Population structure analysis. Results are shown for the minimum number of subpopulations (K) which sufficiently define genetic variation, as inferred by the estimation of the ΔK parameter. Each individual is represented by a vertical line, which is partitioned into coloured segments whose length depends on the estimated membership fraction (q) in each subpopulation. Individuals are assigned to a specific subpopulation when the highest q is higher than 0.6 (a) Genetic structure of the C. melo germplasm collection used in this study. The subpopulations I, C, and B, which refer to the types inodorus, ‘carosello’ and ‘barattiere’, respectively, are indicated. b Genetic structure of the subpopulation I. The three subgroups are named Y, G and S as they contain accessions with yellow, green and speckled fruit rind, respectively
