This misunderstanding is based on the assumption that the seed developer has achieved the goal as soon as they know the gene and can deliver it into the plant, where as conventional breeding can take generations to achieve a goal because of the need to eliminate undesirable traits. So can yo give us an example of a trait that was brought about quickly by conventional breading, and a similar trait that was delayed by GM? Fact: After fifteen years of research and development experience, it has become apparent that genetic modification can increase development time. Development time of what? Have two identical traits been developed by conventional and GM techniques so this comparison that you claim can be made? The necessary laboratory work is complementary to, not a substitute for field breeding work. The actual plant breeding work in genetically modified varieties is the same as for conventional varieties, but before this breeding work can start, there is the need for extensive molecular development. It is generally more expensive to develop genetically modified varieties and bring them to market than conventional varieties, because of the additional research and development work, and additional regulatory requirements. But this has little to do with speed -- your original claim. |
