Pearson’s r (below the diagonal) and Spearman’s rank ρ (above the diagonal) correlation coefficients between the pvr2³ resistance breakdown frequency (RB) and four variables linked to evolutionary forces characterizing Potato virus Y (PVY) populations in the different pepper genotypes: the differential selection (σ _r), effective population size during plant colonization (N _e), effective population size at inoculation (N _e ^inoc) and viral accumulation (VA). Correlations that are significant with both Pearson’s and Spearman’s coefficients are shaded in grey.
