Pollen-Mediated Movement of Herbicide Resistance Between Commercial Canola Fields (original) (raw)

This study investigates the movement of herbicide resistance via pollen from genetically modified (GM) canola crops to non-GM varieties. Conducted across a commercial landscape involving over 48 million individual plants in Australia, it quantifies the actual gene flow. The findings reveal that while pollen-mediated gene flow occurs, the resistance levels observed in non-resistant varieties are generally low, with maximum resistance frequencies reaching 0.197%, primarily in fields located close to the GM source.
