Abstract: Engineered genes in transgenic crops may escape into the ambient environment via crop‐weed hybridization However, natural crop‐weed muting rates (gene flow) are largely unknown. We measured mating between wild and cultivated radishes in an experiment that simulated natural stands around seed multiplication plots. We used a genetic marker to identify, crop‐weed muting events. Although weeds at the cultivar plot margin (1 m distance) received much more gene flow than distant plants, detectable gene flow occurred at our most distant site (1000 m). For insect‐pollinated outcrossing crops like radish, strategies other than distance must be employed to ensure complete isolation.
