   Hi,

         It's hard in Canada (my part at least) to source rootstocks. 
However, I have found a source for
   Siberian Crab ( malus baccata) and Royalty Crab.

      [1] Siberian crab - my research indicates that this rootstock is 
extremely hardy  more so that Antonovka, - which is good because I will 
be planting
            the clones in a zone 3 - 4 area). However, I have read that 
there is "compatibility" issues with this rootstock -
            but no one ever says how serious this may be or what 
particular varieties will not work with m. baccata.
  
               Any information on m. baccata as a roostock , especially 
about the compatibility issue will be appreciated.

       [2] Royalty crab - how suitable is this rootock for grafting, 
especially for zone 3/4 planting?

                       Thanks,

                       Peter Drevniok
