Increases fruit size and yield with strong root system. Performs well on replant sites.


Krymsk® 99 (USPPAF)

Is a semi dwarf rootstock for plum and apricot. It induces good fruit size and heavy early production. It is also resistant to nematodes, bacrtrial canker, and many other diseases. Cold hardy and adapts to may soil types. 

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. 

Marianna 26-24

Shallow roots. Good vigor, although tends to slightly dwarf trees. Wide range of soil and moisture types. Common for heavy soils that tend to be wet. Heavy suckering.

Induces early bearing, tolerant of wet soil conditions, resists root knot nematode, advances maturity and increases size and sugar content of fruit.

Contoller 6

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.
