Abstract

Brown planthopper(BPH,Nilaparvata lugens)and whitebacked planthopper(WBPH,Sogatella furcifera)are two major pests of rice. The application of resistant cultivars have proven to be an effective way to control these two pests. To day,a great progress has been made in the field of exploitation and utilization of resistant resource to BPH and WBPH,and a number of resistance genes were identified or mapped in rice,which derived from cultival and wild relatives. The present paper reviews the recent advances in resistance genes mapping and QTL analysis to BPH and WBPH,and summarizes the utilization in rice breeding program by marker-assisted selection. The problems and prospects of gene mapping and its application are also discussed in this paper.
