We can speak a little bit from experience over the last twenty-some years or so. In the wheat field, I was given some numbers. Around only 2% of varieties have been deregistered during that period of time. This isn't a situation that has been identified as a problem to us in that way. You have the two regimes operating at the same time, variety registration and UPOV plant breeders' rights, and we just aren't seeing this issue.
