9012AB, a recessive genic male sterility (RGMS) line derived from spontaneous mutation in Brassica napus , has been playing an important role in rapeseed hybrid production in China. The male sterility of 9012AB is controlled by two recessive genes (ms3 and ms4) interacting with one recessive epistatic suppressor gene (esp). The objective of this study was to develop PCR-based markers tightly linked to the esp gene and construct a high-resolution map surrounding the esp gene. From the survey of 512 AFLP primer combinations, 3 tightly linked AFLP markers were obtained and successfully converted to codominant or dominant SCAR markers. Furthermore, a codominant SSR marker (Ra2G08) associated with the esp gene was identified through genetic map integration. For fine mapping of the esp gene, these PCR-based markers were analyzed in a large BC1 population of 2545 plants. The esp gene was then genetically restricted to a region of 1.03 cM, 0.35 cM from SSR marker Ra2G08 and 0.68 cM from SCAR marker WSC6. The SCAR marker WSC5 co-segregated with the target gene. These results lay a solid foundation for map-based cloning of esp and will facilitate the selection of RGMS lines and their temporary maintainers.

One of the prior directions in spring rapeseed breeding is development of heterotic hybrids. Seed growing of the most hybrids F1 used in production are often carried out by two types of cytoplasmic male sterility, they are polima and ogura. At the Lipetsk Rapeseed Research Institute, fertility restorers on sterile cytoplasm were made and estimated for the main valuable traits. The purpose of the research was to develop effective restorers, which are necessary for obtaining of highly productive hybrids on the Polima type cytoplasmic male sterility (CMS). The object of research was 56 varieties of Brassica napus L., which were selected in 2013. It is noted that hybrids F1 were more productive than the parental forms and the standards (the varieties Ratnik and Rif). The restorer line LHR-1 is of practical interest for the development of hybrids on the Polima CMS.
