Description Field experiment was conducted to estimate the combining ability and heterotic effects of sunflower hybrids. Twelve lines and six testers were crossed in Line × Tester mating design to generate 72 hybrids during Rabi/ summer 2021, which were further evaluated in Kharif 2022 along with checks at UAS, GKVK, Bengaluru. The cross-combination CMS 335 A × RHA 95 C10 exhibited better per se performance and standard heterosis for seed yield plant-1 and oil content. Further the lines (CMS 17, CMS 335, CMS 597) and the testers (RHA 95C-10, RHA 278) exhibiting desirable combining ability should be preferentially used in hybrid development and testing for commercial exploitation.
