Clustering of rye individuals based on multilocus analysis using STRUCTURE. Accessions are organised by taxa. Each individual is depicted by a vertical line segmented into K coloured sections. The length of each section is proportional to the estimated membership coefficient (Q) of the individual accession to each one of the K clusters. Thin black vertical lines separate different accessions and thick ones separate different taxa. Labels on the x axis indicate accession numbers. a K= 9 model for the complete set of accessions, including the two S. strictum accessions that were later removed from the accession panel (PI 240285 and PI 531829). b) K = 4 model for the wild and feral rye accessions. c) K = 5 model for cultivated rye landraces. d) K = 7 model for the Southern set of Moroccan, Portuguese and Spanish landraces. e) K = 4 model for the Northern set of Fennoscandian and Russian landraces
