Population structure analyses of 207 genotypes in the Merge set based on the high-resolution 4475 SNPs assessed by STRUCTURE (http://pritch.bsd.uchicago.edu/structure.html). (A) Determining delta K values for different populations (K = 2) or 3 clusters (K = 3). (B) Bar plot for the K value 2 or 3. Population structure analysis was performed using admixture 1.343. Color segments represent different groups inferred by STRUCTURE analysis.
