Principal Coordinate Analysis of the Eulycopersicon sample with Structure2.0 clustering information. The 'red-fruited' sample did not contain S. cheesmaniae accessions. The subdivision of the collection assuming Kopt = 2 separates group 1 (triangle) and group 2, (square) accessions. When assuming Kopt = 4, large fruited accessions: subgroup D (black square) and small-size fruit accessions: subgroup C (white square) are divided. For wild accessions, subgroup A (white triangle) and subgroup D (black triangle) were divided. 'Wild'/'domesticated' admixed accessions are represented by grey diamonds. Intra-specific admixed accessions are not identified. Inertia values are 22.09% and 4.84% for factorial coordinates axes 1 and 2, respectively.
