I'm just an old hobbyist, but there are folks that read what we type that are legends.
I believe the genes required to beat Rose Rosette Disease are in the Native North American Roses.

Hi RBx,

I hope so too. Additionally, R. rugosa seems promising too. There have been some instances some R. setigera plants (that while not overly symptomatic) have tested positive for RRD. Perhaps the virus can still live and multiply to some extent at times in some of these resistant or tolerant roses, but not overtake them too readily. Perhaps such roses could serve as innoculum that mites can spread to the more standard, very susceptible cultivars??
