水稻诱变育种实践证明:诱变处理较易获得矮秆突变体,可供生产直接应用或作中间材料间接利用。国内外学者为充分利用矮秆突变资源,曾做过遗传动态基础研究,但对矮秆突变体细胞学基础研究较少。为明确水稻矮秆突变的细胞学基础,丰富诱变育 Mutagenesis breeding in rice has proved that it is easier to obtain dwarf mutants by mutagenesis and can be used for direct production or indirect utilization of intermediate materials. Domestic and foreign scholars have made basic research on genetic dynamics to make full use of dwarf mutant resources, but few studies on the basis of dwarf mutant cytology. In order to clarify the cytological basis of rice dwarf mutation, enrich mutagenesis
