The present study was conducted to assess the genetic variability, heritability and genetic advance in four F3 populations for 11 quantitative traits including seed yield per plant. The material comprised of four F3 generations derived from crosses viz., Meha x Pusa Vishal, Meha x GJM-1006, Meha x GM-4 and Meha x GJM-1008 comprising of 23, 20, 22 and 15 progenies, respectively. These progenies were laid out in separate Randomized Block Design trials with 3 replications along with respective parents, population size being 20 plants per progeny per row. Low to moderate GCV and PCV values were observed for days to 50 % flowering, days to maturity, plant height, primary branches per plant, seeds per pod and 100 seed weight indicated limited scope for improvement of these traits. While, GCV and PCV estimates were moderate to high for pods per plant, seed yield per plant, clusters per plant, straw yield per plant and harvest index suggesting that there is greater scope for improvement of these characters. High heritability estimates coupled with high genetic advance were observed for pods per plant, clusters per plant, seed yield per plant, straw yield per plant and harvest index coupled with high genetic advance as per cent mean suggested the importance of additive genetic variance for these traits. Hence, priority should be given to these traits in selection to obtain better gains. The F3 population of crosses viz., Meha x 1006 and Meha x GJM-1008 needs to be handled under different selection schemes for improving productivity as they depicted high heritability along with high genetic advance as per cent mean for most of the traits.
