摘　　要：为创制杂交油菜新育种材料,利用甘蓝型油菜显性核不育轮回群体遗传规律,不断向轮回群体中添加双低或黄籽双低常规品系与显性核不育株进行杂交,利用其保持原理全部进行混合繁殖,充实基因库以保证不断选育出新的隐性核不育恢复系,品质分析后选优株进行套袋自交,经6年7代成功选育出黄籽双低高油分恢复系YD57R。该恢复系芥酸含量0.77%,硫苷含量22.26μmol/g饼,含油量48.23%。The recessive genic male sterility restorer lines can be bred from the mixed reproduction offspring constantly after the recurrent populations were crossed with conventional lines with double-low or yellow seed and double-low continuously based on the genetic regularity of dominant genetic sterility recurrent selection population in Brassica napus to innovate breeding materials for hybrid rape. Restorer line YD57R with yellow seed and double-low was bred from the selected plants determined by quality analysis after selling for 6-7 generations. The erucic acid, Glucosinolate and oil content of restorer line YD57R is 0.77%, 22.26 μmol/g cake and 48.23% respectively.
