Abstract: The field experiment was conducted at Main Agriculture Research Station, Raichur during rabi 2016. Three multibranched CMS lines were crossed with fifteen multibranched testers in an L x T mating design and obtained 45 crosses and evaluated along with their parents and checks in simple lattice design with three replications and observations are recorded on 13 different traits. Both additive and non-additive gene action were found to control the expression of the traits under study but predominantly governed by non additive gene action for most of the characters like days to 50 % flowering, days to maturity, head diameter, volume weight, test weight, number of primary branches per plant, seed yield per plant and oil content. CMS 57 Br A, CMS R3 Brown Br A, R-393, DOR R3, and R-8 are found to be the best general combiners. The crosses, R3 Brown Br A x R-8292 and R3 Brown Br A x R-78 for seed yield, 57 Br A x PM-135, R3 and Black Br A x R-630 for oil content has found with high sca values and also recorded highest heterotic effect over check for seed yield and oil content respectively. These identified superior crosses can be further utilized for the development of multibranched hybrids. Key Words: Sunflower, combining ability, gene action, heterosis
