摘要：

Engineered genes in transgenic crops may escape into the ambient environment via crop-weed hybridization. However, natural crop-weed mating 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 mating 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.
