The present investigation aimed to study genetic variability generated from the Gulyal white X Maruti cross in F3 and F4 generation to make effective selections for improving productivity. The study indicated that the higher magnitude of variability were recorded in F3 and F4 generation for 50 per cent flowering, number of secondary branches, number of seeds per pod, number of pod per plant, seeds yield per plant and seed yield (Kg/ha) and moderate variability observed in pod bearing length and test weight (gm). The higher heritability and genetic advance per mean were recorded in F3 and F4 generation for 50 per cent flowering, number of secondary branches, number of seeds per pod, number of pod per plant, seeds yield per plant and seed yield (Kg/ha) that implicate additive gene action in inheritance of these traits thus phenotypic selection would be effective in yield improvement .
