近年来,国外在抗性突变体离体筛选方面取得显著进展,先后获得烟草、马铃茹、甘蔗、水稻、小麦、大麦、番茄、玉米、油菜、大豆、胡萝卜和苜蓿等作物抗性突变体;并育成了抗斐济病毒病、霜霉病和眼斑病的甘蔗品种,抗叶枯病的小麦品种以及抗除草剂黄草灵的大麦新品种。七十年代,日本学者石井和小笠原等人试图利用植物组织培养技术进行抗稻瘟病突变体离体筛选,但因污染问题未能成功。最近,我国上海市农科院郑祖玲等人指
In recent years, significant progress has been made in screening in vitro screening of resistant mutants, and crop resistant mutants such as tobacco, rahuan ru, sugarcane, rice, wheat, barley, tomato, corn, rape, soybean, carrot and alfalfa have been obtained successively; Bred into resistant varieties of Fijian virus, downy mildew and eye spot disease, wheat varieties resistant to leaf blight, and new barley varieties resistant to herbicide Huangcao Ling. In the seventies, Japanese scholars Ishii and Ogasawara tried to use in vitro tissue culture techniques to screen blast resistant mutants in vitro, but the pollution problem was not successful. Recently, China’s Shanghai Academy of Agricultural Sciences Zheng Zuling and others refer to
