The research work comprising of genetic variability, heritability and genetic advance study for seed cotton yield and its components in fifteen cotton (Gossypium sp. L.) genotypes was carried out during 2011 at the Plant breeding farm, Annamalai University, Chidambaram. ANOVA test indicated highly significant variation among the genotypes for all the characters. Number of monopodia per plant, days to 50% flower and number of bolls per plant showed high GCV and PCV. While ginning outturn showed comparatively low GCV and PCV. Moderate to high heritability estimates and low to high genetic advance estimates were found for all traits. High heritability resulted for almost all the traits except monopodia per plant and ginning outturn whereas high genetic advance exhibited for most of the traits except sympodia per plant, number of bolls per plant and ginning outturn.
