Variety description

10 August 2026

Trees grafted on this rootstock occupy an intermediate position in vigor between trees on standard seedling rootstocks and quince rootstocks. The root system is characterized by rich branching and deep penetration into the soil, which ensures good tree stability.

The rootstock is distinguished by high wood frost resistance and tolerance to high calcium and magnesium content in the soil. It has excellent compatibility with all pear varieties, accelerates the onset of fruiting, and ensures regular yields.

Under nursery conditions, the rootstock exhibits good qualities, including thin bark and a long period of sap flow. The plant is characterized by tolerance to common diseases and pests.
