The object is classified not as an independent commercial hybrid for field cultivation, but as an initial inbred line. It is used in breeding to produce hybrids, rather than for mass cultivation for grain or silage.
The morphological and economic traits of the line, including disease resistance and yield indicators, are proprietary breeding information. These parameters are evaluated by the developers exclusively to determine combining ability during crossing in the course of breeding work.
