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。
Nilaparvata lugens Stal, Sogatella furcifera Horvath and Laodelphax striatellusFaléln are important pests in rice production and cause serious economic losses to rice production in China. Cultivation and utilization of insect-resistant varieties is a cost-effective measure against planthoppers. Resistance genetic and resistance gene research is the basis for insect resistance breeding. At present, great progress has been made in the research on the genetics and localization of the brown planthopper resistance genes in rice, including 21 major genes, more than 50 QTLs and many BPH resistance-related genes being excavated, located and cloned, while the whitebacked planthopper and the gray fly Lice resistance genes have yet to be further identified and identified. In addition, the application of planthopper resistance genes in the future should be strengthened.
