摘　　要： 空间诱变育种抗病性研究正越来越受到重视,我国利用空间诱变育种技术,已选育出一些抗稻瘟病新品种和新抗源.文章对水稻空间诱变稻瘟病抗性变异特点及空间诱变抗稻瘟病育种成果,以及空间诱变稻瘟病抗性变异机理的研究进展进行了综述,并对水稻空间诱变育种抗稻瘟病的研究前景进行了展望. The research on the resistance improvement by space mutation is drawing more and more attention.Some new varieties and resources resistant to blast have been selected since rice breeding by space mutation was conducted in China. The characteristics and research progress in mechanism of resistance variation of rice lines to blast by space mutation were reviewed. Additionally, the prospect of research on resistance to blast by rice space mutation breeding was discussed.
