综述了我国植物诱变育种技术在提高诱变效率和诱变与组培相结合两方面的研究情况。诱变效率的研究,包括诱变时期和诱变材料的选择,新诱变源的开拓,复合处理,DNA损伤与修复;在诱变与组培相结合方面,包括外植体和细胞辐射敏感性研究,增加体细胞无性系变异和体外选择。对一些新的研究领域作了探讨,包括γ融合,遗传转移,农艺性状有利基因分离。 The research situation of plant mutagenesis breeding in China on improving the mutagenic efficiency and combination of mutagenesis and tissue culture are summarized. Mutagenesis efficiency studies include mutagenesis and selection of mutagenic materials, development of new mutagenesis sources, complex treatment, DNA damage and repair, and combination of mutagenesis and tissue culture, including explant and cell-radiation-sensitive Sex studies to increase somaclonal variations and in vitro selection. A number of new research areas were explored, including gamma fusion, genetic transfer, and agronomic trait profiling.
