The hybrid was used in field experiments to study the crop's response to nitrogen fertilizers and to create yield models such as DSSAT/OILCROP-SUN. In these models, specific genetic coefficients determining oil content were established for the plant.
This hybrid belonged to the oilseed-type utilization category. At present, the variety is considered obsolete and has been removed from official registries, and available information is limited to parameters for computer modeling without a detailed description of agronomic characteristics.
