COMMENTS:
Is looking very good in the trials for peach, plum, nectarine, and apricots. Is very dwarfing at least 50%. Fruit size is very good better than Lovell on young trees. Some incompatibilities are reported in Spain with low chill nectarines. We have never seen any incompatibilities.
The rootstock is adaptable to many soil types including heavy soil. It does not resist stress well and can have a problem with transplant shock if not handled well. Requires good irrigation practices or the trees will be very dwarf. Seems susceptible to Pseudomonas. Good yield efficiency.

USA: 4-5 years of observations in California; + Compatability; ++ enhancement of fruit size; Compatible with Elegant Lady but not Fairtime; + suckers; Apricots have a good balance of renewal growth; 10% more vigourous than Torinel and other apricot rootstocks; Larger fruit of Japanese plums compared to Citation; strong point for plums.

HOLLAND: Main strength of Krymsk 1 is with plums; Holland has 14 years data; 60% of full tree size; increased fruit size; less dwarf with plum than peach; works great with flowering plums; could be the best apricot rootstock, check compatibility but it occurs early; a large % of Czech varieties are okay; susceptible to bacterial canker (although never seen in the field); some resistence to nematodes.
