Variety description

10 August 2026

The hybrid is used in agricultural production; in particular, it is considered as a resource for the fodder base in poultry farming and an object for studying the influence of weeds on crop productivity.

Research on the variety focuses on the analysis of the biochemical composition of the grain, including the content of protein, fat, ash, starch, and moisture, as well as the assessment of morphometric parameters, such as the length, width, and thickness of the seeds.

Detailed agronomic characteristics of the plant, such as height, maturity group, or disease resistance, are not described in available publications.
