由国际水稻研究所首先发现的一种由褐稻虱传播的新的水稻病毒病,1977年4月6日在菲律宾正式命名为水稻裂叶矮缩病。 在我国,于1978年10月由福建农学院植保系植物病毒研究室主任谢联辉等人在福建省沙县洋坊的水稻四优2号品种上首次发现此病,并重新命名为水稻锯齿叶矮缩病(载《科学通报》1980年第13期)。据报导,此病多属零星发生,但个别田植株发病率有达10％以上的。有些当家品种,特别是一些杂优组合,极易感病,是当前水稻生产上的一个新的潜在威胁。 继后,广东省农科院植保所周亮高同志等,在该省从化县吕田公社莲麻大队亦发现三个杂交后代感染此病。
A new rice virus disease first reported by the International Rice Research Institute to be transmitted by the brown planthopper was formally named rice leaf splint dwarf disease in the Philippines on April 6, In China, the disease was first discovered in October 1978 by XIE Lian-hui, director of plant virus research department of Phytosanitary Department of Fujian Agricultural College, and the first rice variety Siyou 2 in Yangfang, Shaxian County, Fujian Province, Disease (contained in Science Bulletin, No. 13, 1980). It is reported that the disease is mostly sporadic, but the incidence of individual field plants have reached more than 10%. Some headed varieties, especially some combinations of heterosis, are highly susceptible to diseases and are a new potential threat to current rice production. After that, Comrade Zhou Lianggao of Plant Protection Institute of Guangdong Academy of Agricultural Sciences, etc., also found three hybrid offspring infected with the disease in the Lianma unit of Lvtian commune in Conghua County in the province.
