为避免基因推导的简单化以及增强基因推导的准确性，本研究利用多菌株分组，在不同环境条件下（温室和人工气候箱），用直接比较法在不同年份对同一批小麦品种进行了抗叶锈基因推导，结合系谱分析，在１０个小麦品种中得如下结果：京农８６－１６１和京农８６－６５５４含有Ｌｒ２６；Ｈ８８－６５含Ｌｒ１５和Ｌｒ２６；唐麦４号、京农８６－７４和农大８４０１６含Ｌｒ２６和另一个未确定的抗性基因；京农８９－Ｓ４０６９和太原１６３所含的抗性基因与供试的已知Ｌｒ基因不同；在京４１１和太原７６８中不含抗性基因
In order to avoid the simplification of gene deduction and enhance the accuracy of gene inference, the present study utilized multiple strains to classify wheat cultivars in different years under different environmental conditions (greenhouse and artificial climate chamber) with direct comparison Derived from leaf rust genes, combined with pedigree analysis, the following results were obtained in 10 wheat varieties: Jingnong 86-161 and Jingnong 86-6554 contain Lr26; H88-65 contain Lr15 and Lr26; Tangmai 4 and Jingnong 86- 74 and Nongda 84016 contained Lr26 and another unidentified resistance gene. The resistance genes contained in Jingong 89-S4069 and Taiyuan 163 were different from those of the tested Lr genes; they were not resistant in Jing 411 and Taiyuan 768 gene
