description Twenty four lines were crossed with two testers in an L x T mating design to estimate the combining ability for seed yield insunflower. Non-additive genetic variance played a preponderant role in the inheritance of all the characters studied viz., daysto 50 % flowering, days to maturity, plant height, head diameter, volume weight, hundred seed weight and seed yield perplant. The lines 27, 436 and tester 234A can be considered as superior parents in the present study as they recorded high per seperformance with positively significant general combining ability effect for seed yield/plant. Among the 48 hybrids evaluated,crosses viz., 234A x 436, 234A x 440 and 234A x 235 were considered as superior hybrids as they recorded high per seperformance and significant sca effect for seed yield/plant.
