小麦新品种中多种抗性源的开发和利用是小麦条锈病持久防治的基础。短句来源本研究在中国小麦选育品系汕麦155中发现了qyrsm155.1和qyrsm155.2两个单株抗病性基因座，qyrsm155.1定位于单核苷酸多态性（SNP）标记sax - 109583610和ax -110907562染色体臂2bl上的3.0 cm区间，qyrsm155.2定位于单核苷酸多态性（SNP）标记sax - 110378556和ax -86173526染色体臂7AS上的2.1 cm区间。一项全基因组关联研究用于鉴定411个春小麦品系中与APR相关的标记。qyrsm155.1和qyrsm155.2分别有13个和11个snp与qyrsm155.2显著相关，对应的物理间隔在2BL为653.75 ~ 655.52 Mb， 7AS为81.63 ~ 83.93 Mb。为了描述这些QTL的单倍型变异和分布特征，我们在全球1101份小麦材料中对这些snp进行了单倍型分析。鉴定出qyrsm155.1的3个主要单倍型（2B_h1、2B_h2和2b_h3）和qyrsm155.2的4个主要单倍型（7A_h1、7A_h2、7A_h3和7a_h4）。单独携带qyrsm155.1 . 1_h1和qyrsm155.2 . _h1单倍型的材料及其组合均表现出抗性。利用qyrsm155.1和qyrsm155.2标记对1306个中国现有品种和选育品系进行分析，结果表明，这两个QTL分别在1.45%和14.16%的品系中存在抗性单倍型。利用标记辅助选择提高这两个位点的抗性单倍型频率将有利于中国小麦生产。
The development and deployment of diverse resistance sources in new wheat cultivars underpin the durable control of stripe rust. In the present study, two loci for adult plant resistance (APR),QYrSM155.1andQYrSM155.2, were identified in the Chinese wheat breeding line Shaanmai 155.QYrSM155.1was mapped to a 3.0-cM interval between the single-nucleotide polymorphism (SNP) markersAX-109583610andAX-110907562on chromosome arm 2BL.QYrSM155.2was mapped to a 2.1-cM interval flanked by the SNP markersAX-110378556andAX-86173526on chromosome arm 7AS. A genome-wide association study was used to identify markers associated with APR in a panel of 411 spring wheat lines. Thirteen and 11 SNPs were significantly associated withQYrSM155.1andQYrSM155.2, respectively, corresponding to physical intervals of 653.75–655.52 Mb on 2BL and 81.63–83.93 Mb on 7AS. To characterize the haplotype variation and the distribution of these QTL, haplotype analysis was performed based on these SNPs in an independent panel of 1101 worldwide wheat accessions. Three major haplotypes (2B_h1,2B_h2, and2B_h3) forQYrSM155.1and four major haplotypes (7A_h1,7A_h2,7A_h3, and7A_h4) forQYrSM155.2were identified. Accessions individually harboringQYrSM155.1_h1andQYrSM155.2_h1haplotypes and their combination displayed resistance. Additional assays of 1306 current Chinese cultivars and breeding lines using markers flankingQYrSM155.1andQYrSM155.2indicated that the resistance haplotypes of the two QTL were present in respectively 1.45% and 14.16% of lines. Increasing resistance haplotype frequencies at these two loci using marker-assisted selection should benefit wheat production in China.
