病毒鉴定采集的具有不同病毒病症状的甘薯品种大多与甘薯羽状斑驳病毒(SPFMV)抗血清发生反应,这说明血清学变异小。从中分离到14个SPFMV变异株,让其系统侵染牵牛花(Ipomoea nil)和巴西牵牛(I.setosa)。其中8株容易在苋色藜(Chenopodium amaranticolor)和昆诺藜(C.quinoa)上产生大量的局
Most of the sweetpotato cultivars with different viral disease symptoms detected by virus reaction reacted with anther of sweetpotato feather mottle virus (SPFMV), which indicated that the serological variation was small. Fourteen SPFMV variants were isolated and systematically infected with Ipomoea nil and I.setosa. Of these, 8 easily produced a large number of bouts on Chenopodium amaranticolor and C. quinoa
