Populations of wild sunflower species collected from the north-western United States, Central Great Plains and Great Lakes region of the United States have been analyzed for the presence of genes for restoration of PET-1 male sterile cytoplasm. The number of genes present and modes of their action have been determined in nine populations of which eight belonged to wild Helianthus annuus and one to Helianthus arophyllus. When crossing these populations to a sterile line L-1, all plants in the F1 generation were fertile. It is an indication that the populations were homozygous for the gene for restoration of the male sterile cytoplasm. The obtained results showed that six populations (ANN-1975, ANN-2101, ANN-2148, ANN-2170, ANN-2206 and Arg-6) had one dominant gene and three populations (ANN-1981, ANN-2157 and ANN-2168) had two complementary dominant genes for restoration of PET-1 male sterile cytoplasm.
