Molecular mapping of the Rf1 gene restoring pollen fertility in PET1-based F1 hybrids in sunflower (Helianthus annuus L.)

Phenotype, chromosomes pairing and pollen vitality were compared between parental populations and F1 hybrids of interspecific cross between Helianthus annuus L. and cultivated sunflower. The investigation of the simple sequence repeats (SSR) polymorphism was also used to test the hybrid nature of F1 populations. The phenotypic traits of F1 hybrid plants were either closer to the wild species or intermediate. Irregular chromosome pairing was found in only 0 to 10% of meiocytes in the meiosis of F1 hybrid plants. Interspecific crosses were confirmed with SSR markers in all hybrid combinations. Alleles that were not present in parental DNA were frequently observed in F1 hybrids. That is additional evidence that those hybrid combinations were not produced by self-fertilization. The results suggest that SSR markers can be efficiently used for the F1 hybrid characterization in crosses between closely related species, in which, the changes of phenotype, meiosis and pollen vitality are not always significant.

Combining Abilities

Combining abilities for plant height and head diameter of ten sterile Alines, three restorers - RF lines and their (10x3) F1-hybrids were examined by line x tester method. Significant differences were found between A-lines, RFlines (testers) and their hybrids. The highest mean for plant height had line MIA- 57 (198.17 cm) and hybrid combination MG-MI-1 x MI-A-57 (239 cm), and the lowest mean had line PL-DI-13 (79.67 cm) and hybrid MG-MI-4 x PL-DI-13 (152.67 cm). Line PL-DI-52 (24.47 cm) and hybrid MG-MI-4 x MI-A-57 (25.37 cm) had the highest mean for head diameter, and the lowest mean was determined in line PL-DI-44 (13.60 cm) and hybrid MG-MI-2 x PL-DI-15 (17.90 cm). Lines with the best general combining abilities were PL-DI-13 for plant height and MI-A-57 for head diameter. Hybrids with the best specific combining abilities were MG-MI-2 x PL-DI-15 for plant height and MG-MI-1 x PL-DI-15 for head diameter.
