The varieties of plants that are reliable for transformation are not the ‘latest and greatest’ varieties that farmers want to grow in their fields. In order to move the gene into these elite current varieties, breeders cross with the elite line over and over again. This process is called backcrossing. Learn more about this process in the videos below.
Additionally, learn more about the time-frame of developing a new transgenic plant compared to more traditional breeding methods from the animation linked below. NOTE: This is a Flash based animation and therefore may not be viewable on all mobile devices. Follow this link to use the animation
