a Principal coordinate analysis based on pairwise modified Rogers’ distances of 66 landrace-derived DH lines and 65 breeding lines (triangles), including four prominent founder lines (downward triangles). From each of three DH libraries, KE (circles), LL (squares), and PE (diamonds), 22 lines were sampled randomly. Axis labels show the percentage variance explained per principal coordinate. Venn diagram shows overlap of 456,911 haplotypes between 941 landrace-derived DH lines (LR) and 65 European breeding lines (BL). Haplotypes were constructed for nonoverlapping genomic windows of 10 SNPs. b Frequency of 456,911 haplotypes in DH lines (x-axis) and breeding lines (y-axis). Colors indicate the number of haplotypes within each cell of the heat map. Source data are provided as a Source data file.
