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.

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.

In the NC-140 trials Redhaven has been used as the scion variety. Compatability has always been good in these trials. However, many other California varieties have been grafted on Krymsk 1 and many of these show signs of poor compatability. A report from Spain also indicated compatability problems with some varieties.

Summary Comments
In the NC-140 trials, with Redhaven as the scion variety, Krymsk 1 has been very impressive - healthy looking dwarf trees with little suckering, good production and large fruit size. However, many other California varieties have been grafted on this rootstock and most produce weak trees with rolled leaves and poor graft unions.

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.
Other Diseases
Availability from Nurseries
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.
