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
A dwarfing rootstock out of the California breeding program that survives well and is compatible with peach and nectarine with no root suckering. It can have smaller fruit size due to high crop loads (heavy flowering) and restricted water conductance (even under well irrigated conditions). It has performed poorly in root-knot, lesion and ring nematode tests (Nematode Table) and a bacterial canker field site (Bacterial Canker Report 2006).

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).

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.

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.
