Variety description

10 August 2026

The variety belongs to winter forms and is characterized by the presence of the Rht8 dwarfing gene. In bread-making tests, it demonstrated stable results, however, at high yield levels, it required additional nitrogen nutrition to maintain protein content.

In scientific programs, the variety is known as one of the eight "elite" founders of the MAGIC population. The variety was also used in experimental studies to investigate resistance to drought, ergot, and rust.
