以冬小麦品种普冰9946为对照，对平凉市农业科学研究所2006 — 2011年引进的108个冬小麦品种(系)进行了叶锈病田间抗性鉴定。结果表明，对叶锈病免疫的品种(系)6个，高抗品种(系)13个，中抗品种(系)22个，中抗及以上抗性水平的品种(系)占鉴定材料总数的38.0%。普遍率≤50%的品种(系)41个，占鉴定材料总数的38%；严重度≤50%的品种(系)78个，占鉴定材料总数的72.2%。

With winter wheat varieties were used as control， resistance of the leaf rust of 108 winter wheats varities were evaluated in Pingliang Institution of Agricultural Sciences， which introduced in 2006 — 2010 years. The results showed that 6 immune varieties (strains)， 13 high resistance varieties(strains)， 22 moderate resistance varieties(strains) on the the leaf rust of winter wheat ，and all of them were accounted for 38%； and 41 varieties(strains) were the disease incidence of the leaf rust of wheat less than or equal to 50% ， accounted for 38%； 78 varieties(strains) were the severity of the leaf rust of winter wheat less than or equal to 50% ，accounted for 72.2%.
