Figure 2

Estimated population structure of the tomato genotypes. Each genotype is represented by a horizontal line, which is partitioned into colored segments that represent the estimated membership fractions in the K clusters. A) Population structure inferred using the whole SNP dataset for K = 7. B) Population structure inferred using the non coding SNPs for K = 7. C) Population structure inferred using the coding SNPs for K = 10. See Additional file 7: Figure S1 for the determination of the most informative K value.
