Eleven F/F,M, urdbean progenies comprising four irradiated single, four single, two three-way and one double cross progenies generated by involving parents for seed index and pods per plant were compared for genetic variability parameters. Higher range was observed for plant height, pods per plant, 100-seed weight and seed yield per plant in the irradiated single cross progenies. Three-way and double cross progenies had higher values for pod length and number of seeds per pod. Variability generated by irradiation of single cross had supplemented hybridization for number of clusters per plant and pod length. Hybridization involving more than two parents resulted in sufficient variability for remaining traits under study. High heritability value (>90%) was estimated for 100- seed weight in all the progenies wherever large seeded parent was used as a donor. Creation of desirable variability depended on the trait under consideration, selection of parental lines and methodology advocated generating variability.
