Population structure analysis of the cultivated and landraces stevia inferred using the model-based program STRUCTURE at K = 3. a Proportions of ancestry of cultivated and landraces Stevia rebaudiana accessions (n = 145) inferred with STRUCTURE for K = 3. Each individual is represented by a vertical bar, partitioned into colored segments in proportion of the estimated membership in the different genetic clusters inferred with STRUCTURE. Under the figure are depicted the two groups of genotypes cultivated (CULT) or landraces (LR) and color and names of the three clusters. b Neighbor-Joining dendrogram based on DICE dissimilarity indices showing the relationships among the nonadmixed 126 Stevia rebaudiana individuals (i.e. individuals assigned to one cluster at K = 3 with a membership coefficient > 0.80). Genotypes were colored according to their assignment to the three different genetic clusters, as inferred by STRUCTURE. Branch length is proportional to the distance between nodes
