Variety description

10 August 2026

The variety belongs to the feed-use direction. The plant is short-stemmed, and the tillering type at the early stages of development is intermediate. Due to the strong stem, the variety has good lodging resistance.

Overall disease resistance is characterized as good, however, susceptibility to yellow rust is noted. In scientific literature, the variety is considered in the context of identifying powdery mildew resistance genes, and is also used as an object for analyzing nitrogen use efficiency.
