根据八个大豆鉴别品种对87个大豆花叶病毒毒株的反应划分成三个类型。只侵染感病品种(Rampage、里外青、黑农28),不侵染中抗和高抗品种的毒株属于类型1;完全侵染感病品种,并侵染中抗品种之一(Marshall、丹×太、东农16)。不侵染高抗品种的属于类型2;对感病品种及中抗品种都能侵染,并能侵染高抗品种之一(Kwanggyo及雷电),属于类型3。类型2型有可能是分布较广的株系;类型3是毒力较强的株系,应给予重视。 供试毒株经鉴别寄主症状、寄主范围、汁液稳定性、传毒介体。菜豆Top Crop检索、血清检测、病毒提纯、电镜观察病毒粒体形态等测定确认是SMV。
The response to 87 soybean mosaic virus strains was divided into three types based on the identification of eight soybean cultivars. Only the susceptible varieties (Rampage, Liqingqing, Heinong28), non-invasive and resistant varieties of middle and high resistant strains belong to type 1; fully infected susceptible varieties and infected one of the resistant varieties ( Marshall, Dan × too, Dongnon 16). Non-invasive high-resistant varieties are of type 2; susceptible and resistant varieties are susceptible to infection and can infect one of the highly resistant varieties (Kwanggyo and Thunderbolts), which is type 3. Type 2 may be more widely distributed strains; Type 3 is a virulent strain, should be given attention. The tested strains were identified host symptoms, host range, juice stability, toxic mediators. Beans Topcatch search, serum detection, virus purification, electron microscopy virus morphology and other measurements confirmed SMV.
