Principal component analysis (PCA) of the 33L. sativa accessions and three wild species genotyped with 97 genomic SSRs. Color coding for horticultural types is: leaf – yellow, crisp – black, oil – red, romaine and Latin combined – orange, stem – blue, butterhead – green. Insert in the upper right corner shows the relative position of L. serriola (UC96US23), L. saligna (PI 509525), and L. virosa (IVT 280) to the set of L. sativa accessions.
