Variety description

10 August 2026

The hybrid belongs to the early-maturing group with a vegetation period of 100–110 days and has a below-average plant height. The seeds are characterized by high oil content at the level of 50–55% and an oleic acid content of more than 90%.

The plant possesses genetic resistance to broomrape races A–G and System II, as well as to common races of downy mildew. Tolerance to phoma, phomopsis, verticillium wilt, and white rot is noted. The hybrid is resistant to tribenuron-methyl-based herbicides, which allows for the use of ExpressSun technology for weed control.
