Variety description

10 August 2026

The hybrid belongs to the moderately intensive type and shows responsiveness to soil fertility. Plant height varies in the range from 140 to 170 cm depending on moisture availability conditions. The crop is intended for oilseed use.

The plant possesses high resistance to a number of pathogens, including broomrape races A, B, C, D, E. The hybrid is recommended for regions with a high infectious background of Phomopsis and Sclerotinia, provided there are no specific broomrape races present. It is characterized by high tolerance to crop density.
