Variety description

10 August 2026

The variety is a clonal rootstock intended for grafting commercial avocado varieties such as Hass. The plant has medium vigor and a spreading crown.

A key feature of the rootstock is high resistance to Phytophthora cinnamomi, as well as moderate resistance to soil salinity and cold hardiness. However, the plant does not tolerate areas with water stagnation and poor drainage.

The use of this rootstock contributes to increasing the yield of grafted trees and improving their overall condition in commercial orchards.
