A breeding method for Ogura CMS restorer line independent of restorer source in <i>Brassica napus</i>.

ABSTRACT: The Ogura cytoplasmic male sterility (CMS) line of Brassica napus has gained significant attention for its use in harnessing heterosis. It remains unaffected by temperature and environment and is thorough and stable. The Ogura cytoplasmic restorer line of Brassica napus is derived from the distant hybridization of Raphanus sativus L. and B. napus, but it carried a large number of radish fragments into Brassica napus, because there is no homologous allele of the restorer gene in B. napus, transferring it becomes challenging. In this study, the double haploid induction line in B. napus was used as the male parent for hybridization with the Ogura CMS of B. napus. Surprisingly, fertile plants appeared in the offspring.
