选用西昌反修麦为材料，经６０Ｃｏγ射线辐照之后，播种前用赤霉素（Ｇｉｂｂｅｒｅｌｉｎ）浸种复合处理。诱变育成矮秆抗倒，株型紧凑，幼苗直立，叶片短宽，适应性较广，耐瘠，耐湿，抗条锈病小麦新品种西辐九号，一般产量６８４０ｋｇ／ｈｍ２。研究表明，γ辐照与赤霉素复合处理能减轻辐射损伤，有效的提高辐照当代的田间出苗率，拓宽突变谱，扩大变异群体，提高有益突变频率。赤霉素可作辐射防护剂 Xichang anti-malt selection for the material, after 60Coγ-ray irradiation, before planting gibberellin (Gibberelin) Soaking compound treatment. Mutation breeding dwarf lodging resistance, compact plant type, seedlings upright, leaves wide and wide, wide adaptability, barren, moisture resistance, stripe rust resistant new varieties of wheat Xifu 9, the general output 6840kg / hm2. The results showed that the combination of γ irradiation and gibberellin could reduce the radiation damage and effectively increase the germination rate, broaden the mutation spectrum, expand the mutation population and increase the frequency of beneficial mutation in field. Gibberellin can be used as a radioprotectant
