First of all, let me start by saying that I love the fact that anyone can "discover" a new variety of plant, regardless of genus. With dogwoods, it is exciting to find new varieties to choose and grow, since seedlings seem to exhibit a fair amount of diversity. Having said that, I am wondering if some kind of reasonable standard needs to be implemented regarding the issuance of patents for said new cultivars. A case in point, drawn from a previous thread: Cornus kousa 'Satomi' and Cornus kousa 'Heart Throb' appear, based on DNA evidence, to be either identical or extremely closely related. Who then, now controls how this (these) cultivar(s) are propagated? As growers go forward with new introductions, should DNA fingerprints be included as a condition of the patent process, and should new plants be clearly different from known cultivars in the nursery trade? It only seems fair. Any thoughts?
