^aModels tested with fastsimcoal2 are listed in three columns divided by topology and ranked from the most to the least likely. Basic_tree1 (column 1), basic_tree2 (column 2) and basic_tree3 (column 3) indicate the topologies shown in figure 2a–c, respectively. The suffixes intro and mig indicate that introgression or migration was modeled between the two lineages reported at the end of the model name (0 = B.g. tritici1, 1 = B.g. tritici2, 2 = B.g. secalis, 3 = B.g. dactylidis), the suffix H indicate a hybridization model in which B.g. tritici1 originated from a hybridization between B.g. tritici2 and an unsampled lineage. The best model is highlighted in dark grey.

^bLog-likelihood of the model.

^cNumber of parameters of the model.

^dAkaike information criterium.
