摘　　要：褐飞虱严重影响水稻的产量和品质,抗虫品种的培育和种植是控制该虫害最安全有效的措施。水稻抗褐飞虱育种的关键是抗虫基因的发掘和合理利用。目前至少报道了34个褐飞虱抗性位点,其中28个主效抗性基因已被定位,显性基因Bph3、Bph14和Bph26已被成功克隆。介绍了水稻褐飞虱的生物型及抗性机理、褐飞虱抗性基因定位与克隆及抗虫基因在育种上的应用,并对水稻褐飞虱抗性育种面临的问题和应用前景进行了讨论。Brown planthopper is one of the most devastating diseases and seriously decreases the yield and quality in rice. Development and adoption of pest-resistant varieties is the most economic and effective measure to control rice brown planthopper. Therefore,the discovery and utilization of rice brown planthopper resistance genes plays a key role in rice breeding. Up to now,there have been at least 34 rice brown planthopper resistance loci reported,28 major resistance genes mapped and three（ Bph3,Bph14 and Bph26） cloned. In this paper,the authors made a brief review on the biotypes of brown planthopper,resistance mechanism,gene mapping and cloning as well as the application of resistance genes in breeding,and discussed the problems and application prospect of rice brown planthopper resistance breeding.
