I have never tried breeding any plants before to be perfectly honest, but I plan on starting a small scale breeding program with some plants that are native in my area. Now, I don't genuinely expect to create a proper cultivar but I want to know if there is a way to protect new breeds from becoming heavily commercialized. I am not necessarily opposed to commercial usage of new plant breeds, but I would want to structure it as closely to the plant equivalent of the GNU public license as possible. I don't want to breed a plant and then have that plant used for making a commercial variety that no one has access to. All I really want to do I ensure that if anything I breed does end up having some success, that a company can't use it to make their own proprietary cultivars.
