Krymsk® 86 (USPP# 16272)
Peach/Plum hybrid with amazing root strength and outstanding anchorage. Tree size similar to Lovell with a wide spreading root
system. Tolerant to wet and heavy soils. Cold hardy and high PH tolerance. Most popular almond rootstock for the Sacramento
Valley. Nonpareil compatible.
Roots tend to be intermediate depth, good vigor. Medium to heavy soil. Wide range of soil and moisture types. Less suckering
than Marianna 26-24. Susceptible to Bacterial canker.
Very tolerant of wet soils, induces early dormancy in dry soil. Very winter hardy. Resists root-knot nematodes. Includes heavy
bearing at a young age.
Controller 6 is a peach rootstock with medium vigor. It has moderate resistance to root knot nematode, low suckering, size control
ability, and less wood from dormant and summer pruning.
M40 Marianna (USPP# 11403)
It has been observed that Marianna M40 has good wet soil tolerance, with the potential for better anchorage and reduced sucker
production. The M40 may eventually displace 26-24 and other plum rootstocks.
