Characteristic Detail Description
Rootstock P.2

Resulted from a cross of M.9 x Common Antonovka and released by the Research Institute of Poland in Skierniewice, Poland. This is a productive, cold hardy, dwarfing rootstock slightly more dwarfing than M.9 NAKBT-337. It is susceptible to fire blight, and wooly apple aphid, but fairly resistant to crown and root rots. It produces few root suckers and burr knots similar to M.9. In NC-140 trials trees survive; depaending on location tree size was similar to or up to 30% smaller than trees on M.9 NAKBT-337. Trees on P.2 often had yield efficiency slightly higher than trees on M.9 NAKBT-337.
