Figure 3. Distinguishing populations based on GWAFFs.

Figure 3

Principle Component Analysis (PCA) of GWAFFs based on SNP positions having a minimum coverage of 5 in all samples. (A) and (C) GWAFFs based on allele frequencies of the variant allele at 21,942 SNP positions in ApeKI, (B) and (D) GWAFFs based on allele frequencies of the variant allele at 10,958 SNP positions in PstI. Colours in A and B correspond to the varieties; Beatrice (black), Chardin (Green), Stolon (grey), Greenway (sky blue), Glenveagh (dark blue), Sponsor (yellow), Mongita (purple), and Bronzyn (red). Colours in C and D correspond to type; forage (black), turf (red).
