SUMMARY The objectives of this study were to determine self-fertility and restoration capability of cytoplasmic male fertility of some wild sunflower genotypes. The evaluated genotypes were Helianthus petiolaris spp. petiolaris (E-142), Helianthusneglectus (E-017) and Helianthus annuus (E-060, E-173, E-174 and E-175). For hybridization, the female inbred line 2453-A was used. Results showed that self fertility ratios of wild sunflower genotypes varied between 22.4 and 66.1%. The highest level of self fertility was observed in Helianthus petiolaris spp. petiolaris (E-142), while Helianthus neglectus had the lowest values. The E-060 and E-174 genotypes did not restore cytoplasmic male sterility in the hybrids tested.
