Number of QTLs identified according to cross or environmental conditions. Panel a. LOD score obtained with SBxGN cross for V50_80. In grey, LOD score for the model with environment as additive variable, in pink, LOD score for the model with environment as interactive variable. The corresponding horizontal colored lines represent the 5% FDR threshold. The table details the QTLs identified by indicating their chromosome (Chr), the position of the marker with the highest LOD score within the QTL peak (Pos), the maximum LOD score within the QTL peak (Lod.score) and the model that detected the QTL (Type, A = additive, I = interactive). Panel b. The Venn diagram presents the number of QTLs identified according to the model used. The All ellipse corresponds to the multi-environmental model while M15, SB14_Sk and M15_Sk ellipses counts QTLs detected only using a single condition. Panel c. The bar chart presents QTLs identified according to cross and trait. Common QTLs identified for t35 g, t50 g, t80 g, V15_50 and V50_80 are pooled in Kinetics category and are counted only as one QTL. QTLs are colored according to the parental strains that possess the favorable allele in an enological context. Panel d. Distribution of the QTLs identified along the genome according to the cross (M2xF15 inner track, SBxGN outer track). Each point indicates a QTL and is colored according to the trait. The two QTLs that colocalize in the two crosses are indicated with a black pike
