Variety description

10 August 2026

The variety is a loose-bunch perennial grass. It is used for breeding purposes and for studying genotype-by-environment interactions, in particular the influence of photoperiod and temperature regime on shoot development and heading processes.

In scientific experiments using this variety, the rates of leaf elongation, shoot emergence dynamics, and the speed of the plant's transition from the vegetative to the reproductive state are evaluated.
