Variation for morphological plant and fruit descriptors across cultivar groups in two locations. Stacked bars indicate the proportion of each class for the considered traits on a total scale 0–1. a-d Plant and flower traits; e-i Fruit traits. Details of measurement scale for each trait are in Supplementary Table 2. Locations: IT = Italy, ES = Spain; Cultivar groups: BL = breeding lines, CL = elite cultivars, LS = long shelf-life landraces, FC = landraces for fresh consumption, HL = heirloom varieties
