摘　　要：稻瘟病、白叶枯病、褐飞虱和白背飞虱是危害水稻生产的主要病虫害。实践证明,培育抗病虫品种是控制水稻病虫害最经济和有效的途径。总结了目前已报道和定位的抗病虫基因的研究和利用情况,指出利用分子标记辅助选择聚合不同类型抗病虫基因到同一品种,可以提高品种抗性、拓宽抗谱,是水稻抗病虫品种培育的发展方向。Blast（Magnaporthe grisea）,bacterial blight（Xanthomonas oryzae pv.oryzae）,brown planthopper（Nilaparvata lugens） and white-backed planthopper（Sogatella furcifera） are major diseases and pests of rice.Utilization of rice varieties carrying resistance genes is one of the most economical,effective,and environment-friendly measures for the management of diseases and pests.The molecular markers,chromosome localization and the donor varieties of the identified disease/insect resistance genes of rice were summarized,and recent progress on molecular mapping of the resistance genes and on pyramiding different disease/insect resistance genes in rice by marker-assisted selection was reviewed.In addition,the strategy for developing better disease/insect resistant varieties was discussed.
