| 摘 要： | 以云南灰飞虱(Laodelphaxstriatellus)为介体昆虫,以4个水稻品种为寄主,通过人工接种对采自云南、江苏、河南、山东、安徽等省的水稻条纹病毒(Rice stripe virus,RSV)23个分离物进行传毒试验.致病性评价结果表明,23个分离物可划分为5个等级,即强致病型、次强致病型、中致病型、弱致病型、极弱致病型.致病性分化表现在地理差异、毒株差异及水稻品种差异三方面.不同分离物在寄主发病率、发病时间、症状表现以及对灰飞虱传毒效率等方面都存在差异.

| Abstract: | Twenty-three isolates of Rice stripe virus(RSV) from Yunnan,Jiangsu,Shandong,Henan,Anhui were inoculated to four rice varieties by landelphax striatellus.According to the evaluations of pathogenicity,the isolates could be divided into five grades,namely strong virus(sv),semi-strong virus(ss),middle strong virus(ms),weak virus(wv) and least weak virus(lw).Pathogenicity differentiation was shown to correlate with geographic distribution,strain differences and rice varieties.There were differences among isolat... |
