The AM 4 A line is used as a maternal form in hybridization plots to produce sunflower hybrids, specifically such as «Беркана» and «Беркана нова». The plant possesses resistance to the action of CLEARFIELD technology herbicides.
During hybridization, the line demonstrates high yield. The seeds of the maternal form AM 4 A are larger than the seeds of the paternal form АМ Л1 В, which requires special adjustment of sowing equipment and selection of appropriate sowing discs.
