The Canary Islands are an archipelago that lies about 100 km west of North Africa. Barley (Hordeum vulgare) has been continuously cultivated since the colonization of the islands. To investigate the agricultural history of the islands, the DNA from multiple individuals of six extant landraces of barley was sequenced, and the resulting data were analyzed with ABC modeling. Estimates of separation times of barley populations on the different islands and the mainland were congruent with archaeological dating of the earliest settlements on the islands. The results of the genetic analyses were consistent with the continuous cultivation of barley on Lanzarote island since it was first colonized, but suggested cultivation was carried out at a smaller scale than on Gran Canaria and Tenerife. Contrary to archaeological evidence and early written historical sources, the genetic analyses suggest that barley was cultivated on a larger scale on Tenerife than on Gran Canaria. The genetic analysis of contemporary barley added support to the dating of the colonization of the islands and pointed to the need for more archaeological data concerning barley cultivation on Tenerife.

加那利群岛大麦（Hordeum vulgare）栽培历史的进化方法

加那利群岛是一个群岛，位于北非以西约 100 公里处。自岛屿殖民以来，大麦（Hordeum vulgare）一直在不断种植。为了调查这些岛屿的农业历史，对来自六个现存大麦地方品种的多个个体的 DNA 进行了测序，并使用 ABC 模型分析了所得数据。对不同岛屿和大陆上大麦种群分离时间的估计与岛上最早定居点的考古年代一致。遗传分析的结果与兰萨罗特岛自首次殖民以来一直在继续种植大麦一致，但表明种植规模小于大加那利岛和特内里费岛。与考古证据和早期书面历史资料相反，遗传分析表明，特内里费岛的大麦种植规模比大加那利岛大。当代大麦的遗传分析增加了对岛屿殖民化年代的支持，并指出需要更多关于特内里费岛大麦种植的考古数据。电子补充材料本文的在线版本（10.1007/s10437-020-09415-5）包含补充材料，可供授权用户使用。当代大麦的遗传分析增加了对岛屿殖民化年代的支持，并指出需要更多关于特内里费岛大麦种植的考古数据。电子补充材料本文的在线版本（10.1007/s10437-020-09415-5）包含补充材料，可供授权用户使用。当代大麦的遗传分析增加了对岛屿殖民化年代的支持，并指出需要更多关于特内里费岛大麦种植的考古数据。电子补充材料本文的在线版本（10.1007/s10437-020-09415-5）包含补充材料，可供授权用户使用。
