Variety description

10 August 2026

The variety is a spring-type oat. In agronomic and breeding literature, it is widely known as genetic material for the creation of new varieties; in particular, it was used in hybrid combinations during the development of Tyumen-bred varieties.

In scientific publications, the variety is characterized as a convenient object for biotechnological breeding methods, as it possesses good ability for callus formation in in vitro culture.
