Origin
Geneva^® 30 was developed by Cornell University/Geneva Apple Rootstock Breeding Program and originated from a cross of 'Robusta 5 X M-9'.

Influence on Scion Habit
Trees On Geneva^® 30 are M-7 size and are planted in the same density as M-7.  Support is not required and it seem well suited to vertical axis training.  Geneva^® 30 show to be very winter hardy with extremely high yield efficiency, about 3-5 times better than M-7.

Disease Resistance
Geneva^® 30 is resistant to fire blight (Erwinia amylovora) and has a high tolerance for crown rot.  Burrknots are rare and it is more broadly adaptable to soil conditions.

Nursery Habit
Geneva^® 30 produces an abundance of spines that must be rubbed off in the stoolbed or cut off before planting.  They also require more side limbing by the nurseryman than is welcomed.

Horticultural Value
Geneva^® 30 is similar in many respects to M-7 but superior in almost all important characteristics.  It is more precocious and more productive.
