Interspecific hybridization was done between cultivated sunflower H.annuus L. and the perennial species H.ciliaris, accession М-092. The embryo cultivation method was used for successful performance of the crosses. Crosses were realized between this species and sterile lines 2607 and НА-300. Different morphological characters were investigated. As a result of self-pollination and selection, hybrid materials in both F1 and F2 were obtained, and in advanced generations as well. Morphological, phenological and biochemical studies were carried out. Some of the progenies possessed higher seed oil content. Four lines among the selected, combined complete resistance to the pathogens of downy mildew and broomrape. These were the lines 1131/н, 1135/н, 1145/н, 1171/р, 1161/p and 1151/р

• The height of the new lines developed was reduced in comparison to parental line 2607;
• The new lines have higher content of oil in seeds in comparison to the parental forms;
• A part of the breeding lines have higher content of oleic acid in oil, and line 1171/р is with higher linoleic acid content;
• The hybrid combinations of the new lines demonstrated stable values above the mean standard by the indices seed yield and oil yield during the three-year testing.
