摘 要 ：褐飞虱是为害水稻生产的重要害虫,利用寄主抗性培育抗褐飞虱品种被认为是防治其为害的有效途径。自20世纪70年代起,各国相继开展了水稻褐飞虱抗性基因的发掘工作,截至2007年12月,经国际注册确认和报道的水稻抗褐飞虱基因共22个,其中12个为显性基因(Bph),10个为隐性基因(bph),已被定位的达18个,此外还鉴定了一些重要的抗性QTLs。文中还讨论了综合防治褐飞虱策略等合理利用抗性基因的问题。

Abstract:The brown planthopper (BPH) is one of the most serious insect pests in rice production. The breeding of varieties resistant to BPH by applying host-plant resistance has been recognized as an economic and effective measure for BPH control. Systematic genetic studies on rice resistance to BPH have been conducted in world since 1971. Up to December 2007, there are a total of 22 BPH resistance genes registered internationally or reported. Among them, 12 and 10 out of the genes are dominant and recessive, respectively, and 18 of them have been located. Besides, some important resistant QTLs have been detected. Application of resistance to BPH was also discussed.
