This line is not a commercial variety for broad cultivation, but acts as breeding material. The main direction of work using it is the study of stress tolerance mechanisms, in particular, the response of plants to drought.
In scientific research, the line is used to evaluate physiological parameters, such as the characteristics of the root system, stems, and chlorophyll fluorescence under moisture deficit conditions. Data on specific maturity or plant morphology indicators are not published, as they are part of a closed breeding process.
