Fig. 4From: Use of easy measurable phenotypic traits as a complementary approach to evaluate the population structure and diversity in a high heterozygous panel of tetraploid clones and cultivarsInferred population structure. Bar plot based on 4859 Single Nucleotide Polymorphism (SNP) markers generated by STRUCTUREÂ 2.3 using the admixture model. Each colour represents a cluster (KÂ =Â 5). Each column (183 columns in total) represents a potato genotype, which is partitioned into segments. Each segment represents the estimated contribution of the participating genetic background (cluster). The a priori groups are indicated capital letters (A-H) as described in Table 1Back to article page
