Variety description

10 August 2026

The variety is a foreign breeding material that was previously registered in the variety lists of a number of countries. Currently, it has been excluded from the current registers of breeding achievements used in commercial agricultural production.

In scientific literature, the variety is mentioned primarily as an object for testing. Publications provide data on the study of alfalfa pathogens, such as Fusarium wilt, as well as studies on the variety's response to the alfalfa weevil, potato leafhopper, and the effect of herbicides, in particular atrazine.
