Like Jan, I am not as concerned with rust resistance because of the obvious reasons, I barely get rust. Also, without rust resistance ratings (which are finally being looked at on daylilies), one would not know when hybridzing which ones are resistant or not. If they don't have a rust rating then you cannot very well breed for rust resistance. Bud count is important to me and I will not keep a seedling under a 15 bud count, unless it is exceptional and I think I may be able to use it as a bridge plant with a cultivar with a lot higher bud count.
