Reciprocal interspecific crosses were made between sunflower (H. annuus L., 2n=34) and the annual species H. praecox sap. hirsute Engleman & Gray (2n=34) using conventional breeding methods. F1, F2 and F3 hybrids and one backcross generation were obtained. The cross compatibility between H.annuus and H. praecox ssp. hirtus showed differences, depending on the direction of the cross. The manifestation of the parental characters in the hybrid material was studied, as well as the resistance of the F1, F2 and BC1 generations to Plasmopara helianthi, Phomopsis helianthi and Orobanche cumana. The seed oil content and fatty-acid composition of the oil in the hybrid progenies were also evaluated. Initial sunflower hybrid material with linoleic type of the seed oil and resistance to downy mildew and broomrape was produced for future breeding programs.
