Peach, plum, apricot rootstock
Exclusive to ANFIC
Pedigree: A hybrid of P. tomentosa x P. cerasifera compatible with peach, plum and apricot, reported dwarfing.
Origin: Krasnodar region of Russia.
Vigor: Dwarfing: approx. 50% of standard.
Compatibility: Prunus persica, P.armeniaca, and P.domestica.
Adaptation to soil or climatic conditions:
- Cold tolerant.
- Drought tolerant.
- Waterlogging tolerant.
- 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 vigorous 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 resistance to nematodes.
