离体培养条件下的突变体诱变和筛选研究工作近十几年来已取得很大进展。在双子叶植物方面,美国已选育出抗非选择性 Roundup 除草剂的棉花新品种。我国也将抗除草剂阿特拉津的大豆植株培育成功。在单子叶植物方面,我国的陈少林、田文忠等利用水稻花粉愈伤组织已筛选出抗盐突变体。肖海林、赵世绪利用小麦幼 Much progress has been made in the research on mutagenesis and screening of mutants in vitro in recent ten years. In dicots, the United States has bred new varieties of cotton that are resistant to non-selective Roundup herbicides. China will also be resistant to herbicide atrazine plant cultivation success. In monocots, China’s Chen Shaolin, Tian Wenzhong and other pollen callus using rice have been screened salt-resistant mutants. Xiao Hailin, Zhao Shixu use of wheat young
