Variety description

10 August 2026

The variety is an object of scientific research and breeding work, intended for cultivation on lands unsuitable for food crops. In a five-year rotation system, the plants reach an average height of 7.3 m, showing a fresh wood yield of about 18 t/ha per year.

The wood is characterized by low moisture, reduced content of ash, nitrogen, sulfur and chlorine, as well as a high calorific value. The variety is often mentioned in works dedicated to the application of laser radiation to stimulate the growth of cuttings and increase biomass volume.
