Variety description

10 August 2026

The variety possesses high grain yield, exceeding that of standard varieties. It is distinguished by an increased thousand kernel weight and a high hectoliter weight of the grain.

The plant responds well to the application of growth regulators, which contributes to an increase in yield. The variety is actively used as a subject of research when evaluating the effect of agronomic practices, including the application of fertilizers and the use of herbicides, on the productivity of durum wheat.
