Variety description

10 August 2026

The variety is widely used in breeding as a parental line for the development of transgenic plants, as well as for studying resistance to abiotic stresses and conducting genetic experiments. In scientific literature, it appears more frequently as a control genotype rather than as a variety for commercial cultivation.

Specialized agronomic descriptions and data on fiber commercial quality in open sources are absent. Studies provide only results of comparative analysis of biochemical indicators, such as the content of tannins and anthocyanins in leaves.
