Each subpanel corresponds to an orchard. From left to right, the first row shows the results of Nova Scotia Bowlby (Canada), Nova Scotia Van Oostrum (Canada), Ontario Jordan (Canada), Ontario Vineland (Canada), Matitya (Israel), Yiron (Israel) and orchard n1 (Italy). The second row shows the results from orchard n2 (Italy), Corbins (Spain), Alcarràs (Spain), Prangins (Switzerland), Etoy (Switzerland), orchard 1 (Turkey), Melilla (Uruguay). The third row shows the results from Montevideo (Uruguay), MRF (NY, USA), RJO (NY, USA), orchard B (Washington USA), orchard Q (Washington USA), AFRS (WV USA), SM (WV USA).
