摘　　要：小麦黄花叶病是一种全球性的土传病毒病,严重时会导致小麦产量大幅下降。小麦黄花叶病毒(WYMV)是主要的病原体之一,属于马铃薯Y病毒科(Potyviridae)大麦黄花叶病毒属(Bymovirus),以禾谷多黏菌(Polymyxa graminis)为媒介感染小麦。目前已鉴定出14个抗WYMV的基因位点,图位克隆了1个抗病基因,证实了3个基因具有抗病性调控功能,已育成多个抗病小麦品种(系)。本文从小麦黄花叶病毒的病原体特性、病害分布、小麦抗性遗传和抗病育种等方面,综述了WYMV及小麦抗病性的研究进展,并对WYMV抗性基因挖掘和小麦抗病育种应用进行了展望。Wheat yellow mosaic disease is a worldwide soil borne virus disease that can lead to a severe reduction in wheat yield.The main pathogen wheat yellow mosaic virus(WYMV)belongs to genus Bymovirus of family Potyviridae,and it is transmitted by Polymyxa graminis.At present,14 loci conferring resistance to WYMV have been identified,a resistance gene has been cloned by map-based cloning,3 resistance genes have been confirmed to confer resistance,and a number of resistant varieties have been developed.This paper presented a comprehensive overview of recent advancements in the understanding of pathogen characteristics,disease distribution and resistance breeding of wheat.Finally,we discussed the prospects of researches on WYMV resistant genes and the potential applications in wheat breeding.
