Hi folks,

I am attempting to propagate a very good apple variety I discovered at a SW Virginia homestead.

I grafted it to 1 Bud9 dwarfing rootstock and it is healthy and vigorous. On the 3 M111 grafts I have, it is alive, but struggling. Small sample size, but I am struck by the difference.

I found:
*b. Interclonal (between clones) / intraspecific*
Interclonal / intraspecific compatibility (/among apples/ /Ed./) is the rule rather than the exception.

From: https://courses.cit.cornell.edu/hort494/mg/specific.grafting/compatibility.html

Has anyone observed apple graft incompatibility?

Is M111 known to be problematic?
