Can a crabapple scion graft to an apple rootstock?

Question

Given that apple trees can be pollinated from crabapples are apple rootstocks compatible with crabapple scions also?

Answer 1

Yes, as crabapples and production apples are the same genus and species (Malus domestica). Typically, though, it's edible apples that are grafted onto crabapples. This is often done "high" so that an existing crabapple can become a many-variety production apple tree.
