Variety description

10 August 2026

The variety belongs to the winter crop type. In agronomic research, it served as an important breeding resource, from which other oat varieties were developed. In scientific studies, the variety was used as a model object for performing genetic transformations via particle bombardment.

In field trials, the variety was examined in the context of its response to nitrogen fertilizer application and the use of plant growth regulators to control stem height and increase lodging resistance. Analyses of grain quality indicators, such as oil content and the kernel-to-hull ratio, were also conducted. In comparative trials, the variety's susceptibility to powdery mildew and crown rust was noted.
