I just checked Raintree's on-line catalog and it no longer lists as either
Krymsk rootstock as being available. -- Sam Brungardt, St. Paul, Minn. (USDA

If you just want to buy a few--like 5 or fewer, at a standard rootstock
price for a small order, Raintree has Krymsk 1 and Krymsk 5.

Dear group,

Treeconn holds the propagation rights to The Russian Prunus rootstock VVA-1 
Trade Marked as Krymsk-1. It has tested well in US trials. Below is taken 
from a European web site, not the producer's site. 

Krymsk 1 ( VVA-1 cv.) (PAF) (Exclusive to ANFIC)

GENERAL INFORMATION
Pedigree: A hybrid of P. tomentosa x P. cerasifera compatible with peach, 
plum and apricot, reported dwarfing
Origin: Krasnodar region of Russia

CHARACTERISTICS:
Vigor: Dwarfing: approx. 50% of standard
Compatibility: Prunus persica, P.armeniaca, and P.domestica
Suckering: Unknown

ADAPTATION TO SOIL OR CLIMATIC CONDITIONS 
Cold Tolerant
Drought Tolerant
Waterlogging Tolerant
 
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 [Date of this writing is unknown] 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.

Treeconn has given me 25 liners of Krymsk-1 for distribution to NAFEX & 
INGA members. All I ask is the freight. Please limit the number to 5, or
less. 
Organization members will receive priority as well as first come first 
served. Shipping cost will vary depending on location and package. If I'm
swamped 
with requests I reserve the right to select recipients based on locations 
and length of organization membership.
