Barley () is widely cultivated, ranking fourth in cultivation area among cereal crops worldwide. Many wild and cultivated barley accessions have been collected and preserved in crop genebanks throughout the world. Barley has a large genome (~5 Gbp) that has recently been sequenced and assembled at the chromosome level by the international research community. The community also is sequencing accessions representing the diversity of both domesticated and wild barley to provide genome-wide genotyping information for pangenome analysis. Given that the pangenome represents the universe of genome sequences existing in a species, the long-term goal of this project is to obtain high-quality genome sequences of the major barley accessions worldwide. As each accession is annotated, the capacity to explore structural differences is enhanced by the increased understanding of the diversity of the barley genome, which will facilitate efficient development of cultivars for human consumption. This review describes our current knowledge of barley genome diversity and proposes future directions for basic and applied research of the barley pangenome.
大麦（）广泛种植，在全球谷类作物种植面积中排名第四。世界各地的作物基因库已收集并保存了许多野生和栽培大麦种质。大麦拥有庞大的基因组（约50亿碱基对），国际研究团队最近已在染色体水平对其进行了测序和组装。该团队还在对代表驯化和野生大麦多样性的种质进行测序，以提供全基因组基因分型信息用于泛基因组分析。鉴于泛基因组代表了一个物种中存在的基因组序列全集，该项目的长期目标是获得全球主要大麦种质的高质量基因组序列。随着对每个种质进行注释，对大麦基因组多样性的更多了解增强了探索结构差异的能力，这将有助于高效开发供人类食用的品种。本综述描述了我们目前对大麦基因组多样性的认识，并提出了大麦泛基因组基础研究和应用研究的未来方向。
