The prime objective of any plant breeder is developing new cultivars with high yield. The present investigation aimed at estimating the general combining ability among parents and specific combining ability in hybrids for various yield and related traits in upland cotton. Forty hybrids were obtained by crossing 8 elite lines with 5 selected testers in a Line × Tester fashion. All 40 hybrids, 13 parents along with 3 checks were evaluated under rainfed condition during kharif 2017-18at Agriculture Research Station, Dharwad Farm. Analysis of variance showed significant differences among parents and hybrids for most characters indicating presence of genetic variability. The ratio between variance due to GCA to that of SCA was less than unity for all characters indicating preponderance of non-additive gene effects in the inheritance of characters. Among lines, FLT-36, CPD-462 and among testers, SCS-1061, registered significant positive gca effects for seed cotton yield. Cross CPD-462 × SCS-1061 recorded high seed cotton yield with positive significant sca effects.
