Abstract

Eighteen genotypes of Brassica napus were crossed to a cytoplasmic male sterile (CMS) line of B. napus BO15 carrying B. tournefortu cytoplasm ('tour' cytoplasm). Fourteen genotypes were found to be stable maintainers 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 F[SUB1] and F[SUB2] progenies of (CMS) BO15 × 'Mangun' and (CMS) BO15 × 'Yudal' showed that fertility restoration is controlled by a single dominant gene.The availability of a number of stable maintainer lines and the simple inheritance pattern of fertility restorer gene makes 'tour' CMS a useful system for hybrid seed production in rapeseed.
