Distribution of resistant and susceptible trees. The distribution of resistant and susceptible trees is given for (a) each parental haplotype for QTL9.1, and (b) each parental haplotype combination for QTL9.1. The x-axis represents the different haplotypes and haplotype combinations, respectively, whereas the y-axis represents a stacked column representing the proportion of resistant vs. susceptible trees (in percent). From (a) it is clear that the T2 haplotype has more resistant trees (i.e. 82 %) than the other three haplotypes. From (b) considering the parental haplotype combinations, the combination T2-C1 has most of the resistant trees (84 %), followed by T2-C2 (80 %). The numbers in the boxes indicate the number of trees in each class, and the p-values show whether they are significantly different from each other
