在油菜杂种优势利用方面,国内外曾从选育自交不亲和系、化学杀雄、雄性不育两用系,三系等途径开展研究,並取得了较大的进展。我们从1975年开始进行甘蓝型油菜雄性不育“三系”的研究,于1983年选育成功甘蓝型油菜(B.napus)雄性不育系陕1A和陕2A,並实现了雄性不育系、保持系、恢复系三系配套。用雄性不育系陕2A和恢复系垦C_1选配的1代杂种“杂37”,经1982-1985年4年25个点次的试验,“杂37”在试
In rapeseed heterosis utilization, both at home and abroad have carried out researches on breeding self-incompatibility lines, chemical killing male-male lines, male sterile dual-purpose lines and tertiary lines, and made great progress. We started the research on the “three lines” of male sterility in Brassica napus from 1975, and successfully breeding B. napus male sterile lines Shaanxi 1A and Shaan 2A in 1983 and realizing the male sterile line , To maintain the Department of the Department of three systems recovery. The male sterile line Shaan 2A and restorer line C_1 were selected for the first generation hybrid “Hybrid 37”. After 25 years of test in 1982-1985 for 4 years, “Hybrid 37”
