Abstract
Understanding the gene flow from genetically modified (GM) crops to conventional crops is important to prevent and mitigate seed contamination caused by pollen-mediated gene flow. We conducted a field test to investigate the gene flow from diamondback moth resistant GM cabbage (Brassica oleracea var. capitata) containing cry1Ac1 gene, to a non-GM control line AD126. GM and non-GM cabbage plants were cultivated in the field and pollinated using Bombus terrestris under the nets during the flowering periods. After seeds were collected from non-GM plants, hybrids between them and the GM cabbages were screened by multiplex PCR targeting cry1Ac1 gene. Out of 878 germinated seedlings, 168 hybrids were found and the average gene flow frequency was 19.7%. Because cabbage is mainly pollinated by insect pollinators, large-scale field tests are needed to study gene flow of GM cabbage.
