| Abstract: | The presence of the Rf1 gene (pollen fertility restorer of CMS PET1) in genotypes of most restorer lines is confirmed by molecular and hybridological
analysis methods. Molecular markers of the Rf1 locus are identified for the first time in genotypes of autofertile lines of the collection of the Vavilov All-Russian Research
Institute of Plant Industry (VIR) as well as in genomes of perennial and annual wild species of the genus Helianthus. The possibility of introgression of the fertility restorer gene into the genome of the cultivated sunflower during distant
hybridization is shown. |
