Fig. 1. Principal components analysis (PCA) showing population structure for M. domestica (N = 749), M. sieversii (N = 115), and M. sylvestris (N = 11).

Fig. 1

A PC axes were established using equal sample sizes (N = 11) of the wild species and the remaining accessions were projected onto the axes. The percent variance explained by each PC is indicated in parentheses. B Comparison of PC1 values for cider and dessert apples demonstrates that dessert apples derive more ancestry from M. sieversii, while cider apples derive more ancestry from M. sylvestris
