Variety description

10 August 2026

The tree has medium vigor, forming a wide, spreading crown with drooping branches, reaching a height of 6–7 meters. The variety is distinguished by early fruit-bearing; the first nuts may appear in the second year after planting.

The nuts ripen in mid- to late September. The nuts are of medium size and oval shape, featuring a very thin shell that is easy to crack. The kernel is sweet, accounts for about 50% of the nut weight, and turns light brown to brown in color upon drying.

The variety is characterized by high winter hardiness, but shows sensitivity to late spring frosts. Resistance to anthracnose and bacterial blight is rated as medium. The nuts are suitable for fresh consumption and the confectionery industry; the variety can be used as a pollinator.
