据《国际水稻研究通讯》1983年3月报道,国际水稻研究所研究员P.Q.Cabauatan和H.Hibino在该所的内湖和Koronadal试验场同时发现一种水稻新病害。经系统鉴定研究后,鉴于该病病原菌与日本和菲律宾的草丛矮缩病毒血清学分析的相关性,他们判断该病原菌为草丛矮缩病病毒的新菌系,从而命名为草丛矮缩病毒菌系2,原草丛矮缩病毒则编号为菌系1。目前已确证,草丛矮缩病毒菌系2不能通过水稻病株的汁液、种子和根区土壤传播,此外,绿叶蝉也不具有传播2系菌的能力。该菌系的传播媒介是褐稻虱,在虫体上的潜伏期5—21天,以6—8天为多。5—30％的褐稻虱能传毒。
According to the International Rice Research Newsletter, reported in March 1983, P.Q. Cabuatan and H. Hibino, researchers at the International Rice Research Institute, discovered a new rice disease simultaneously at the institute’s Inner Lake and Koronadal test sites. After systematic identification and research, given the relevance of the pathogen to the serological analysis of grass dwarf virus in Japan and the Philippines, they judged the pathogen to be a new strain of grass dwarf virus and named it as a grass dwarf virus strain 2, the original grass dwarf virus numbering strain 1. It has been confirmed that the grass dwarf virus strain 2 can not be transmitted through the sap, seed and root zone soil of rice diseased plants. In addition, the green leafhopper does not have the ability to propagate 2-line bacteria. The strain of the media is brown rice louse, in the larvae of the incubation period of 5-21 days to 6-8 days more. 5-30% of brown planthopper can poison.
