Variety description

10 August 2026

The plant is vigorous, reaching a height of 2.5–4.5 meters, with a spherical crown. The variety is self-incompatible; for cross-pollination, the varieties «Wepster» and «McDonald» are recommended. The nuts have a nearly round shape, small or medium size, and a thin shell, which facilitates mechanical processing.

The kernel yield is about 47–48%, and the pellicle is easily removed during blanching. The variety is resistant to Eastern filbert blight due to the presence of a specific dominant allele. It exhibits good drought tolerance and heat tolerance.
