摘　　要：浙江省是我国长江中下游主要的粮食生产区,长期以来水稻生产受稻瘟病的严重影响。在过去的10年,浙江省在稻瘟病防控技术上面取得了很大进展。本研究回顾了浙江省稻瘟病菌优势种群的变化和优势小种的更新情况,总结了近10年已育成的203个品种的稻瘟病抗性变化趋势,归纳了稻瘟病抗病基因的克隆和功能研究,以及这些抗病基因结合分子标记辅助育种技术在水稻抗病育种中的应用情况。本文还展望了田间水肥的管理模式、抗稻瘟病基因聚合水稻品种选育和无毒基因在稻瘟病流行预测上的应用。Zhejiang Province is a major grain production area in the middle and lower reaches of the Yangtze River,where rice production has been seriously affected by rice blast for a long time.In the past ten years,Zhejiang Province has made great progress in rice blast prevention and control technology.This study reviewed the changes of the dominant populations of rice blast fungus and the update of dominant races in Zhejiang Province,summarized the changing trends of rice blast resistance of 203 rice varieties that had been bred in the past ten years,the clones of rice blast resistance genes,and the application of these disease resistance genes in rice disease resistance breeding.The management mode of water and fertilizer in the field,the breeding of multiple application of rice blast resistance gene aggregation rice varieties and avirulence genes in production of rice blast epidemic prediction is prospected in this paper.
