在田间，用１５个具有不同毒性基因组合的叶锈菌系混合接种在３７个小麦品种（系）上，分析了品种成株期慢锈特性。并通过病害潜育期（ＬＰ）、流行速率（ＥＲ）、病程曲线下面积（ＡＵＤＰＣ）、侵染型（ＩＴ）、夏孢子堆显症率达５０％所需的有效积温（ＡＴＬＰ５０）等抗性组分的相关分析和品种的聚类分析，初步筛选出荆州２３４、荆州２３６、荆州２３９、绵阳２６号、绵优１号、绵优２号和８１８ＩＮ９８等７个具有明显慢叶锈性的品种（系）。发现在病害发生有利的环境条件下，终期病情指数（ＦＤＲ）小于０．３０和夏孢子堆显症率达５０％所需的有效积温相对值（ＲＡＴＬＰ５０）大于１．２０在很大程度上可代表品种慢叶锈抗病性，似可作为小麦品种慢叶锈选育的重要指标。
In the field, 15 rust traits with different combinations of virulence genes were inoculated on 37 wheat cultivars (lines), and the rust trait of adult varieties was analyzed. The antimicrobial activity of ATLP50 was determined by the following parameters: disease latent period (LP), epidemic rate (ER), area under the curve (AUDPC), infectious type (IT) The correlation analysis of sexual components and the cluster analysis of cultivars showed that seven of them with obvious slow leaf rust were screened initially, including Jingzhou 234, Jingzhou 236, Jingzhou 239, Mianyang 26, Mianyou 1, Mianyou 2 and 818IN98 Variety (Department). Found that the relative effective accumulated temperature (RATLP50) required for a FDR of less than 0.30 and a 50% incidence of nymph sporulation was greater than 1.20 for a favorable disease environment Can represent the slow leaf rust resistance of varieties, it may be used as an important indicator of wheat leaf blight rust selection.
