Abstract: Interspecific hybridization was carried out between sterile analogues of cultivated sunflower lines with normal cytoplasm and wild annual Helianthus bolanderi accession E-009 from collection of DAIGeneral Toshevo. Hybrid plants were produced using classical breeding methods and the biotechnological method embryo rescue. The degree of crossability and the inheritance of some morphological traits were determined. The obtained F1 progenies were characterized from morphological and phytopathological point of view. Hybrid forms distinguished with resistance to stem canker, phoma and downy mildew were obtained. The hybrid plants, carriers of Rf genes for CMS Pet 1, could be used in sunflower breeding programs for developing restorer lines.
