Those in Zone 4 who really like peaches and are on well-drained sandy 
soil might want to see if they like the mandschurica/armeniaca cross 
prairie-hardy apricots, like Westcot and Morden 604. They might only get 
a crop 2 years out of 5 but that's better than nothing, and they are a 
pretty tree.

Those on heavier soil could try St. Julien A rootstocks if they have 
reliable heavy snow cover.

Or they could experiment with the compatibility of Krikon Damson roots 
or interstems, or Yellow Egg (might be marginally hardy) interstems on 
hardy plum stocks. Pershore Yellow Egg is considered compatible with 
apricot in Britain, and I presume that the North American Yellow Eggs 
are related, though that is certainly not conclusive.

And, if you haven't considered quality plums and you can handle black 
knot, you should think about plums, maybe start with Mount Royal (hardy 
to about Agriculture Canada zone 4a). Commercial plum growers, for 
respectable commercial reasons, insist on picking plums unripe. If you 
haven't eaten a properly ripened high-quality plum (and I expect that 
most beginning home growers haven't) you don't know what you're missing.

The Minnesota station had Krikon Damsom (still popular in Sweden, 
possibly hardy to about 3b, at any rate a little hardier than Mount 
Royal) around 1950 and perhaps they still do. I think Agriculture Canada 
still has it in their collection.
