Rootstocks

Bud-10® produces trees that are 30% to 35% of seedling and a tree similar to Pajam 2 in climates like Eastern Washington. Bud-10® has vigor similar to M9-337 and Pajam®2 in climates like New York. It is said to have yields similar to that of M9-337; shares the same cold hardiness and blight resistance to that of Budagovsky 9. Upon a 10-year trial in Pennsylvania with Golden Delicious as the scion cultivar showed that trees on this rootstock were similar in size to trees on G.935 and M.9 T337 (15 percent smaller), yet more robust than its' counterpart of Budagovsky 9.

This M9-337-size root is very productive, showing higher yield efficiencies than many commercial roots, including M9 trials. Suckering is light and susceptibility to woolly apple aphid is moderate. It does not show resistance to replant disease.

This dwarfing rootstock of Belgian origin produces a tree slightly more vigorous than M9-337. The root system is more expansive and fibrous than the M9-337. Tree support is required.

Ideal for high-density plantings. Performs similar to EMLA 9, cropping early with large fruit size. Best production occurs on fertile, well drained soils with consistent moisture. Brittle roots and poor anchorage necessitate tree support.

This dwarfing, M9-size rootstock is very resistant to collar rot and moderately resistant to powdery mildew and scab. Superior winter hardiness has increased grower awareness. Tree support is required.

A new release from Cornell University, this rootstock is similar in size to Nic 29 in Washington and Emla 26 in New York. It is highly resistant to woolly apple aphids, fire blight, crown rot, and replant disease complex. It is also winter hardy and more productive than standard M-9.

A new release from Cornell University, this rootstock is similar in size to EMLA 7. It is replant disease tolerant and highly resistant to woolly apple aphid. It makes an excellent replacement for GENEVA® ‘G.30’. Availability is very limited at this time.

A new release from Cornell University, it is highly precocious with a strong graft union. GENEVA® 'G.969' is similar in size to EMLA 26 or smaller in Washington State while exhibiting a more vigorous quality in New York conditions. It is highly resistant to woolly apple aphids and replant disease complex. Availability is limited at this time.

Released in 2005, GENEVA® 'G.935' is a dwarfing rootstock that is resistant to Fire Blight and Crown Rot and is similar in size to M9-NIC29. It appears to have good graft union strength but given its heavy cropping, tree support is recommended. The rootstock is susceptible to woolly apple aphid, but has shown tolerance to replant disease. GENEVA® 'G.935' is susceptible to latent viruses, requiring the use of certified virus clean scion material.

This release from Cornell University’s rootstock program is creating strong interest with growers. It produces a tree similar to M9 with better productivity. Branch angles tend to be naturally flatter and the selection is very winter hardy. It is highly resistant to woolly apple aphid and has shown tolerance to replant disease.
