Variety description

10 August 2026

The plant forms a compact crown up to 3 meters in height and width. Fruit ripening occurs in mid-to-late August, with about 80% of the nuts falling freely from the husk. The nuts are round in shape, have good kernel fill, and are characterized by a low level of mold infection.

The variety possesses genetic resistance to eastern filbert blight due to the presence of the Gasaway gene and also exhibits resistance to the big bud mite. The plant is not self-fertile, carries incompatibility alleles S2 and S10, and due to its short pollen shedding period, requires the selection of additional pollinizers.
