[Progresses of study on the DNA locus related to cytoplasmic male sterility and restorer gene for fertility in rapeseed].

CMS in rapeseed is of tremendous importance in its commercial application in hybrid seed production. This review focuses on the progresses of study on CMS in rapeseed from four aspects: (1) the mitochondrial DNA locus found to be associated with CMS, (2) the effects of restorer gene for fertility on the expression of the locus associated with CMS, (3) the mapping with molecular marker and (4) cloning of restorer genes of fertility of the CMS in rapeseed. The prospects of further studies on this subject are discussed.
