To breed a restorer line with high combining ability, high recuperability, excellent quality and good comprehensive characters, the sexual hybridization was studied between the female parent and the male parent through double-cross breeding. The female parent was the double low conventional material with high combining ability and introduced from Shanghai while the male parent was 8264R, a recessive GMS restorer line with yellow seed, low erucic acid, low gluecosinolate and high oil content through double-cross breeding. The results showed that the combining ability of newly bred double-low recessive GMS restorer line was better and its quality was equal to 8264R. The average erucic acid content was 0. 41%, the average glucosinolate content was 23, 68 μmol/g cakes and the average oil content was 41.3%.%为了选育配合力高、恢复力强、品质优良和综合性状好的恢复系,采用复式杂交选育,以上海引进配合力好的双低常规材料作母本,与通过复式杂交选育的隐性核不育黄籽高油分双低恢复系8264R作父本进行有性杂交研究.结果表明:选育出的隐性核不育双低恢复系配合力更好,品质与8264R相当.其平均芥酸含量为0.41％,平均硫甙含量为23.68 μmol/g饼,平均含油量为41.3％.
