江苏省淮阴地区所从1975年起开展油菜低芥酸新品种选育工作,经过杂交育种,从大量杂种后代选育出“233—1”和“264”两个芥酸含量稳定在4.5%以内的甘兰型油菜新品系。“238—1”是用当地芥菜作母本,Oro 作父本杂交选育而成的。该品系芥酸含量为4.3%,油酸为53.1%,亚油酸为24.8%。株高中等,一次有效分枝较多,单株结角约350—400个,每角21粒种子,千粒重3.4—3.7克,在中等肥力下试种亩产
The Huaiyin area of Jiangsu Province started to carry out selection and breeding of new varieties of low-erucic acid of rapeseed starting in 1975. After crossing breeding, the erucic acid content of “233-1” and “264” was bred from many offspring of hybrids within 4.5% Of the new type of Brassica napus. “238-1” was bred from the mother mustard of the local mustard and Oro as a male parent. This product has an erucic acid content of 4.3%, oleic acid of 53.1% and linoleic acid of 24.8%. Plant height medium, more effective branches more, single plant knot about 350-400, 21 seeds per corner, thousand grain weight 3.4-3.7 grams, try medium yield
