1982—84年对本所现有的992份稻种资源分期分批进行了抗白叶枯病的人工接菌鉴定。其中国外稻种448份,省外稻种327份,本省育成品种(系)及地方品种217份。接种菌源为本所植保室提供的X01—2菌株(致病力中等的南阳湖菌系)。筛选出了一批高抗白叶枯病的稻种资源。 In 1982-84, the existing 992 rice germplasm resources in our institute were identified by artificial inoculation against bacterial leaf blight. Among them, 448 were from foreign paddy rice, 327 from paddy rice from other provinces, and 217 were from bred varieties (lines) and local varieties from the province. Inoculation of bacteria-based plant protection provided by the X01-2 strain (moderate pathogenic Nanyang Lake strain). A number of rice germplasms resistant to bacterial blight were selected.
