 ABSTRACT

The present experiment was conducted during kharif-2014-15 to know the genetic variability present among the upland cotton genotypes. The traits viz., boll weight, seed index, lint index and ginning out turn were recorded minimum difference between GCV and PCV values indicated less influence of environment on these traits phenotypic expression. Seed index and lint index exhibited high heritability coupled with high genetic advance as per cent of mean. It means these characters are may be controlled by additive gene action and more responsive to simple direct selection. 

Key words: Upland cotton, Genetic variability, Heritability and GAM.
