Fig. 1

Pedigree of the progenitors in the F252 and MBS DSEs. Each dot represents one progenitor, from generation G0 to generation G16. Pedigrees of generation G16 are shown in black. At each generation, 100 selfing progenies from each progenitor were evaluated, and between 0 to 3 were selected to constitute the progenitors of the next generation. Note that 11 progenitors were selected at generation G15 in the Late F252. At generation G16, each DSE encompasses two Early and two Late families that were derived independently since generation G0, except for the Late F252 population, for which the two families were derived since generation G4
