Genetic Variability, Correlation and Path Coefficient Analysis of Seed Yield Components in Green Gram

The present investigation aimed to study genetic variability, correlation among the morphological and yield components with their direct and indirect effects on seed yield those generated from the cross LM 192 × MDU 3465 in F₂ and F₃ generation to enhance selection efficiency for yield improvement. The study indicated that higher the magnitude of variability was recorded inthe F₂ and F₃ generation for plant height, primary branches per plant, cluster per plant, pods per plant, pods per cluster, pod yield per plant, seed yield per plant and threshing percentage. Higher heritability along with genetic advance as per cent of the mean were recorded in F₂ and F₃ generation for all the traits studied except for days to first flowering that implicate additive gene action in inheritance of these traits thus phenotypic selection would be effective in yield improvement. Phenotypic coefficient of variation was slightly higher in magnitude than the genotypic coefficient of variation. Number of pods per plant, pod yield per plant and threshing percentage had shown positive and significant correlation along with their high positive direct effect with seed yield, suggesting that these parameters may be considered as prime traits during the course of selection to have the higher potential of yield in case of green gram.
