The present experiment involved four CMS line and six tester crossed in a line x tester fashion to estimate the combining ability for seed yield and yield contributing traits in sunflower. The resulting 24 hybrids were evaluated in two replications of RBD design. CMS-234A and CMS-243A exhibited good GCA for day to 50% flowering, hull content and oil content. From testers, EC-601951R and 99RT were with GCA effect for 50% flowering, days to maturity, plant height, hull content, head diameter, 100 seed weight, seed yield/plant. Cross combinations, CMS- 243A x 99RT and CMS-17A x EC-279309 recorded good SCA effect for maturity, oil content and seed yield. Good SCA for seed filling and seed yield/plant was reported in PET-89-1A x RHA-1-1 combination.
