Figure 2.

Principal coordinate analysis of 46 tritordeum lines based on the H. chilense and D-genome polymorphic DArT markers. The diagrams show the positions of individual accessions in the space spanned by the first two coordinates. The genetic composition of the lines is shown as follows: triangle: DS 5D (5Hch); square: double DS2D (2Hch) and 5D (5Hch); star: DS2D (2Hch); circle: DS1D (1Hch); inverted triangle: DS 6D (6Hch) and diamond: euploid tritordeum.
