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).

Partly resistant
Nematode Explanations
Has root-knot nematode resistance, but slightly less than Nemaguard. Has greater resistance to ring nematode than Nemaguard and is thus less susceptible to bacterial canker.

Summary Comments
Similar to Nemaguard in many ways but is substantially less susceptible to bacterial canker and Peach Tree Short Life, and is thus widely planted in southeastern USA.

Summary Comments
Has been a standard peach rootstock for many years, but now is not widely used in California because of root-knot nematode susceptibility.

Summary Comments
Main rootstock used in California because it is resistant to root-knot nematode and is compatible with peach, nectarine and plum. It makes a vigorous, productive tree with good fruit size. However, it does not tolerate waterlogged or calcareous soils and is susceptible to many soil pests including ring nematode, bacterial canker and armillaria.
