Variety description

10 August 2026

The variety is archival and is not used in modern commercial production. In the mid-20th century, it was frequently used in European and North American studies, where it served as a reference variety for comparison with other rye varieties, such as Petkus.

Scientific papers of that period noted the variability of the variety regarding the number of leaves on the main stem, ranging from 11 to 14. This indicator correlated with the plant's development rate, internode length, and the number of spikelets per ear. Features of the leaf development rhythm, ear formation, and resistance to pre-harvest sprouting were also studied.
