Promising Lines as a Result from Interspecific Hybridization between Cultivated Sunflower (Helianthus annuus L.) and the Perennial Species Helianthus ciliaris

Abstract

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
