My recollection from Percy Wright's article in the Pomona is that 
Percy's uncle (who did the test) in B.C. used a prairie bred 
cherryplum, a Prunus besseyi/Prunus salicina hybrid, grafted in the 
top of a peach tree for extra hardiness.

I think it might have been a Sapa or Sapalta but my memory peters out 
about there.

I have been told that NAFEX pioneer Fred Ashworth in northern New 
York State (St. Lawrence County) used to bind the branches of small 
peach trees to the vertical and drop old tires around them for winter 
shelter. I don't recall but would guess that he closed off the top of 
this cylinder as well.
