Cornell University / USDA-ARS, USA, 2005
Developed by the Cornell-Geneva program by crossing 'Ottawa 3' with 'Robusta 5', Geneva 935 (G.935) is a high-performing semi-dwarfing rootstock. It produces a tree roughly 45% to 50% the size of a standard seedling—slightly larger than M.26. Growth practices require permanent trellis support due to heavy early crop loads, though it exhibits better natural anchorage than M.9 clones. G.935 is exceptionally precocious and yield-efficient. Notably, it offers excellent resistance to fire blight and Phytophthora root rot, along with good tolerance to Apple Replant Disease, but unlike most Geneva clones, it is susceptible to woolly apple aphids.G.935 is notoriously sensitive to latent scion viruses (such as Apple Stem Grooving Virus). You must only graft certified virus-free budwood onto G.935; grafting virus-infected wood can cause graft union failure or tree decline.
