Summary Comments
A standard rootstock for more northern peach growing areas because of good cold tolerance. However, it is susceptible to root-knot nematode and offers no advantages over Nemaguard.

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.

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
Being evaluated in the 2009 NC-140 trial. After 4 years, it has survived well, looks healthy with no suckers, and makes a standard size tree. Otherwise, we have little experience with this rootstock.

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.

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.
