Variety description

10 August 2026

The variety is mentioned in a number of scientific papers devoted to the study of the influence of agrotechnical factors — sowing dates, nitrogen fertilization, and irrigation — on growth dynamics, the accumulation of organic matter in the root system, and spring plant regeneration.

Separate studies using this variety touched upon issues of seed production, in particular the effect of row spacing on seed yield indicators. A detailed morphological description of the variety or official data on disease resistance are absent in available publications.
