Explanations for calcareous soil tolerance - compatiblities - suckering
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.
Resistant or tolerant
California tests (Nematode Table) show susceptibility to root-knot but some resistance to lesion nematode.
Did not survive well in a bacterial canker hot spot in South Carolina
In NC-140 Trials
Availability from Nurseries
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.
