The results on resistance to broomrape (Orobanche cumana Wallr.) of sunflower hybrids created according to the incomplete 8×8 diallel crossing design are presented. Race F was the most virulent race in the studied broomrape population. There were significant additive and dominant components in the trait regulation. It was found that dominant alleles we responsible for fewer nodules per plant. The best lines in terms of general and specific combining abilities and lines - donors of resistance to broomrape were identified.
