由条锈菌（Puccinia striiformis f. sp. triangulae）引起的条锈病和由禾白粉病菌（Blumeria graminis f.sp. triangulae）引起的白粉病是小麦的毁灭性病害。利用成株抗性基因是培育持久抗性品种的重要手段。本研究利用与条锈病和白粉病相关的72个数量性状位点和82个数量性状位点，构建了一张连锁图谱。8个（≥ 5个）基因簇（≥5个）同时对条锈病和白粉病具有抗性，其中1个基因簇（≥5个）对条锈病和白粉病具有抗性，另1个基因簇（≥5个）对白粉病具有抗性。Yr 18/Lr 34/Pm 38、Yr 29/Lr 46/Pm 39和Yr 46/Lr 67表现抗条锈病，叶锈病和白粉病。Yr 18/Lr 34/Pm 38和Yr 36已被克隆，先农4号和小偃6号是重要的抗条锈病和白粉病种质，综述了小麦抗条锈病和白粉病基因在我国小麦育种中的应用，认为利用抗条锈病和白粉病基因将是提高我国小麦抗条锈病和白粉病育种水平的主要途径并讨论了APR在小麦抗条锈病和白粉病育种中的应用策略。
Stripe rust,caused by Puccinia striiformis f.sp.tritici,and powdery mildew,caused by Blumeria graminis f.sp.tritici,are the devastating diseases in common wheat(Triticum aestivum L.) worldwide.Use of adult-plant resistance(APR) genes is an important method for the development of durable resistant cultivars.A total of 72 quantitative trait loci(QTLs) for APR to stripe rust and 82 QTLs for APR to powdery mildew were integrated into a linkage map based on the information of DNA markers linked to individual QTL.Eight gene clusters(≥5 QTLs) conferred resistance to both stripe rust and powdery powdery,among them,Yr18/Lr34/Pm38,Yr29/Lr46/Pm39,and Yr46/Lr67 showed resistance to stripe rust,leaf rust and powdery mildew.Yr18/Lr34/Pm38 and Yr36 have been cloned.Xiannong 4 and Xiaoyan 6 were very important resistant germplasm for APR to stripe rust and powdery midew.The application of APR to wheat breeding in China was summarized.The use of APR genes will be a major method for improving stripe rust and powdery mildew resistance in wheat breeding.The strategies for APR on wheat breeding were also discussed.
