Characteristic Detail Description
Rootstock Supporter 1

Resulted from a cross between M.9 and Malus baccata (L.) Borkh. Supporter 1 was tested at seven locations in the NC-140 1999 trial with ‘Fuji’ as the scion cultivar. Supporter 1 trees had good survival and trees were about 75% as big as M.9 NAKBT337, produced similar numbers of root suckers as M.9 and had slightly high yield efficiency than M.9. European tests indicate it is quite cold hardy.
