摘　　要：对浙粳22等晚粳稻品种干种子进行了60Co-γ射线400G的辐照处理,发芽率比较结果显示,不同晚粳稻品种间的辐照敏感性存在着一定程度的差异。浙粳22、浙粳27和秀水110对60Co-γ射线较敏感,而浙粳30、嘉991和秀水63对60Co-γ射线的敏感性相对较弱。8 japonica rice dry seeds were treated by 400 gray 60Co-γ ray,such as zhejing 22.to study the radiation sensitivity to 60Co-γ ray of different japonica rice varieties.The results showed that there were some differences of the sensitivity among japonica varieties.Zhejing22,Zhejing27 and Xiushui 110 were more susceptible,while Zhejing30,Jia991 and Xiushui63 were more resistant to 60Co-γ ray radiation.
