摘 要：
对湖北省2006-2011年687份水稻区试品种(系)进行田间病圃自然诱发抗稻瘟病鉴定。鉴定结果表明,表现抗病的品种(系)占4.08%,表现感病的品种(系)占95.92%,感病品种(系)所占的比例大于抗病品种(系)。区试对照材料的感病率为98.75%,每年感病对照材料稻瘟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)抗稻瘟病鉴定奠定了基础。研究明确了近年来湖北省水稻区试品种(系)的抗稻瘟病现状及发展趋势,可为水稻新品种的合理布局和抗稻瘟病育种提供参考。

摘 要：
The resistances to rice blast of 686 rice varieties planted in Hubei province under the condition of nature induc- tion was identified and evaluated from 2006 to 2011. The results showed that the resistant varieties accounted for 4.08% while the susceptible varieties accounted for 95.92%. The proportion of susceptible varieties is greater than that of resistant varieties. The susceptible rate of control materials in regional test is 98.75%. The resistance of susceptible control materials reached the levels of susceptible or high susceptible with the stable morbidity every year, providing foundations for identifica- tion of rice varieties' resistance to rice blast. The current situation and the trend of development of the rice varieties ' resis- tance to Rice Blast in the six years was explicited, which may offer a reference for reasonable layout of new rice varieties and blast-resisting breeding in Hubei province.
