The present study was conducted at Regional Agricultural Research Station (RARS) Lam Farm to analyze the phenotypic and genotypic coefficients of variation, heritability and genetic advance as per cent of mean during kharif, 2013–14. The analysis of variance indicated that significant variation present among the accessions of the Egyptian cotton for all the traits under study. The highest genotypic (GCV) and phenotypic coefficient of variation (PCV) were exhibited by the number of monopodia plant−1, lint yield plant−1 and seed cotton yield plant−1. PCV had similar trend as GCV. High heritability coupled with high genetic advance as per cent of mean was observed for number of monopodia plant−1, number of sympodia plant−1, number of bolls plant−1, lint index, seed cotton yield plant−1 and lint yield plant−1. The combination of the high heritability and high genetic advance as per cent of mean provide opportunity for improvement of these traits by simple selection process.
