Résumé
Genome editing has been shown to have the potential to accelerate genetic gain, and some simulation studies in animal populations have also demonstrated the potential of editing quantitative traits. This approach could also be beneficial for perennial tree species, which generally have a long breeding cycle. To assess the potential of genome editing for such species, we simulated a poplar breeding program based on recurrent genomic selection to investigate the impact of (i) the number of edited parents, (ii) the number of edited QTLs, and (iii) the method to choose the parents on genetic gain and inbreeding.
