Where is the best place to get OHxF97 ? Sounds like great way to go on rootstock!

Willamette was the source for OHxF 97. I switched from Pyrus communis for this full-sized vigorous stock based on recommendation of Fedco.

For slow to bare E. plums citation can be helpful, not so much for Js.

Apples are a lot about your space allotment and patience for fruit. My workhorse is 111 because I like to grow trees and leave a legacy. Some varieties are greatly slowed from fruiting by this rootstock but it is not a problem for the likes of Goldrush, Ark Black, Ginger Gold, Honeycrisp and other less vigorous, early fruiting varieties.

I don't think you need to be stuck on the Cornell rootstocks if you can't find them. If you need fairly dwarfing but want trees that can eventually support themselves M26 will probably be fine in your zone.

Don't forget that the vigor of the variety has as much affect as relative vigor of the rootstock.

I use G6 for cherries and haven't needed to stake them although I do have a couple of leaners at windy sites- never had one blow over, even at sites where unstaked apples on M7 fall like dominoes.

Most of my apples were on B118 with a few M7. 100 Montmorency Cherries were mostly on CT500 Mahaleb, planted this spring. I did try grafting Montmorency onto Krymsk 5 (last spring). Of the 10 I grafted I had 6 take and only one of them survived the winter. All of my meteor on mahaleb and 7 out of 10 balatons on mahaleb survived the winter right next to the Mont on Krymsk.. I had -15f this winter but I would not have thought that would have been a problem for Krymsk.

Thanks everyone for the comments I always learn stuff from you guys. I have been using callery for pear rootstock , 111,wild apples ,antonovka for my apples. Manchurian for my apricots and the cherries I got from lawyers but the name escapes me right now because they are new to me. I'm trying Hansen cherries, American plum , Canadian bounty plum, goose plum, wild unkwown purple plum and sand plum for my test plum rootstock this year.

Can't speak from experience but if you are in Z5, I expect Cally will be killed in a true winter- it is considered only hardy to --10F.

In the old days I've read New England growers successfully grew pears on quince by burying the tree well below the graft union. I don't know if they pulled away the soil during the growing season so scionwood would not root, but that's what I'd do if I wanted a dwarf tree- obviously it wouldn't be necessary with Callyrana, unless you just wanted to be sure roots got enough oxygen.

Here is a link that might be useful: pear rootstocks

I've heard that harvestman and these have taken -20 already. I read that on a website and expected it 10 or so years ago but it's just not been the case here with these types.

Apples I like G.11/M.111 interstem.

Milehighgirl,
I intended to get g11 this year because they produce quick but how do you feel about steaking them? I figured for a few it's ok but for a lot it would be a lot of extra work. How in general are they working for you?
