Variety description

10 August 2026

The plant provides moderate vigor; trees on this rootstock are approximately 40% shorter than on the GF 677 rootstock. The rootstock promotes early entry into fruit-bearing, increased yields, and also improves fruit size and coloration.

It possesses good resistance to chlorosis and is adapted to fertile, permeable soils due to a well-developed root system. It is propagated via micropropagation, while it is difficult to propagate by cuttings or layering.
