Resumen: Landraces are described as genetically diverse, dynamic populations of unimproved crops. However, studying the development of a landrace population over longer periods of time has rarely been done due to a lack of suitable archaeological materials. The indigenous grain silos of Gran Canaria provide a unique opportunity for genetically analysing multiple specimens from the same time period as well as sampling the same population at multiple time points. Here we report a genetic study of a landrace barley (Hordeum vulgare L.) sampled repeatedly over a period of 1400 years. We successfully enriched extracted aDNA for the barley exome using capture techniques and present sequencing data from ten archaeological and six extant samples. The results show that the landrace barley population of Gran Canaria has not undergone any dramatic genetic turnover or influx of new genetic material since the 7th century CE, but that the scale of cultivation seems to have varied. We detect smaller temporal changes of the genetic composition during the studied period and suggest that these changes reflect natural selection for adaptation to a changing climate and a dynamic agricultural society.
