Figure 3 Boxplots representing Tajima’s D distribution for the whole genome (dark colors) or for the candidate genomic regions (pale colors) in all the populations sampled on the susceptible variety (green) and the resistant variety (blue) for the 63 sequenced isolates collected from location 1 in 2011 (A), or for the pool sampled in 2011 (B) and for the pool sampled in 2013 (C). For each population, the two distributions (whole genome versus candidate genomic regions) were compared using a Wilcoxon-Mann-Whitney test and the significance of the p-values is indicated with symbols (***: p-values < 0.001, **: < 0.01, *: < 0.05).
