(A) Representation of the position, the frequency and the type of 45 SNPs from 776 accessions used for haplotype clustering. (B), (D), and (E) Haplotype network analysis of the ten (B) most frequent groups of a 7 kb FLM genomic region based on 45 SNPs or the ten (D) or eleven (E) largest haplotype groups when only SNPs of intron 1 (HI1; D) or introns 2–6 (HI2-6; E) are considered. Circle sizes and the color code illustrate number of accessions in each group with group 1 representing 174 (B), 220 (D) and 356 (E) accessions, respectively. In (B), bolt numbers indicate groups from which representative accessions were chosen. (C) Geographic distribution of the ten most frequent groups of a 7 kb FLM genomic region. (F) Venn diagram indicating the overlap of accessions included in the ten largest HI1 and HI2-6 haplotype groups. (G) Clustering of the haplotype groups of the 589 accessions included in the ten largest HI1 and HI2-6 haplotype groups. Accessions were sorted according to their HI1 and HI2-6 haplotype group numbers. Numbers on the left indicate the HI1 haplotype group number as also shown in (D). An enlargement of a subset of accessions highlighted by the dotted boxes is shown on the right. The color coding for haplotype group numbers, which illustrates the group number and group size as shown in (D) and (E) is specified below the graph.
