Rootstock | G.214 | Geneva 214 (G.214) is a cross of Robusta 5 x Ottawa 3 and tested as CG.4214. Trees on this rootstock will need to be supported and produce a tree about 30-35% size of seedling with vigor and precocity similar to M.9 Nic.29 and M.26. Trees are more productive than those rootstocks and have good cold hardiness, and are resistant to fire blight, Phytophthora root rot and wooly apple aphid.
