The hybrid belongs to the linoleic type and is intended for cultivation using Clearfield Plus technology. The plant is medium-tall, with a height of 153–159 cm, a head diameter of about 17 cm, and the thousand kernel weight reaching an average of 73 g.
The variety is distinguished by good drought tolerance and lodging resistance. Tolerance to major diseases, including downy mildew, and resistance to broomrape races A–G are claimed. The production is characterized by a high oil yield.
The hybrid is suitable for intensive and conventional cultivation technologies. The short growing season allows it to be used for late sowing and before winter wheat. The recommended planting density is 45–55 thousand plants per hectare depending on the moisture level of the zone.
