1Cx DNA-values (medians) of the investigated diploid Malus species. Black line represents the median (0.742 pg) of all 34 investigated diploid Malus species. Malus species having 1Cx DNA-values more than 5% below the median are marked dark grey; species having 1Cx DNA-values higher than 5% above the median are marked light grey. The detailed statistical data are shown in Table 1.
