Comparative genetic map of genome-wide association (GWA) and previously detected linkage quantitative trait loci (QTL). The comparative genetic map was constructed from the projection of the consensus map from Hamon et al. [43] onto the consensus map from Tayeh et al. [49]. Linkage groups (LG) are named from I to VII and their size is indicated in cM Haldane. Resistance-, earliness- and height- associated markers, LD blocks and QTL are indicated in red, blue and black, respectively. To the right of each LG: Names of significant trait-associated markers identified by GWA study are indicated. The shading in the LG bar represents the confidence intervals around the significant trait-associated markers, based on linkage disequilibrium (LD) value of r 2  > 0.2. Symbols shown on the right of each marker and described in the legend indicate trait(s) to which the marker was significantly associated. Sign width is proportional to the significance level (p-value) of the marker-trait association. Names of LD blocks are indicated to the extreme right of each LG. The brackets indicate markers that were attributed to a same LD block (r 2  > 0.2). LD blocks labelled by double and single asterisks correspond to consistent (at least two significant markers with P < 5E-10) and highly significant but not consistent (one significant marker with P < 5E-10) blocks, respectively. Genomic positions of cloned pea genes are indicated in grey. The resistance genes cluster identified by Tayeh et al. [49] is represented by light grey shading on the bottom of LGIII. To the left of each LG: Projected QTL and Meta-QTL described in [41, 43] are represented with the same colour trait codes as for markers detected by GWA study. Solid bars represent Meta-QTLs [43], while hatched bars represent initial QTL before meta-analysis [41, 43]. The main Aphanomyces resistance QTL and Meta-QTL [43] names are in bold italic
