Identification of the resource of cytoplasmic male sterility (CMS) in wild rice always attracts the rice breeders for developing alternative CMS lines.orfH79,a chimeric gene in mitochondrial genome suggested to be related to HL-type CMS of rice.In this report,characterization of the distribution and single nucleotide polymorphism of orfH79 related to Honglian CMS in the genus of Oryza with AA genome were performed.PCR and Southern blot analysis revealed that 8 out of 42 investigated accessions were identified sharing orfH79.
