Resistant / tolerant to
Resistant against fire blight, phytophthora and red mites. Tolerant for rep;antation disease.

The G41 rootstock realize a higher production compared to the M9 T337 with comparable fruit weight and vigor-levels and with a higher percentage well colored fruits *.

Because of the resistance against fire blight, phytophthora and red mites, and the additional reduced sensitivity for replantation disease combined with a higher production, it seems that the odds are high for the CG41 rootstock.

The G41 rootstock has a good winter hardiness, which makes it also suitable for regions with more severe winters. At this moment there is ongoing research to further substantiate the advantages of the G41 rootstock.

We gladly answer any of your questions about the G11 rootstock and / or the available sorting’s.
