Variety description

10 August 2026

The variety belongs to the early-maturing category, sometimes classified as medium-early. The tubers have an elongated-oval shape and are colored yellow-brown. A distinctive morphological feature of the variety is a smaller leaf surface area and a lower proportion of leaf mass compared to a number of other varieties.

The main purpose of the variety is food use. In addition, the variety is an object of scientific research in the field of agrotechnics, the efficiency of inulin accumulation, and use as a raw material for bioenergy. In agrotechnical studies, the variety is considered as a model when studying the effect of nitrogen fertilizers and irrigation on crop productivity.
