Summary Comments
A dwarfing rootstock out of the California breeding program that survives well and is compatible with peach and nectarine with no root suckering. It can have smaller fruit size due to high crop loads (heavy flowering) and restricted water conductance (even under well irrigated conditions). It has performed poorly in root-knot, lesion and ring nematode tests (Nematode Table) and a bacterial canker field site (Bacterial Canker Report 2006).

Propagation Methods
Can be propagated by softwood and hardwood cuttings. Now mostly propagated by micropropagation.
Summary Comments
Has been widely used in Europe because of its tolerance to calcareous soils. However, it has many drawbacks including susceptibility to most soil pests and diseases and it does not tolerate waterlogged soils.
