GENE TRANSFER FROM GENETICALLY MODIFIED CROPS
The report, which is based on a desk study of a substantial quantity of previously published research in related areas, considers all the routes by which the mixing of organic and genetically modified crops may occur, including pollen transfer and the growth of volunteers. It concludes that no system for the field production of seed can guarantee absolute genetic purity of seed samples. Very rarely, long-distance pollen transmission or seed transfer is possible and any criteria for organic crop production will need to recognise this.
