摘要： 利用强迫饲毒、集团接种、非嗜性测验、抗生性测验的方法研究与分析了8个抗条纹叶枯病水稻品种对条纹病毒和介体灰飞虱的抗性,发现不同水稻抗性品种的抗性特征并不完全相同。IR36、Kasalath、窄叶青8号、道人桥、DV85既抗条纹病毒又抗介体灰飞虱，对条纹叶枯病所表现的抗性是条纹病毒和介体灰飞虱抗性共同作用的结果； 爱知97和Kenta Nakan抗条纹病毒，但不抗介体灰飞虱，对条纹叶枯病所表现的抗性是品种对条纹病毒的抗性；而IR24对条纹病毒和介体灰飞虱仅表现中等抗性。

Abstract: The resistance to rice stripe virus (RSV) and vector, small brown planthopper (SBPH) (Laodelphax striatellus Fallen) was studied and analyzed in eight indica rice varieties by using individual inoculation, mass inoculation, non-preference test and antibiosis test. The mechanism of resistance to RSV and vector SBPH was different in the eight rice varieties. Some rice varieties were highly resistant to RSV and vector SBPH, such as IR36, Kasalath, Zhaiyeqing 8, Daorenqiao and DV85; some others, such as Aichi 97 and Kenta Nakan were only resistant to RSV but susceptible to SBPH; and IR24 was moderately resistant to RSV and SBPH.
