Variety description

10 August 2026

The tree of this variety is vigorous and upright; thorns may be found on the strongest branches. The variety is late-ripening, with a harvest period extended into the summer months. The plant is characterized by high productivity and rapid yield onset.

The fruits are round or slightly oval, have thin, smooth peel and a subtle navel characteristic of the group. The pulp is bright orange, juicy, with a good balance of sugars and acids. The fruits are firmly attached to the branches and are able to retain their commercial quality during the summer period, while possessing a low tendency for dryness at the end of the season.
