Resistant / tolerant to
Resistant against fire blight and Phytophthora

Research shows that there are indications that compared to the M9 T337*, possibly a  higher production can be realized with the CG11 rootstock.

Because of the resistance against fire blight and phytophthora, the CG11 rootstock is a welcome addition for cultivation areas that face problems with fire blight.

At this moment there is ongoing research to further substantiate the advantages of the CG11 rootstock. We gladly answer any of your questions about the CG11 rootstock and / or the available sorting’s.
