Biotypes of Avena fatua resistant to ACCase-inhibiting herbicides have been reported in the States of Baja California (BC) and Sonora (SON), Mexico. We hypothesised that resistant biotypes present in SON (Valle de Hermosillo and Valle del Yaqui) are derived from a resistant population from BC (Valle de Mexicali) via gene flow through the transport and exchange of contaminated wheat seed. This study aimed to determine (1) the resistance of A. fatua to ACCase-inhibiting herbicides in populations from BC and SON, (2) the mutation at the site of action and (3) the genetic structure and gene flow among populations.
