I have no idea either, but I'd guess it would be individually negotiated between the grower and the seller, so there could be a variety of resolutions to each question. I'm thinking a noted hybridizer might be able to negotiate a more favorable contract than a beginner. But it's all speculation on my part. Also a less worldly renowned vendor might require less than a big well known vendor. Kent might also provide some help here, since he's more recently begun the process.
