Combining ability analysis for seed cotton yield and yield components was studied in a L x T fashion using seven lines and eight testers of upland cotton. Non-additive gene action was found to be important in the inheritance of all the traits studied. Parents CPD 420, Galama and LK 861 were identified as good general combiners for yield and one or more yield contributing characters, whereas the crosses NA 1325 x L 604, AKH 9331 x HAG 1055, CPD 420 x JK 344 and NA 1325 x 4084 recorded high specific combining ability effects for yield and yield contributing characters. Aforementioned parents and crosses could be utilized for further selection of high yield.
