摘要

关键信息:在春小麦 PI 660072 的 2BL 和 4BL 染色体上绘制了抗条锈病的两个主要 QTL,并开发了它们的 KASP 标记。由条锈病菌(Puccinia striiformis f. sp. tritici,Pst)引起的条锈病是全球小麦最具毁灭性的病害之一。鉴定抗性基因对于培育抗病品种以控制该病害至关重要。春小麦 PI 660072(Triticum aestivum)已被确定具有对条锈病的成株抗性(APR)和全生育期抗性(ASR)。为了阐明 PI 660072 抗性的遗传基础,从 PI 660072 与易感春小麦 Avocet S 的杂交中培育出了一个由 211 个 F5-F7 重组育种系(RIL)组成的测绘群体。从 2020 年到 2022 年,对该测绘群体在五个田间环境中的条锈病反应进行了表型分析,并使用 15 K SNP(单核苷酸多态性)阵列进行了基因分型,以绘制条锈病抗性位点图。此外,还在温室中用主要的中国 Pst 株系 CYR31、CYR32、CYR34 和 PST-YX1-3-1 对制图群体进行了苗期测试。利用数量性状位点(QTL)作图法确定了条锈病抗性基因。确定了两个 QTL,QYrPI660072.swust-2BL 映射在 ASR 的 2B 染色体长臂上,QYrPI660072.swust-4BL 映射在 APR 的 4B 染色体长臂上。为促进标记辅助选择育种,开发了竞争性等位基因特异性 PCR(KASP)标记,即 QYrPI660072.swust-2BL 的 KASP-1269 和 QYrPI660072.swust-4BL 的 KASP-3209。这些标记可用于将有效抗性 QTL 导入新的小麦栽培品种。

Genome-wide mapping of quantitative trait loci conferring resistance to stripe rust in spring wheat line PI 660072.

Key message: Two major QTL for resistance to stripe rust were mapped on chromosome 2BL and 4BL in spring wheat PI 660072, and their KASP markers were developed. Stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is one of the most devastating diseases of wheat worldwide. Identifying resistance genes is crucial for developing resistant cultivars to control the disease. Spring wheat PI 660072 (Triticum aestivum) has been identified to possess both adult-plant resistance (APR) and all-stage resistance (ASR) to stripe rust. To elucidate the genetic basis of the resistance in PI 660072, a mapping population consisting of 211 F5-F7 recombinant-inbred lines (RILs) was developed from a cross of PI 660072 with susceptible spring wheat Avocet S. The mapping population was phenotyped for stripe rust responses across five field environments from 2020 to 2022 and genotyped using the 15 K SNP (single nucleotide polymorphism) array to map stripe rust resistance loci. The mapping population was also tested at the seedling stage with predominant Chinese Pst races CYR31, CYR32, CYR34 and PST-YX1-3-1 in the greenhouse. Stripe rust resistance genes were identified using the quantitative trait locus (QTL) mapping approach. Two QTL were identified with QYrPI660072.swust-2BL mapped on the long arm of chromosome 2B for ASR and QYrPI660072.swust-4BL on the long arm of chromosome 4B for APR. To facilitate marker-assisted selection breeding, Kompetitive allele specific PCR (KASP) markers, KASP-1269 for QYrPI660072.swust-2BL and KASP-3209 for QYrPI660072.swust-4BL, were developed. These markers could be used to introgress the effective resistance QTL into new wheat cultivars.

期刊介绍: Theoretical and Applied Genetics publishes original research and review articles in all key areas of modern plant genetics, plant genomics and plant biotechnology. All work needs to have a clear genetic component and significant impact on plant breeding. Theoretical considerations are only accepted in combination with new experimental data and/or if they indicate a relevant application in plant genetics or breeding. Emphasizing the practical, the journal focuses on research into leading crop plants and articles presenting innovative approaches.
