Variety description

10 August 2026

The hybrid belongs to the mid-early maturity group and has an average plant height of about 159 cm, reaching up to 179.9 cm under certain conditions. The plant head averages 18 cm in diameter. The 1000 kernel weight ranges from 60 to 70 g; the hybrid is distinguished by high oil content and high lodging resistance.

The plant possesses high tolerance to brown rust, downy mildew, Phomopsis, root white rot, and dry rot. The hybrid is resistant to Orobanche races A–F and demonstrates high drought tolerance and good cold hardiness during initial growth stages.

The hybrid is intended for classical intensive cultivation technology. Thanks to its vigorous leaf apparatus and high initial growth vigor, it effectively suppresses weed development and contributes to soil moisture retention. Recommended for the Forest-Steppe and Northern Steppe zones.
