Twenty nine genotypes of cotton (19 Gossypium hirsutum and 10 G. barbadense) were estimated for genetic variability. High heritability was recorded by bundle strength. Seed cotton yield per plant and number of bolls per plant combined high heritability and genetic advance as percentage of mean. Bundle strength, 2.5 per cent span length, fibre fineness and seed oil content registered high heritability and low genetic advance as percentage of mean.
