Collection profile

About the Hass cultivar

Hass is the leading commercial avocado cultivar worldwide. It is generally described as a Guatemalan–Mexican hybrid with type-A flowering, a spreading canopy, and fruit that develops a distinctive dark, pebbled skin as it ripens. Its rich texture, eating quality, and strong post-harvest performance have made it the principal reference for international avocado production and research.
