Heatmap correlation between the Zymoseptoria tritici isolates tested under field and controlled conditions on the ‘Agili39’/Khiar mapping population performed using the “Corr” function and visualized using the “corrplot” package in the R environment [42, 43]. Different traits are named by the isolate followed by the Necrosis (N) or pycnidia (P) development at the seedling stage (S). Isolates tested at the adult plant stage are followed by the term field, and the RILs advanced generation (F6 – F10). Colours gradient is an indication of high (red colour) and low (blue colour) correlation between traits
