Abstract: Cytoplasmic male sterility(CMS)is an ideal material to study nuclear-cytoplasm interactions, meanwhile it is one of the most effective ways to use heterosis. The researches related to rapeseed CMS in recent years focused on the analysis of structure characteristics and origins of the sterility genes, the mechanism of sterility gene and the restoration of fertility. This paper introduced the current international main types of CMS(pol CMS, nap CMS, kos CMS, ogu CMS and tour CMS)in rapeseed, and also reviewed the research progress of molecular level, including the identification of CMS-associated regions, the possible mechanism of CMS and the localization of restorer genes.

Key words: rapeseed, cytoplasmic male sterility(CMS), restorer gene
