Summary Comments
This rootstock has looked promising in NC-140 trials. It has survived well and been productive. However, it is a smaller tree than reported from Italy and it appears to be very susceptible to ring nematode, so it could be highly susecptible to bacterial canker as well.

Summary Comments
In Europe, it is reported to tolerate calcareous soils, waterlogging and several soil pests and diseases. However, it was not very impressive in the 2002 NC-140 trial - 3 of the 8 trees died suddenly in one year and suckering was a little excessive.

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
A vigorous rootstock compatible with peach and nectarine that is one of the most resistant rootstocks to bacterial canker (Bacterial Canker Report 2006), even though it is not completely resistant to ring nematode. It is resistant to root-knot and partially resistant to lesion nematode (Nematode Table), similar to Nemaguard.
