The CG 41 rootstock gives a higher vigor (+25%) compared to the M9 T337.
|Indication mapping of the vigor from B9 rootstock|

|M9 T337 / B9||40%|
|M9 FL 56||35%|
Resistant / tolerant to
Resistant against fire blight, phytophthora and red mites. Tolerant for rep;antation disease.
The CG41 rootstock possibly seems to 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 CG41 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 CG41 rootstock.
We gladly answer any of your questions about the CG11 rootstock and / or the available sorting’s.
