Broomrape (Orobanche cumana Wallr.) is an important parasite in sunflower crop in Europe, some Asian countries and Australia (Vranceanu, 2000). The parasite has spread in sunflower crop from south Russia and Ukraine. In Romania this was identified for the first time in 1940-1941 year by Savulescu cited by Dumitru and Sesan (1988) the most infested area being in central and south Moldavia, south Dobrogea and eastern Baragan. The negative impact of broomrape on sunflower could be found on the cultivated as well as on wild sunflower. For broomrape controlling there have been created resistant sunflower hybrids to different races of the parasite. This paper presents the results obtained by testing sunflower differential set for broomrape races A to F as well as some commercial hybrids for races more virulent than F. Also, we tested a set of sunflower genotypes, for studying their behavior, regarding the resistance to the parasite, in 2019 and 2020 years. We found that in Braila area there are present all races of the parasite which have been identified up to now in sunflower crop in Romania.
