Population structure in 333 L. sativa and L. serriola accessions. a Principal component analysis (PCA) using the filtered SVs, in which green color represents L. sativa, yellow for L. serriola and gray for admixed samples between L. sativa and L. serriola. b Neighbor-joining tree with branch colors representing L. sativa (green), L. serriola (orange), and admixed samples (grey). c Model-based clustering analysis with different numbers of ancestry kinship (K = 3,5 or 10). Species are indicated in the colored bar at the bottom, with the green color for L. sativa and orange for L. serriola. Geographic groups of L. serriola are indicated in text from central Asia (CAS), the Caucasus (CAU), western Asia (WAS), southern Europe (SEU), and eastern Europe (EEU). Turkish samples and the admixed ones from L. sativa and L. serriola are indicated by arrows
