One of the main concerns in field trials of GM crops is transgene escape from GM crops to conventional crops or weedy (wild) relatives via pollen dispersal. The management of field trials is therefore aimed at the detection and prevention of hybridization between GM crops and their closely related species around the field. This study monitored the escape of introduced genes of GM oilseed rapes (Brassica napus) outside the trial site during a small-scale field trial. First, a monitoring area (up to 1.3 km from the isolated field site) was determined according to recommended isolation distances for maintaining varietal purities of oilseed rapes. Then, target species (B. napus, B. juncea and B. oleracea) for monitoring were chosen using a literature search of plant species reproductively compatible with oilseed rapes. Hybrids between GM oilseed rapes and sexually compatible species were not detected and this result indicated that transgene escape outside the trial site did not occur during a field trial.
