I don't have any experience with such a project but, like most of us
amateurs, I'm always ready with an opinion: I think it makes sense, M
robusta 5 has been used by Cummins as a parent due to its hardiness, woolly
apple aphid resistance, and other factors if I recall. I wonder if he
considered some of the natural dwarfs as roostocks, some of them may not
have been out when he began his breeding. I do seem to recall that Meteor
cherry has been used as a hardy semi dwarfing stock for sweet cherry and
sour cherry, so why not use nat semi dwfs with apples? It can't be that hard
to get a few scions to root and do some experiments, (or can it?) if you
would like to coordinate something like that with me let me know.
PS, I've seen a Kerr that was about 20 ft tall in N Dakota so I don't think
that would be the best one to start with. Most of the naturally dwarfing
apples seem to be naturally SEMI dwarf around 12 - 15 feet.
PS Are you aware of Malus micromalus? It has been sold for many years by
wholesalers but I have never heard of anyone trying it.
Also, Beautiful Arcade might be worth some trials here, there should be
plenty of info from Canada on that one where it has been used for some
Don't know nuttin about sergenti or pumila.
I am wondering if anyone has any experience with or opinions about using
dwarfing seedling apple crab "species" such as Malus kerr, pumila, or
rootstock to impart dwafing and maintain hardiness. These are reasonably
sargentii is something like a 10 foot shrub. Will grafting cultivars onto
seedlings impart these desired characteristics?
