摘　　要：2001～2005年，对江苏省水稻区试和预试品种（系）808份进行稻瘟病、白叶枯病和纹枯病抗性鉴定。鉴定结果表明：在被测的各种水稻类型中，籼稻品种（系）对稻瘟病的抗性比粳稻好；在粳稻类品种（系）中杂交粳稻对稻瘟病的抗性叉略比常规粳稻好；粳稻品种（系）对白叶枯病的抗性比籼稻好；常规稻对白叶枯病的抗性明显比杂交稻好；大部分被测水稻品种（系）对纹枯病的抗性较差。The resistance of 808 main rice varieties to rice blast, bacterial blight and sheath blight was assessed and evaluated in 2001 -2005. The resistance of indica rice to blast was better than that of japonica rice, and hybrid japonica rice was better than conventional japonica rice. Japonica rice and conventional rice held the higher resistance to rice bacterial leaf blight than indica rice and hyhrid rice did, respectively. Most of the tested varieties were sensitive to rice sheath blight.
