OK, gave my friend Orchardman a quick call (found him emerging from a nearby telephone booth). He had me Google for Bud 9. He also mentioned rootstock M111 as the favorite for our area. Apparently it depends on the environment and what you want from the tree. He said Bud 9 will get you apples by the 2nd year. I only had a minute but I'm assuming M111 has cold hardiness and heavy soil friendliness as main attributes - - since that is what we have here.

Anyway, the google search turned up a trove of sites (doesn't it always) with lots of information on roots and grafting. Happy surfing.
