Last year I root grafted a couple varieties of pear on the Smokey variety of 
amelanchier, was delighted and surprised with the growth.
I do not know how to determine what is the variety of craetagus we have 
locally, but so far my grafts of apple and pear have failed.
3 years ago I grafed several local chokecherries with p. maritima - beach 
plum. Even in the partial shade it has just this week flowered profusely, 
and is quite healthier than the mother plant - which is in full sun on heavy 
soil. So the buds of p.maritima have gone through minus 40F and come out 
happy - I didn't think it would be that hardy.
Glad to hear of your pear rootstock breeding Dean.
