The variety is registered as a specialized breeding line used for creating hybrids, rather than for commercial grain or silage production. In scientific studies, the line demonstrated high combining ability indices for grain yield in steppe zone conditions.
Detailed morphological characteristics and maturity group data for this line are highly specialized breeding information and are not available in open sources. During the testing process, the line's reaction to different plant densities was studied, including rates of 50,000 and 70,000 plants per hectare.
