An estimate of the extent of variability available in a crop could be of immense value to the breeder to efficiently design the breeding procedure for crop improvement. Success of any crop improvement program essentially depends upon the nature and magnitude of the genetic variability present in the crop. An investigation was carried out among the progenies of nine crosses of green gram (Vigna radiata L.) in F2 and F3 generations, to study the variability and genetic parameters. Extent of mean, variability, heritability and genetic advance as percent of mean were worked out for yield and yield attributing traits. In the present investigation, cross ML 1451 x VBN 2 registered higher mean values for number of primary branches, pod length and hundred seed weight in both F2 and F3 generations and for number of pods and yield per plant in F3. Among the segregating generations of the crosses, PUSA 0672 x VBN 2 was found to be of early flowering type. High heritability coupled with high genetic advance as per cent of mean in both generations was recorded by F2 and F3 populations of ML 1451 x VBN 2 for the characters number of primary branches, number of pods, hundred seed weight and yield per plant and for number of seeds per pod in F2 and plant height in F3 generation only. Thus, these two crosses were suggested for advancement of generations and selection.
