First, I would just like to clarify that the Canadian Seed Trade Association makes no claims about transgenic being any better than conventional varieties. Our members are actively involved in producing and distributing and selling both transgenic and non-transgenic varieties. Further, I think on the analogy you gave of being able to plant your own seed, that option certainly still exists for farmers in that we do still have conventional varieties available, open pollinated in crop types, with the exception of hybrids in corn, but in corn that's not really related to the transgenic issue. Certainly open-pollinated options are still available, but in the majority of cases where transgenic products are available, those are the ones that generate a higher profit for farmers, so that's what they elect to plant.
