摘　　要：对 6 5份从 IRRI引进的野生稻渗入基因系进行稻瘟病、白叶枯病及褐飞虱抗性鉴定 ,筛选出 34份抗稻瘟病品系 ,15份高抗白叶枯病品系 ,35份中抗白叶枯病品系 ,2 1份抗褐飞虱品系 ,44份中抗褐飞虱品系 ,30份兼抗 2种病虫害的品系和 2 7份兼抗 3种病虫害的品系 。Resistance identification of 65 introgression lines derived from wild species of Oryza of IRRI was carried out to examine their resistivity to Rice Blast,Bacterial Blight and Brown Planthopper. Among the 65 lines,34 lines were screened which resisted Rice Blast ;15 lines resisted highly and 35 lines resisted fairly to Bacterial Blight ; 3 lines had a high and 44 lines had a middle resistivity to Brown Planthopper, and 18 lines showed facultative resistance to two pests or deseases and 27 lines had a facultative resistance to three pests or diseases . Above resistant lines were screened to be expected to provide new resistance resources for rice breeding.
