近年来我们以提高辐射诱变效率和选择效率为中心,以水稻为主要研究对象,对作物的辐射敏感性,辐照亲本的选择,理化因素复合处理,新诱变因素的开拓利用等方面进行了较为系统的研究。结果表明,选用辐射敏感型亲本材料辐照,辐照杂合材料,适宜剂量的理化因素复合处理组合,新诱变因素的应用均能有效地提高辐射诱变效率。 In recent years, we have focused on improving the efficiency of radiation mutagenesis and selection efficiency, taking rice as the main research object, and conducted the research on the radiation sensitivity of crops, the selection of irradiated parents, the combination of physical and chemical factors, and the utilization of new mutagenic factors A more systematic study. The results showed that the radiation mutagenesis efficiency could be effectively improved by using radiation-sensitive parent material irradiation, irradiation hybrid materials and the combination of physico-chemical factors at appropriate dosage.
