The success of most crop improvement programs depends on variability and heritability of desirable traits. An investigation was carried out during kharif 2016 at Botanical garden, University of Agricultural Sciences, Dharwad, India to assess the extent of variability generated by hybridization and to estimate the heritability and genetic advance as percent of mean for seed cotton yield and its component traits in F2 generation of cross QTP 16 × ASa 151. The segregating population thus obtained was evaluated for eight quantitative traits. A wide range was observed for traits plant height, number of sympodia per plant, number of bolls per plant and seed cotton yield per plant. High phenotypic coefficient of variation and genotypic coefficient of variation were recorded for traits number of sympodia per plant, number of bolls per plant and seed cotton yield per plant. High heritability coupled with high genetic advances was recorded for all traits under consideration except for traits ginning outturn, seed index and seed cotton yield per plant in the F2 population. Seed cotton yield per plant recorded moderate heritability couple with high genetic advance as per cent of mean.
