通过品种间杂交，采取系谱法或系谱集团法选择定向培育；把田间选择与室内选择密切结合，贯芽始终地加强产量性状和抗（耐）病性选择；并把含油量与双低性状放在同等地位，始于中世代（选择标准随世代增加而提高）进行选择。采取选育、鉴定、示范、繁殖、推广有机结合的有效措施，先后育成了低芥酸品种油研1号．双低品种油研2号和油研6号。较好的解决了优质与高产及抗病的矛盾，实现了双低与高产，双低与抗病和双低与高油酸及含油量较高的有机结合，为油菜品质育种提供了例证。
Through crossbreeding among varieties, the method of pedigree selection or pedigree selection was used to select the directional cultivation; the field selection and indoor selection were closely combined, and the shoots and buds always strengthened the yield traits and disease resistance selection; and the combination of oil content and low traits In the same position, beginning in the middle ages (selection criteria increase with age) to choose. To take breeding, identification, demonstration, breeding, promotion of organic combination of effective measures, has bred a low erucic acid oil research on the 1st. Low-grade varieties of oil Yan 2 and Youyan 6. It better solves the contradiction between high quality and high yield and disease resistance, and achieves organic combination of double low and high yield, double low and disease resistance and double low and high oleic acid and high oil content, which provides an example for rape quality breeding.
