分子标记辅助选择在水稻抗稻瘟病育种中的研究进展

Research Progress of Molecular Marker-assisted Selection in Rice Blast Resistance Varieties Breeding

稻瘟病作为一种世界性稻作病害,严重制约了水稻的产量和品质。培育抗病品种是最为经济有效的降低稻瘟病危害的方法。综述了近年来稻瘟病抗性资源鉴选、抗病基因定位和克隆及创新利用等方面的工作。同时,还对分子标记辅助选择在抗稻瘟病品种选育中的应用进行了展望。

Rice blast,as a worldwide fungal disease of rice, severely decreases the yield and quality of rice. The most economical and effective method to resist rice blast is researching resistance varieties. Ted identification of disease resistant germplasm resources,gene mapping,gene cloning,innovation and utilization of them were reviewed. Furthermore, it also prospected utilization of molecular markerssisted selection in rice blast resistance varieties breeding.
