Variety description

10 August 2026

The variety belongs to the early-maturing or mid-early group, intended for a short growing season. Morphologically, the bolls are of medium size and conical in shape with blunt tips. Due to specific growth and development indicators, the variety was used for a long time as a control sample when evaluating new breeding lines.

The plant possesses moderate resistance to Fusarium wilt, while resistance to Verticillium wilt is assessed as low or moderate. In scientific literature, the variety is often mentioned as an object for studying water exchange, photosynthesis processes, and the effects of nematodes.
