大麦是研究世界重要作物进化、适应和传播的模式物种。在这篇文章中，我们描述了寡核苷酸池分析单核苷酸多态性（SNP）平台的首次应用，以评估农业发展的关键区域新月沃土的一部分大麦的进化。在来自约旦和叙利亚的地理上匹配的地方品种和野生大麦种质（N= 448）中分析了> 1000个遗传映射的全基因组SNP的大集合。 地方品种和野生大麦类明显的遗传分化，但有限程度的二次接触是显而易见的。在已知参与品种进化的基因周围，观察到大麦类型之间多样性的显着染色体水平差异。与叙利亚北部相比，约旦和叙利亚南部地区更有可能是驯化起源。·我们的数据提供的证据杂交作为一种可能的机制，继续适应栽培条件下的地方品种大麦，表明区域的基因组，可能会受到选择过程，并建议有限的起源发展的栽培作物。
•Barley is a model species for the investigation of the evolution, adaptation and spread of the world’s important crops. In this article, we describe the first application of an oligonucleotide pool assay single nucleotide polymorphism (SNP) platform to assess the evolution of barley in a portion of the Fertile Crescent, a key region in the development of farming.•A large collection of > 1000 genetically mapped, genome‐wide SNPs was assayed in geographically matched landrace and wild barley accessions (N= 448) from Jordan and Syria.•Landrace and wild barley categories were clearly genetically differentiated, but a limited degree of secondary contact was evident. Significant chromosome‐level differences in diversity between barley types were observed around genes known to be involved in the evolution of cultivars. The region of Jordan and southern Syria, compared with the north of Syria, was supported by SNP data as a more likely domestication origin.•Our data provide evidence for hybridization as a possible mechanism for the continued adaptation of landrace barley under cultivation, indicate regions of the genome that may be subject to selection processes and suggest limited origins for the development of the cultivated crop.
