摘要
根据介体蚜虫传毒力和植株病毒含量抗性指标，小偃麦中５和中４高抗小麦黄矮病（ＢＹＤＶ）及其该病毒主要株系ＧＰＶ和ＤＡＶ。抗病性持久、稳定。
According to the indexes of ability of transmission of vector aphids and content of virus in plants,the results showed that the wheat cultivars Xiaoyan, Zhong 5 and Zhong 4 were resistant to BYDVand its main strains GPV and DAV.
