Presence of genes for restoration of male sterile PET-1
cytoplasm and mode of their action have been determined
in 8 populations of wild Helianthus annuus and one H.
petiolaris ssp. petiolaris Nutt. population. One dominant
gene was found to be present in three wild H. annuus
populations (ANN-2159, ANN -221 3 and ANN-2226) and
the populations of Helianthus petiolaris ssp. petiolaris Nutt.
(PET-2167). The remaining 5 populations (ANN-2143,
ANN-2172, ANN-2173, ANN-2199 and ANN-2229) had two
complementary dominant genes.
