摘　　要：利用贵州省油菜研究所选育的配合力好双低恢复系0202R作母本，用高油分、高蛋白质含量的942优良株系作父本，进行有性杂交，经过3～5代选育，结合室内品质分析，选育出产量比0202R增产11．78％，品质优良、含油率比0202R高6．32个百分点、配合力强的隐性核不育恢复系017R。其终花期比0202R长6d，植株比0202R高17．1cm，分枝比0202R长3．5cm，以利中后期母本的授粉结实，提高制种产量和质量。017R, a restorer line with low erucic acid, glucosinolate and high oil content, was bred from the cross combination of 0202R （a restorer line with the good combining ability and low erucic acid, glucosinolates content） × 942, a good line with high oil and protein content after 3-5 generations. The yield, oil content and plant height of 017R is 11.78%, 6.32 % and 17.1cm higher than those of 0202R separately. Its flower ending stage and branch length is 6 d and 3.5 cm longer than those of 0202R respectively, which is beneficial to improving seed yield and quality.
