Variety description

10 August 2026

The variety is specialized as a nematode-resistant catch crop, the main purpose of which is to suppress the population of sugar beet nematode in crop rotations with sugar beet. The variety is also used for improving soil structure, weed suppression, erosion protection, and nitrogen conservation.

Possesses high resistance to sugar beet nematode, corresponding to resistance level 2, which ensures a population reduction of up to 90%. Characterized by rapid initial growth and late onset of flowering, which allows for an extended vegetative growth period for nematode control.

Root system type is fasciculate with a distinct taproot penetrating to a depth of up to 120 cm, which contributes to improving the soil's water-air balance. The variety is characterized by lodging resistance at the level of 3 points.
