摘要
为了给水稻品种在生产栽培上的合理布局和品种搭配提供依据,2005年和2006年对贵州省湄潭县部分主栽水稻品种对稻瘟病的田间抗性进行了鉴定。结果表明,在湄潭县推广的22个水稻品种中没有表现抗病的品种出现。最好的抗性表现也只达到中抗,其中福优325和川香优6号的抗性水平相对较好(2年均为中抗),其抗性比较稳定,可在稻瘟病综合防治中作为抗病品种布局搭配种植。
The rice blast resistance of main rice varieties was identificated to provide the basis for the rational distribution and combination of rice varieties in rice production during 2005-2006 in Meitang county, The results show that all tested rice varieties have no resistance to rice blast and express the poor comprehensive resistance to rice blast. The resistance to rice blast of Fuyou 325 and Chuanxiangyou 6 is the middle level and stable resistance, which can be used in rice production for comprehensively controlling rice blast.
