ATP's inclusion of a search option for rust resistance or susceptibility seems to be unique, and this builds a lot of trust and admiration ... in an effort to add something useful to such a great site and super members, I'd like to start working on slowing adding to the handful of DL varieties in the database that have been proposed as being less or more resistant. Rather than reinvent the wheel, tough, I thought it best to check with more knowledgeable folks to see if there is already a central database or list that is kept accessible on the web? I can see that Gulf Coast Daylily Society of Southeast Texas and Texas A&M have done some very good work, and there is a lot of in-garden reporting going on informally, but I haven't been able to find anywhere else like ATP to do a search and get an up-to-date collective list.
If there is such a list, it would be great to hear about it (a search through the forum's posts does not reveal one being identified). Tree mail is fine, if you prefer not to post publicly on the subject. The more you love a plant/flower, the more you tend to shepherd it ... but it is not always a comfortable or easy road to travel.
