Summary Comments
This rootstock has performed very well with plums and apricots. With peaches, its performance has been variable. Many trees look great, but others have died or shown other signs of incompatability. About half the trees died in the 1984 NC-140 trial.

In a NC-140 rootstock trial in a calcareous soil in Utah, this rootstock has not survived well, but the surviving trees do not show iron chlorosis.

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).
