Characteristic Detail Description
Rootstock G.11

Resulted from a cross of M.26 and  Robusta 5 crabapple and introduced in 1993 by the New York State Agricultural Experiment Station, Geneva, NY.  G.11 is one of the more vigorous dwarfing rootstocks and produces a tree similar in size to M.26. It is precocious (similar to M.26), moderately resistant to fire blight, moderately susceptible to woolly apple aphid and crown an root rots, and requires trunk support, especially in the early years. It produces few burr knots and root suckers. G.11 has not been widely tested and is being evaluated in an NC-140 trial that was established in 2010.
