Variety description

10 August 2026

The tree is medium-sized, reaching a height of 5–7 meters at 20 years of age. The crown is broadly rounded and of medium density; skeletal branches emerge at an acute angle. Shoots are greenish-brown; leaves are oval-elongated, matte, with wavy margins.

Fruits are oval-oblong in shape, weighing about 8.9–9.0 g, with a thin, smooth, shiny, and sturdy shell. The kernel is white, dry, and dense, containing 69% fat and 18.9% protein. The kernel yield is 48–54%.

The variety is homogamous and begins fruiting in the seventh year. It is characterized by a high yield of up to 40 c/ha, and resistance to drought and heat. It is suitable for industrial cultivation and mechanical harvesting, with fruit shaking efficiency reaching 95%.

Graft survival rates, particularly with summer budding in the open field, may show significant variability.
