The 8029AB line is a dominant genic male sterility (DGMS) two-type line in L., which can be used in a three-line approach for the seed production of rapeseed hybrids. Genetic analyses have demonstrated that the sterility of 8029A is controlled by a single dominant nuclear gene () interacting with one recessive gene (). Six pairs of penta-primer amplification refractory mutation system (PARMS) markers were designed according to the sequence of , and . Two pairs of these PARMS markers were successfully identified and validated. The PARMS markers MS5-1Fc/MS5-1Ft/MS5-1R12 could distinguish from /, and the PARMS markers MS5-2Ft/MS5-2Fa/MS5-1R12 could genotype and /. The combination of these two pairs of PARMS markers could be used to identify the presence or absence of effectively. Consequently, marker-assisted selection can be carried out in the early generation to shorten the breeding period and improve the breeding efficiency.
8029AB系是甘蓝型油菜中的显性核不育两型系,可用于油菜杂交种的三系制种。遗传分析表明,8029A的不育性受一个显性核基因()与一个隐性基因()互作控制。根据、和的序列设计了6对五引物扩增阻滞突变系统(PARMS)标记。其中两对PARMS标记已成功鉴定和验证。PARMS标记MS5 - 1Fc/MS5 - 1Ft/MS5 - 1R12可区分与/,PARMS标记MS5 - 2Ft/MS5 - 2Fa/MS5 - 1R12可对和/进行基因分型。这两对PARMS标记组合可有效鉴定的存在与否。因此,可在早代进行分子标记辅助选择,以缩短育种周期,提高育种效率。
