Broomrape is the major issue of sunflower production in Serbia. Since its first occurrence, the species of Orobanche cumana had been responsible for considerable yield loss in some areas. In Serbia broomrape is present in the Vojvodina Province. Distribution and virulence groups of parasite are constantly monitored. Only two distinct broomrape populations currently exist in this part of country. Race B is dominant in the south of the Vojvodina Province and race E in the north. During 2008, sets of 8 commercial hybrids with different broomrape resistance genes were sown in regions with sunflower production. Hybrids were sown on 34 different locations. Presence of broomrape was confirmed on 6 sites. Occurrence of parasitic plants was not detected on cultivars resistant to race E. Sunflower fields in regions where broomrape was not previously detected, were surveyed. The survey revealed occurrence of broomrapes in new regions. Infested areas are located in Bor county near the state border with Romania and Bulgaria.
