Variety description

10 August 2026

The variety belongs to the spring type. In scientific publications, the original variety is described as susceptible to powdery mildew, which is why it has often been used in breeding experiments to study the transfer of resistance genes from wild oat species.

In the academic community, the variety is widely used in biotechnology: immature embryos are used for callus initiation and plant regeneration by in vitro tissue culture methods. It has been noted that genetic manipulations aimed at increasing resistance led to a decrease in the yield of the variety.
