ABSTRACT
The investigation pertaining to heritability and genetic advance in cotton genotypes for some quantitative and qualitative traits were undertaken. The results indicated highly significant differences among the parents and F1 crosses for all the traits. Plant height and seed cotton yield per plant displayed moderate to higher estimates of heritability and genetic advance which is indicative of additive with partial dominance type of gene action suggesting the feasibility of selection in the early generation, while bolls per plant, boll weight and staple length exhibited moderate to high heritability and low genetic advance which indicated over dominance type of gene action thereby revealing that selection might be useful if delayed. The traits monopodia and sympodia per plant gave low to moderate heritability and low genetic advance but the trait micronaire value manifested high heritability coupled with low genetic advance.
