Duke 7
Duke 7 outperforms other local rootstocks and was South Africa’s industry standard.
Hass
Hass is the most common commercial avocado cultivar in the world. It is known for its good eating quality and post-harvest characteristics.
Pinkerton
The Pinkerton is green-skinned with a pear shape. It is known for its prolific yields and mild, nutty flavour.
Edranol
Edranol is a vigorous-growing cultivar with pear-shaped avocados that are medium in size with thin, rough, green skin.
Zerala™
Zerala™ rootstock is resistant to Phytophthora cinnamomi and offers a noticeable advantage in saline soils. It supports large canopy volumes and competitive yields, preferring well-drained soils or berms.
Uzi
Uzi is an extremely vigorous and fast-growing rootstock with high tolerance to Phytophthora cinnamomi. When grafted with Hass in a low salinity environment, it can induce a vigorous tree and high yields.
Carmen®-Hass
