Geneva 210 is a semi-dwarf apple rootstock known for its excellent resistance to fire blight, one of the most destructive diseases in apple orchards. It also provides resistance to woolly apple aphid and has good tolerance to replant disease, making it a valuable choice for replanting in old orchard sites. G.210 promotes moderate tree vigor and produces a tree slightly larger than M.7. It performs well in a wide range of soil types and supports high fruit production, making it an ideal rootstock for commercial orchards requiring disease resistance and consistent yields.
