自1983年至1985年的三年间,先后对长江流域蚕豆的主要产地(四川、湖北、浙江、上海和江苏五个省市)的蚕豆病毒病进行了现场调查和采样测定。从各地共采集有病毒病症状的标样339份。根据它们在田间的症状、寄主范围、传毒介体、病毒粒体形态和大小以及血清学反应等测定结果,已经鉴定出蚕豆萎蔫病毒(BBWV)、芜菁花叶病毒(TuMV)、大豆花叶病毒(SMV)、蚕豆染色病毒(BBSV)菜豆黄花叶病毒(BYMV)和黄化卷叶病毒(BLRV?)等六种病毒。蚕豆萎蔫病毒的分布最广,危害也重。芜菁花叶病毒主要发生在江苏、浙江一带。黄化卷叶病毒则主要在湖北和江苏发生,危害大,损失重。蚕豆染色病毒都只是在国际蚕豆试验圃中发生,据调查,这些种子都是由国际旱地农业研究中心于1984年提供的。大豆花叶病毒的样本虽然不多,但作为一个越冬的桥梁寄主,其重要性不可忽视。 BBSV在中国是首次发生。TuMV和SMV能侵染蚕豆,这是第一次报道。
During the three years from 1983 to 1985, field surveys and sampling surveys were conducted on broad bean virus diseases in the main producing areas of the Yangtze River Valley (Sichuan, Hubei, Zhejiang, Shanghai and Jiangsu Provinces). A total of 339 samples of virus disease symptoms were collected from all over the country. Broad bean wilt virus (BBWV), turnip mosaic virus (TuMV), soybean flower have been identified based on their results in the field of symptoms, host range, transmission mediator, morphology and size of virion and serological response (SMV), BBSV, BYMV and BLRV (yellow leaf curl virus). Broad bean wilt virus is the most widely distributed, the harm is also heavy. Turnip mosaic virus occurs mainly in Jiangsu and Zhejiang areas. Erythrina virus occurs mainly in Hubei and Jiangsu, causing great damage and heavy losses. Vicia faba virus occurred only in the international broad bean test nursery, according to the survey, these seeds were provided by the International Center for Dryland Farming in 1984. Soybean mosaic virus samples, while small, but as a bridge over the winter host, its importance can not be ignored. BBSV is the first time in China. TuMV and SMV can infect Vicia faba, this is the first report.
