An inventory of crop wild relatives and wild-utilized plants in Canada

This dataset first includes an inventory of crop wild relatives and wild utilized plants in Canada. The inventory was assembled by identifying plants that occur in Canada that are congeneric with food crops of agricultural importance and/or are utilized directly. During the inventory assembly process we collected and add to the inventory dataset information on breeding utility that is available through the GRIN-Global Crop Wild Relative Database (https://npgsweb.ars-grin.gov/gringlobal/taxon/taxonomysearchcwr) and on conservation threats that was requested and provided by NatureServe Canada (https://www.natureserve.org/canada). Next, we downloaded occurrence data from the Global Biodiversity Information Facility (GBIF.org) to map the occurrence range for each plant taxa in the inventory. These data are used to identify ecogeographic regions with high crop wild relative diversity. For each crop wild relative in the inventory, we then downloaded accession data from Canadian genebank system databases and the database for the genebanks of the US NPGS system. We also contacted major Canadian botanical gardens, requesting full collections data from seven botanical garden institutions, which was then filtered to find accessions matching the taxa in our inventory. Using the collections data, we identify the number of accessions representing each taxon in the inventory. We then combine the collections data with the ecogeographic occurrence data to identify the proportion of within species ecogeographic diversity (as a proxy for within-species genetic diversity) that is represented for each taxon in genebank and botanical garden conservation systems. Finally, we provide a supplemental web application to enable readers and interested parties to view breeding utility, conservation threats, ecogeographic range, and ex situ conservation status on a taxon-by-taxon basis.

本数据集首先收录加拿大境内作物野生近缘种与野生利用植物名录。该名录通过筛选分布于加拿大境内、与具有农业重要性的粮食作物同属，或可直接被开发利用的植物汇编而成。在名录汇编过程中，我们收集并录入了可通过GRIN-Global作物野生近缘种数据库（GRIN-Global Crop Wild Relative Database，https://npgsweb.ars-grin.gov/gringlobal/taxon/taxonomysearchcwr）获取的育种利用相关信息，以及由加拿大NatureServe（NatureServe Canada，https://www.natureserve.org/canada）提供的物种保育威胁数据。随后，我们从全球生物多样性信息设施（Global Biodiversity Information Facility，GBIF.org）下载物种出现记录数据，以此绘制名录中各植物类群的分布范围，进而识别作物野生近缘种多样性较高的生态地理区域。针对名录中的每一种作物野生近缘种，我们分别从加拿大种质库系统数据库与美国国家植物种质系统（US NPGS）的种质库数据库下载种质登录样本数据。此外，我们联系了加拿大境内的主要植物园，向7家植物园机构申请获取完整的馆藏采集数据，并经筛选匹配到名录中对应类群的样本。依托这些馆藏数据，我们统计了名录中各分类单元对应的种质样本数量。随后，我们将馆藏数据与生态地理分布数据相结合，以物种内生态地理多样性（作为物种内遗传多样性的替代指标）的占比，评估各分类单元在种质库与植物园保育体系中的迁地覆盖程度。最后，本数据集附带一款补充网页应用，供读者及相关利益方逐类群查询育种利用价值、保育威胁情况、生态地理分布范围以及迁地保育现状。
