Abstract
The present Investigation was carried out to study the genetic variability, coefficient of variance, heritability and genetic advance in American cotton. The material was evaluated in a Randomized Block Design (RBD) with three replications during kharif 2019. In this experiment analysis of variance indicated that significant variation present among the accessions of the upland cotton for all the traits under study. The highest genotypic (GCV) and phenotypic coefficient of variation (PCV) were exhibited by the number of monopodia per plant, number of bolls per plant and boll weight. High heritability with high genetic advance was observed in the boll weight, number of monopodia per plant, number of bolls per plant, seed cotton yield per plant, number of sympodia per plant and lint index. The combination of the high heritability and high genetic advance provide the clear image of the trait in the selection process.
