【摘要】 <正>赤霉病或称为镰刀菌穗腐病,是一种世界性病害,由镰刀菌(Fusarium)引起,在中国和美国的主要致病菌为禾谷镰刀菌(Fusarium graminearum Schwabe),是影响小麦高产、稳产和品质的重要因素之一。小麦赤霉病的频繁流行过去主要发生于东亚和南美在小麦生长的开花期具有温暖潮湿气候的地区,但在20世纪80年代后期以来,由于全球气候变化和耕作制度的影响使北美和欧洲也频繁发生,据报道,美国和加拿大自1993～1997年赤霉病的更多还原

【Abstract】 Wheat Fusarium head blight (FHB) is one of the most serious wheatdiseases worldwide. Conventional wheat breeding for FHB resistance has been hindered bycomprehensive genetic inheritance and environment affection. Molecular marker--assistedselection (MAS) facilitates plant breeding and accelerates the breeding process. Thisreview focuses on the latest advance in identification of QTL resistant to FHB, as well asthe problems concerning MAS practice. It is already known that there is one major QTLon chromosome 3B in Sumai3and its derivatives such as Ning7840, the widely applied FHBresistance source. QTL analyses of other FHB resistance sources including Frontana,Wangshuibai and Ning894037 are not deeply concerned as those of Sumai3 and nosatisfying major QTLs have been obtained. To increase the efficiency of MAS, specialpopulation should be constructed to find QTL and molecular markers tightly linked toresistance gene should be identified. Developing simple and high throughput markerdetection technique with lower cost is also one of the most important preconditions forMAS application in conventional breeding program.更多还原
