Number of intra-chromosomal marker-pairs in the total population and in the two groups, respectively.

<p>Unlinked refers to a marker-pair distance >50 cM.</p

Estimation of the number of groups based on output from STRUCTURE-software.

<p>A: ΔK over K from 2–10 with the whole marker set of 1,849 markers B: ΔK over K from 2–10 with the reduced marker set of 695 markers.</p

Mean r²-value for the significant and non-significant intra-chromosomal marker-pairs in the total population plus the two groups (GrI and GrII) found in the population structure analysis.

Principal component analysis of 92 hexaploid wheat genotypes.

<p>Based on analysis of 695 polymorphic DArT markers. Numbers refer to the genotypes described in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0094000#pone-0094000-t001" target="_blank">Table 1</a>. Closed circles: GrI. Open circles: GrII. <b>A:</b> Colored according to geographical origin. North: Sweden, Denmark, Germany and UK. <b>B:</b> Colored by the band size of the <i>Rht8</i> marker Xgwm261.</p

Origin (Ori) of the 94 genotypes, Belgium (BE), Canada (CA), Germany (DE), China (CH), Denmark (DK), France (FR), England (UK), Hungary (HU), Italy (IT), Luxembourg (LUX), Netherlands (NL), Poland (PO), Ukraine (UKR), Sweden (SE), USA (US), Bulgaria (BU).

<p>Year refers to the first year in official trials. Empty cells: year unknown. ID refers to ID in PCA-plot (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0094000#pone-0094000-g004" target="_blank">Figure 4</a>). NG refers to no genotype data.</p><p>*Breeders varieties and lines have not been assigned accession number. Seeds are available from breeders on request. Some varieties were obtained from IPK gene bank (Gene bank Information System of the IPK Gatersleben) and accession-ID is given in brackets.</p>A<p>Spring variety.</p

Linkage disequilibrium versus chromosome position on 2D.

<p>The two upper panels display r²-values for adjacent marker-pairs along chromosome 2D. The LD between pairs of adjacent loci is plotted at the locus nearest to zero. GrI and GrII indicate the two population subgroups. The lower panel shows the positions of individual markers on chromosome 2D. Markers with high contributions to subgroup separation are shown in red.
