Disease Explanations
Several scientific studies show this rootstock to be resistant to some diseases such as bacterial canker and crown gall. However, in the California 2002 NC-140 trial, several trees died suddenly in the middle of the season, probably from a disease.

Propagation Methods
Easy to propagate by layering, hardwood cuttings and micropropagation
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.
