芝麻是我国主要的油料作物,引起芝麻黄化花叶等症状的芝麻花叶病病原是马铃薯Y病毒属花生条纹病毒芝麻分离物(peanut stripe virus sesame isolate,PSt V-se)(杨书军等,1993;晏立英等,2009),且国外也研究发现芝麻花叶病病原是马铃薯Y病毒属的成员之一(Sreenivasulu et al.,1994;Pappu et al.,1997)。河南省作为芝麻主产区之一,引起当地芝麻花叶病的病原尚不清楚,本试验通过采集河南

Sesame is a major oilseed crop in our country. The pathogen of sesame mosaic disease caused by yellowing of sesame yellow mosaic is the peanut stripe virus sesame isolate (PSt V-se) (Yang Shujun et al., 1993; Yan Liying Et al., 2009), and foreign studies have also found that the pathogens of sesame mosaic disease are members of the genus Potato virus Y (Sreenivasulu et al., 1994; Pappu et al., 1997). Henan Province as one of the main producing areas of sesame seeds, causing the local pathogens of sesame mosaic is not yet clear, the test by collecting Henan
