摘 要：
对湖北省2005-2012年918份水稻区试品种(系)进行田间剪叶接种抗白叶枯病鉴定。结果表明,抗病的品种(系)占9.37%,感病的品种(系)占90.63%,感病品种(系)占的比例大于抗病品种(系)的比例。区试对照材料感病率为95.33%,每年感病对照材料对白叶枯病发病均能达到感病或高感水平,且发病稳定,这为水稻区试品种(系)抗白叶枯病鉴定奠定了基础。本研究明确了近年来湖北省水稻区试品种(系)的抗白叶枯病现状及发展趋势,可为水稻新品种(系)的合理布局和抗性育种提供参考。

摘 要：
The resistances of 918 rice varieties planted in Hubei province to bacterial blight were identified and evaluated under field inoculation in 2005-2012. The results showed that the percentage of resistant varieties was 9.37%. Percentage susceptible varieties was 90.63%. The proportion of susceptible varieties was more than that of resistant varieties. The morbidity of control materials in regional test was 95.33%. The resistance of susceptible control materials reached susceptible or highly susceptible levels with the stable morbidity. It laid foundations for identifying resistance of rice varieties to bacterial blight. The condition and developing tendency of the resistance rice varieties to bacterial blight during the eight years was clarified. It will provide reference for the reasonably layouting new rice varieties and breeding rice variety with resistance to bacterial blight in Hubei province.
