湖北省小麦后备品种及二线育种材料抗病性鉴定

Resistance Identification of Promising Wheat Cultivars and High-Generation Materials in Hubei Province

为筛选较好的综合抗病性材料和为品种审定提供依据,2007年度在病害鉴定圃对22个小麦区试后备品种及71份二线育种材料进行了田间抗赤霉病、白粉病、条锈病和纹枯病的多抗性鉴定。结果表明,没有发现对白粉病和条锈病免疫的品种,大部分品种综合抗病性不强,仅发现1份既抗赤霉病、又抗白粉病和条锈病,有11份同时抗两种病害,分别占鉴定材料总数的1.1%和11.8%。

To screen good resistant materials and provide useful information for varieties release, 22 promising wheat varieties and 71 high-generation materials were identified with fusarium head blight, powdery mildew, stripe rust and sharp eyespot in filed in 2007. The results showed that no immunity material had been found to resistat against powdery mildew and stripe rust. Most materials had less comprehensive resistance. One material were found to anti-three and eleven anti-two pathogens at the same time, which accounted for 1.1% and 11.8% respectively.
