Fig. 4From: Genetic diversity, linkage disequilibrium, population structure and construction of a core collection of Prunus avium L. landraces and bred cultivarsDiscriminant analysis of principal component (DAPC) scatter plot of individuals using the 326 SNP set. 20 PCs (Additional file 2: Figure S5) and eight discriminant functions (dimensions) (Additional file 2: Figure S8) were retained during analyses, to describe the relationship between the clusters. The scatterplot shows only the first two PCs of the DAPC analysis. The bottom right graph illustrates the variation explained by the 20 PCsBack to article page
