【摘要】 通过人工杂交将澳大利亚引进的低芥酸品系Ｚｅｍ－１的低芥酸基因导入芥菜型三系和云南地方优良品种，分别获得芥酸含量低、不育性状稳定的细胞质雄性不育系江矮Ａ和恢复系８８—１２２。江矮Ａ与８８—１２２组配的杂交组合江矮Ｄ１优势强，株型较矮而紧凑，耐旱、耐瘠，适应性较广，高产稳产，油酸含量３５．４１％，亚油酸３３．０６％，芥酸２．３９％，含油量４３．４８％，恢复株率９５％以上。１９９５～１９９６年全省旱地区试平均单产２０９０．１ｋｇ／ｈｍ２，较昆明高棵增产７６．２％，较芥油一号增产７．９％。更多还原

【Abstract】 A low erucic stable sterility CMS line Jiang Ai A and a restorer 88—122 were obtained respectively by transfered the low erucic gene from an Australian line Zem 1 into the 3 lines and Yunnan’s desirable cultivars by artificial cross. The hybrid, Jiang Ai D 1 (Jiang Ai A×88—122) was vigorous in heterosis, comparatively short and compact in plant form, tolerant to drought and barrenness, widely adaptable, stable and high in yield, 35.41% of oleic, 33.06% of linoleic and 2.39% of erucic acid in it’s oil, 43.48% of oil content in it’s seeds. The restoring rate was up to 95%. In the provincial reginal dryland tests in 1995～1996, Jiang Ai D 1 gave an average yield up to 2 090.1 kg/hm 2, This was higher than Kunming Gaoke by 76.2%, and Jieyou No.1 7.9%.更多还原
