稻瘟病、白葉枯病、褐飛虱和白背飛虱是危害水稻生產(chǎn)的主要病蟲害。實(shí)踐證明，培育抗病蟲品種是控制水稻病蟲害最經(jīng)濟(jì)和有效的途徑。總結(jié)了目前已報道和定位的抗病蟲基因的研究和利用情況，指出利用分子標(biāo)記輔助選擇聚合不同類型抗病蟲基因到同一品種，可以提高品種抗性、拓寬抗譜，是水稻抗病蟲品種培育的發(fā)展方向。
Blast (Magnaporthe grisea), bacterial blight (Xanthomonas oryzae pv. oryzae), brown planthopper (Nilaparvata lugens ) and white-backed planthopper (Sogatella furcifera) are major diseases and pests of rice. Utilization of rice varieties carrying resistance genes is one of the most economical, effective, and environment- friendly measures for the management of diseases and pests. The molecular markers, chromosome localization and the donor varieties of the identified disease/insect resistance genes of rice were summarized, and recent progress on molecular mapping of the resistance genes and on pyramiding different disease/insect resistance genes in rice by marker-assisted selection was reviewed. In addition, the strategy for developing better disease/insect resistant varieties was discussed.
