The problem for me isn't if the lily is virus tolerant or not, but that I - as a buyer - rarely or ever is informed if it is or nor. All you usually get is a pretty picture and no info about resistance/tolerance to virus and fungal diseases.
Kordes does this quite well with their roses in regards to black spot and mildew. They are specifically growing resistant varieties and informing their buyers. It's a very good sales argument! One could only hope that some of the big lily companies would go for more resistant cultivars as well. I'm not saying that they don't try, probably there is better incentive to do so with stricter environmental regulations today as compared to the past, but where is the info? Certainly not in most sales catalogues...
