小麦黄矮病是中国小麦产区的重要病害之一.为得到抗小麦黄矮病种质资源及品种,2007-2008年,采用诱发行早播的方法鉴定了383份小麦种质资源,并对252种小麦品种使用堆测法进行人工接种鉴定,得到182种抗病种质资源和17种抗病品种.经重复鉴定,从中筛选出抗病种质资源23份,抗病品种15种.小麦感染BYDV后,临203、晋麦47具有一定的恢复现象,并结合受害品种的产量损失来确定其耐病特性.%Wheat yellow dwarf disease is a major disease in China. In order to prevent yellow dwarf disease from occurring and epidemic, early sowing and hill plot technique were used to identify germ-plasm resources of wheat and wheat varieties in this research. 252 cultivars sowed by hill plot technique and 383 samples of different wheat germplasm materials were evaluated for resistance to BYDV by artificial inoculation and natural infection in the field during 2007-2008, respectively. The resistant cultivars and germplasm materials achieved last year were identified again in 2008; the results showed that there were 15 major cultivars and 23 samples of germplasm materials. And some infected BYDV could recover in some different extent; resistant identification was combining with yield loss caused by BYDV.
