根据分离物的蚜虫传播能力及其在不同蚕豆品种上的反应,划分为芜菁花叶病毒的两个株系,分别命名为蚜传株系(TuMV-AT)和非蚜传株系(TuMV-NAT)。蚜传株系以非持久性方式传播,只侵染部份供试蚕豆品种,产生红褐色坏死斑。非蚜传株系侵染全部供试蚕豆品种,在部份供试蚕豆品种上,产生红褐色坏死斑和系统性白色斑驳症状。苋色藜及蚕豆品种“成胡10号”和“优系50”可作为株系鉴别寄主。
According to the aphid transmission ability of isolates and their responses to different broad bean varieties, the two strains of turnip mosaic virus were named as TuMV-AT and TuMV -NAT). Aphid-transmitted strains spread in a non-persistent manner, infecting only part of the tested varieties of beans, producing red-brown necrotic spots. The non-aphid-resistant strains infect all the tested varieties of broad bean, and on some of the tested varieties of broad bean, they produced red-brown necrotic spots and systemic white mottled symptoms. Amaranthus curd and broad bean varieties “into Hu 10” and “excellent line 50” can be used as host identification host.
