对水稻白叶枯病采用抗病品种,似乎是目前最为经济有效的防治措施。国内外对选育抗白叶枯病品种的研究极为重视,并已收到了良好的效果。 我们从1973年开始,先后对一千多个原始材料进行了抗白叶枯病鉴定,从中鉴定出南粳15、7276、红芒3号、双丰4号、贵州麻谷、IR26等30多个抗病较好的品种。从这些品种接种后较迅速地发生褐色的坏死型病斑分析,它们 The use of disease-resistant varieties of rice bacterial leaf blight appears to be the most cost-effective prevention and treatment measure. At home and abroad, the research on the breeding of bacterial blight resistant cultivars has attached great importance and has received good results. Since 1973, we have carried out the identification of bacterial blight resistance on over one thousand raw materials, identifying more than 30 such as Nanjing 15,7276, Hongmang 3, Shuangfeng 4, Guizhou Magu, IR26 etc. Disease resistant varieties better. Brownish necrotic lesions were detected more rapidly from these varieties after inoculation, and they were analyzed
