Summary Comments
Slightly dwarfing rootstock from the California breeding program that is compatible with peach and nectarine with no suckering. Trees have been productive with good fruit size. Nematode tests (Nematode Table) show root-knot and ring suseptibilty, but better resistance to lesion nematode than Nemaguard. Performed poorly in bacterial canker field site (Bacterial Canker Report 2006). |
