摘　　要：黄矮病是小麦的一种主要病毒病,感染小麦后发展迅猛,造成小麦严重减产,成为一个世界性难题。本文论证了全球小麦抗黄矮病育种的重要性;阐明了目前已将外源抗黄矮病基因导入小麦,逐步培育出一系列抗病种质材料,为抗黄矮病育种奠定了良好基础;明确了几个重要的黄矮病抗源以及不同抗性基因具有一定的遗传差异;指出抗黄矮病育种的成就并提出未来的研究方向。As an important virus disease of Barley Yellow Dwarf Virus（BYDV） ,wheat yellow dwarf disease has become a global problem due to overwhelming infections and severe reductions in yield. This paper discusses the importance of BYDV resistance from scientific viewpoint. It introduces progresses regarding BYDV-resistance gene from close relatives of wheat into common wheat and elaborated on the development of a series of resistant germplasms,which can establish a solid foundation for resistance breeding. The article elucidates differences in genetic background of some important resources and resistant genes. Moreover, some achievements in BYDV-resistant variety breeding are discussed and future research directions are advanced.
