Despite being located within a primary region of crop diversity, documentation of Tajik crop and crop wild relative (CWR) resources is far from comprehensive, particularly regarding CWR. Here, we compile the first inventory of food CWR of Tajikistan. A total of 549 food CWR taxa belonging to 36 families and 125 genera were documented as occurring in the country. Among them, 71 taxa were recognized as native close relatives of globally important crops (category 1A), 67 as native distant relatives of these crops (1B) and 411 as native taxa with an undetermined relationship to these crops (1C). This documented CWR diversity far exceeds previous scientific assessments for the country and, in doing so, distinguishes the Tajik region from surrounding countries. Within the country, the results indicate a clear gradient of food CWR taxonomic richness from the eastern part of the country (least diversity) to the western part (greatest diversity). This trend adds important new information to the body of literature published by N. I. Vavilov and others, who mainly stressed the importance of the Pamir region (Eastern Tajikistan) for crop and CWR diversity.

尽管位于作物多样性的主要区域内，但塔吉克作物和作物野生近缘种 (CWR) 资源的记录远非全面，特别是关于 CWR。在这里，我们编制了第一份塔吉克斯坦食品 CWR 清单。共有属于 36 科和 125 属的 549 个食物 CWR 类群被记录在该国发生。其中，71 个分类群被认为是全球重要作物的本地近亲（类别 1A），67 个分类群是这些作物的本地远亲（1B），411 个分类群是与这些作物（1C）关系不明的本地分类群。这种记录在案的 CWR 多样性远远超过了该国以前的科学评估，并且这样做将塔吉克地区与周边国家区分开来。国内，结果表明，从该国东部（多样性最少）到西部（多样性最大），食物 CWR 分类丰富度存在明显的梯度。这一趋势为 NI Vavilov 等人发表的文献增加了重要的新信息，他们主要强调了帕米尔地区（塔吉克斯坦东部）对作物和 CWR 多样性的重要性。
