Genetic characterization of a new radish introgression line carrying the restorer gene for Ogura CMS in Brassica napus.

ABSTRACT: Creating a homologous restorer line for Ogura cytoplasmic male sterility (Ogu-CMS) in Brassica napus is meaningful for the wider application of Ogu-CMS system in rapeseed production. Previously, an independent development of a new Ogu-CMS restorer line (CLR650) was reported locally from crossing between Raphanobrassica (AACCRR, 2n = 56) and B. napus and a new version of Ogu CMS lines CLR6430 derived from CLR650 was characterized in this study. The results showed that the fertility restoration gene in CLR6430 presented a distorted segregation in different segregating populations. However, the majority of somatic cells from roots had a regular chromosome number (2n = 38) and no radish signal covered a whole chromosome was detected using GISH. Thirty-two specific markers derived from the intr
