V. BALInterspecific hybridization was carried out between cultivated sunflower CMS lines (2453-A, 2517-A, 6388-A, 9661-A) and wild Helianthus annuus accession 9, 17 and H. argophyllus (34, 35) from collection of USDA, America. The 4 CMS lines and 4 wild sunflower genotypes were crossed to obtain 16 combinations in the field conditions of Agriculture Research Station, Bursa Uludağ University located southern Marmara region, Türkiye in 2019. Hybrid plants were produced using classical breeding and immature embryo methods. The degree of crossability performance of genotypes were determined. The F1 progenies were characterized from morphological and phenological point of view.
As a result of hybridizations, the filled seed ratio values varied between 0% and 68.7% in the field conditions. The highest number of filled seeds was obtained from the combination of 2517-A x H. annuus (17) (68.7%). No seed was obtained from combinations of 2517-A x H. annuus (9), 6388-A x H. argophyllus (34), 6388-A x H. argophyllus (35), 9661-A x H. annuus (9), 9661-A x H. annuus (17) (%0). While significant differences were observed in most of the morphological characters among Fı plants, there were generally no major differences in terms of phenological characters.KAN AGRV.
