Geneva 41 is a highly productive dwarfing apple rootstock, similar in size to M.9, but with much better disease resistance, particularly to fire blight and Phytophthora. It is known for promoting early and heavy bearing, making it a preferred choice for high-density orchards focused on maximizing yield. G.41 has good tolerance to replant disease and woolly apple aphid. Its combination of disease resistance, early productivity, and dwarfing nature makes it a top choice for commercial apple growers aiming for efficient, high-yield production systems.
