摘　　要：叶锈病是小麦生产中的重要病害,培育持久抗性品种可以有效控制该病害。本研究以抗病品种莱州137、感病对照品种郑州5389、慢锈性品种SAAR以及36个已知抗叶锈病基因的载体品种为材料,在苗期和成株期进行了2年2点的接种鉴定,通过系谱分析、基因推导和12个与抗叶锈病基因连锁的分子标记检测,发现莱州137携带Lr26、Lr10、Lr14b以及其他未知抗叶锈病基因,且表现成株抗性的特点,说明其可能含有未知的成株抗性基因,可作为新的小麦抗叶锈病抗源加以利用。Leaf rust is an important wheat disease which has a great influence on yield. Breeding for durable re-sistant cultivars can effectively and economically control the disease. In the present study, the cultivar Laizhou 137,susceptible control Zhengzhou 5389, delayed rusting cuhivar SAAR and 36 donor lines were tested for leaf rust re-sistance at the seedling and adult plant stage during the 2014-2015 and 2015-2016 cropping seasons. The gene pos-tulation, markers-assisted detection in combination with pedigree analysis showed that Laizhou 137 contained Lr26,LrlO, Lr14b and additional unknown resistance genes ; and it had unknown adult-plant resistance gene because of ex-pressing slow rusting resistance. Therefore, this line can be new resistant resource and utilized for wheat breeding.
