Graphical representation of Multiple Factors Analysis (MFA) of the phenotypic data. Correlation circle of variables (coloured according to groups) (a) and genotype factor map (coloured according to origin) (b), on the first two principal components of the MFA of disease variables. Earliness and height variables are supplemental variables and thus are projected onto the dimensions but were not included in the analysis. All the variables are abbreviated as described in Table 1. GSP0-3: lines from the GSP breeding program containing in their pedigree zero to three of the previously described major sources of resistance (PI180693, 90–213 and 552) [43] (Additional file 1), respectively. Parents: Parental lines of GSP breeding programs and/or RIL populations. BRILs iia, iib, iic: Selected lines from the Baccara x PI180693, Baccara x 552 and DSP x 90–2131 RIL population, respectively; New sources: Selected accessions from the large INRA screening program; Varieties: Registered dry pea varieties. Extreme genotypes are labelled on the two main principal components
