Abstract
Eighteen genotypes of Brassica napus were crossed to a cytoplasmic mal e sterile (CMS) line of B. napus BO15 carrying B. tournefortii cytopla sm ('tour' cytoplasm). Fourteen genotypes were found to be stable main tainers of the 'tour' CMS. Of the remaining four genotypes, GSL-1 and 'Asahi-natane' were found to be heterozygous and 'Mangun' and 'Yudal' were homozygous for the restorer gene. Analysis of the F1 and F2 proge nies of (CMS) BO15 x 'Mangun' and (CMS) BO15 x 'Yudal' showed that fer tility restoration is controlled by a single dominant gene. The availa bility of a number of stable maintainer lines and the simple inheritan ce pattern of fertility restorer gene makes 'tour' CMS a useful system for hybrid seed production in rapeseed.
