摘　　要：通过在河南省南部条锈病流行区连续两年大田调查及对调查资料的聚类分析,对目前河南省主栽小麦品种对条锈病抗性进行评价。结果表明,郑麦9023、豫麦34、小偃54等品种抗条锈病,豫麦47、豫麦70、高优503等品种也较抗病,豫麦18、豫麦69、豫麦54、豫麦62等品种感条锈病,豫麦49、豫麦58等品种高感条锈病。Resistance of major cultivars to Puccinia striiformis(wheat stripe rust,WSR)was studied by randomly sampling in wheat fields in the south of Henan province from 2001to 2002.T he data of investigation were pro-cessed by cluster analysis.The resu lts of analysis indicated that Zhengmai9023,Yumai34and Xiaoyan54were most resistant to WSR;Yumai47,Yuma i70and Gaoyou503took the second pla ce;Yumai18,Yumai69,Yumai54and Yumai62were susceptible to WSR;Yumai49and Yumai58were most suscep tible.
