Discriminant analysis of principal components of six populations (total 323 isolates) of Diplocarpon coronariae based on the allelic information of twelve SSR loci. The first two linear discriminant functions were used for plotting. The analysis was performed on the whole data set (inset panel) and on samples from the European populations only (main plot). Vertical and horizontal jitter (0.2 units each) was applied to draw the data points in order to reduce overplotting
