Once we obtain an optimized variety, we'll have them reproduce as much as possible, expand the population of the improved variety, and gradually eliminate the old variety.

"However, the earliest sires and dams must also be preserved. Even with an improved variety, no one can say after how many generations their ancestral traits might reappear.
