The present investigation was undertaken to study the combining ability and gene action in sunflower. Five CMS lines and nine restorers were included as parental material. CMS 10A was a good general combiner for days to 50% flowering, days to maturity, head diameter, 100 seed weight, seed yield/plant, volume weight and seed filling. Similarly, CMS 519A and CMS 62A were good general combiners for seed yield and component traits. Among the testers, TSG-04 was a good general combiner for days to 50% flowering, days to maturity, plant height and 100 seed weight. Out of 45 hybrids, five hybrids viz., CMS 62A x SCG-04, CMS 234-1017A x TSG-327, CMS 234-1017A x TSG-111 and CMS SUN-35-519A x TSG-289 exhibited significant desirable sca effect for seed yield and component traits.
