Genetic relationships within the germplasm collection used in this study. a Principal component analysis (PCA) plot. Different colors represent accessions phenotypically classified as inodorus (orange), ‘carosello’ (green) and ‘barattiere’ (blue). Circles delimit groups corresponding to the subpopulations C, B and I identified by structure analysis (b) Neighbour-Joining cladogram. Accessions assigned to the C, B and I subpopulations are highlighted (red lines). Admixed accessions are indicated with dots. Shaded areas indicate the I genetic clusters including accessions with green and speckled fruit rind and the C genetic cluster encompassing all the accessions collected in Southern Apulia
