摘　　要：为明确江苏省主栽抗病粳稻品种对条纹叶枯病的抗性特征,采用苗期接种鉴定、非嗜性测验和抗生性测验的方法,分析了8个主栽抗病品种对水稻条纹病毒和介体灰飞虱的抗性。结果发现:品种的抗病性和抗虫性表现并不一致。抗病性分析发现,供试品种均抗条纹病毒;抗虫性分析发现,镇稻88等4个品种表现为较弱的抗虫性,其余品种均表现为无抗虫性。表明:供试抗病品种对水稻条纹叶枯病表现的抗性主要来源于对条纹病毒的抗性。The methods of inoculation at seedling stage,non-preference test and antibiosis test were taken to analyze the resistance to rice stripe virus （RSV） and the vector,small brown planthopper （SBPH） （Laodelphax striatellus Fallèn） for the purpose of identifying the resistance mechanism of the major commercial japonica rice.The results turned out that the resistance to RSV and vector SBPH was not consistent among the eight rice varieties.The analyses of resistance of rice varieties to RSV indicated that all the rice species selected in this study were resistant to RSV.However,the resistance to SBPH suggested that the rice varieties of Zhendao 88,Zhendao 99,Lianjing 4 and Yandao 8 were weakly resistant to SBPH,while the others were inclined to be infected by SBPH.Therefore,the rice stripe disease resistance of the varieties were mainly derived from the resistance to the virus.
