Sixty two progenies of backcross (BC₁ F₁) population, (KC 3 X Suvin) X KC 3, developed by crossing Gossypium hirsutum L. var. KC 3 and Gossypium barbadense L. var. Suvin, were subjected to estimate genetic variability, heritability and genetic advance. Phenotypic coefficient of variation was found to be greater than genotypic coefficient of variation for all the characters, indicating environmental influence on these traits. High phenotypic and genotypic coefficient of variation estimates were obtained for seed cotton yield, number of bolls per plant and number of sympodia per plant indicating presence of sufficient genetic variability for these characters, and hence they are amenable for selection. High heritability, coupled with high genetic advance was observed for boll weight and lint index, indicating additive gene effects. The directional selection for these traits could be effective for desired genetic improvement.
