Variety description

10 August 2026

The Helen BT variety is a genetically modified plant created for agricultural cultivation. Its main feature is the presence of the MON 810 line, which provides the crop with resistance to infestation by certain types of pests, in particular the European corn borer.

Detailed agronomic characteristics of the plant, such as height or maturity, are absent from open sources. The variety is primarily used for scientific purposes as an object for laboratory analyses of transgene stability and for studying physiological indicators of plants under various growing conditions.
