There is a clone of butternut called "Iroquois" from Eastern Ontario which is reported to have some resistance to butternut canker. I don't knoiw anything about the details.

"Iroquois" is propagated and sold by Grimo Nut Nursery in the Niagara Peninsula:

I bought a vigorous butternut/white walnut seedling today. I just read up on
the disease susceptibility in white walnut. There is a 300+ historic white
walnut that near me. It looks in good shape, although has a large cavity in
it's trunk at the base, but still doing well. Does this mean that this is a
tree of unusual disease-resistance?

Should I graft a disease-resistant scion/cultivar unto it?

Are there disease-resistant clones?
