Among the factors that cause significant yield losses in sunflower is the infestation with broomrape. The parasite affects a number of yield components, namely plant height, head diameter, number of seeds per head, lipid and protein content in seeds, oil quality and quantity, etc. The present study carried out in 2012-2013 dealt with the influence of broomrape on oil yield and oleic acid content in various sunflower genotypes (commercial and experimental hybrids) cultivated in 6 distinct localities on uninfested and infested fields where the degree of broomrape attack varied from 0 to 70%. Oil content in the hybrids Favorit, Performer and LG 5661 was affected to some extent by the degree of parasite attack. The difference between the oil content in sunflower seeds from the uninfested/ poorly infested fields and those from the heavily infested fields was about 2-3% (Favorit, LG 5661) and 5-6% (Performer). The content of oleic acid in the hybrids Sandrina, HS 5034, HS 3045, with mean resistance and LG-3, Favorit and HS 3655, with a high resistance to broomrape, varies mainly in relation to the genotype and cultivation conditions, and less depends on the attack of the parasite.
