Abstract: Different morphological and fiber traits of upland cotton (Gossypium hirsutum L.) were studied for the presence of genetic variability and effects due to GCA and SCA. The objective was to determine the genetic variability and the effects due to GCA and SCA. In this experiment, a set of twelve genotypes, i.e., FH-119, MNH-888, CRSM-38, Bt-23, Bt-222, Bt-2333, FH-161 and FH-174, were selected as male parents and four genotypes, i.e., SB-149, FH-153, VH-144 and NIAB-111, as female parents. The genotypes were crossed, using North Carolina Mating design-II (NCM-II), to develop thirty two crosses. The seeds of 12 parents and their 32 F0 hybrids were sown in the university research area, using randomized complete block design (RCBD) under three replications. The data of quality parameters and morphological parameters, i.e., plant height, number of monopodia, number of sympodia, number of bolls per plant, seed index, fiber length, fiber strength, fiber fineness and fiber uniformity, were collected. The analysis of variance demonstrated that all the parents and their F1 hybrids differed significantly from each other for all the parameters studied except fiber fineness.
