| 摘 要： | 褐飞虱(BPH,Nilaparvata lugens)与白背飞虱(WBPH,Sogatellafurcifera)是水稻的两种重要害虫,培育抗虫品种是防治这两种飞虱的有效途经.近年水稻抗褐飞虱与白背飞虱资源发掘与利用研究取得长足进展,迄今已经在水稻上鉴定或定位了许多抗稻飞虱基因,这些基因来源于水稻的栽培种和野生种.本文就近年来水稻抗褐飞虱与白背飞虱主基因定位和QTL分析研究进展进行阐述.并简要回顾分子标记辅助选择在抗飞虱育种上的应用概况,对当前基因定位研究中存在的问题及其应用前景作了探讨.

| Abstract: | Brown planthopper (BPH,Nihrparvata lugens)and whitebacked planthopper (WBPH ,Sogatella furcifera)are two major pests of rice. The application of resistant cuhivars 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 cuhival 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. |
