Ginda:Ed,
Viruses are transmitted in various ways other than traditional
grafting/budding and
pruning. Any sucking incest can likely transmit most viruses with
leafhoppers
being likely the most successful. Also nematodes can transmit viruses by
feeding on roots.
While apparently not a problem with apple orpear, some viruses are
transmitted via pollen
or the pollen is a vector in stone fruits.
Also, naturally occurring root grafts (roots of near by apples, for
example)
can transmit viruses.
And of course that is the beauty if the older rootstocks. Enough
time/exposure has
occurred to learn which of those are tolerant and those that are not.

One of the most interesting typos I have ever seen.
