摘要
[目的]鉴定水稻地方品种资源条纹叶枯病的抗性。[方法]利用田间自然诱发鉴定对国内外的119份地方水稻品种资源材料进行了水稻条纹叶枯病的抗性鉴定。[结果]在119份供试材料中,56份籼稻材料中55份抗水稻条纹叶枯病;63份粳稻材料中,2份粳稻抗条纹叶枯病,其余61份都不抗水稻条纹叶枯病。[结论]该研究表明我国的地方品种资源蕴藏着丰富的抗水稻条纹叶枯病资源,这些抗病资源的开发利用将有助于解决我国和东南亚国家长期单一使用Stv-bi基因的现状。
[Objective] The aim of this study was to screen rice strip virus （RSV）-resistant landraces. [Method] The resistance of 119 rice landraces to rice stripe virus was identified in field spontaneously infected with smal plant-hopper. [Result] There were 55 landraces resistant to rice strip disease in 56 indica rice landraces, but on-ly two resistant to rice strip disease in 63 japonica rice landraces. [Conclusion] The results revealed that there were abundant rice landscapes resistant to RSV in Chi-na, and these varieties can be used to develop more genes resistant to RSV.
