摘　　要：褐飞虱(Nilaparvata lugensStal)、白背飞虱(Sogatella furciferaHorvath)和灰飞虱(Laodelphax striatellusFaléln)是水稻生产上的重要害虫,给我国水稻生产造成了严重的经济损失。培育和利用抗虫品种是防治稻飞虱经济有效的措施。抗性遗传和抗性基因研究是进行抗虫育种的基础。目前,有关水稻抗褐飞虱基因的遗传与定位研究取得了较大进展,包括21个主基因、50余个QTLs和许多褐飞虱抗性相关基因被发掘、定位与克隆,而白背飞虱和灰飞虱抗性基因尚有待进一步发掘和鉴定。此外,今后应加强稻飞虱抗性基因在生产上的应用。Brown planthopper（ BPH, Nilaparvata lugens Stal）, whitebacked planthopper（ WBPH, Sogatella furcifera Horvath）and small brown planthopper（ SBPH,Laodelphax striatellus Fallen）are three serious pests of rice, which often cause major yield losses and quality reduction in China. Breeding and utilization of resistant varieties are economical and effective in controlling plant hoppers. Study on resistance inheritance and gene is the base of breed- ing for pest resistance. Nowadays, great progress in rice genes for resistance to brown planthopper has been made and 21 major BPH resistance genes, more than 50 QTLs, and some resistance-related genes were identified, mapped ,and cloned. However, research on WBPH and SBPH resistance genes is still in the early stage. In addi- tion, the application of resistance genes to rice production has to be promoted.
