The line has a vegetation period of approximately 111 days and is adapted for cultivation in various regions of the U.S. Corn Belt. It is characterized by high yield potential, stalk strength, good ear productivity, and the ability of the leaves to maintain a green color for a long period.
In breeding work, this line is valued for its high indices of pollen yield and grain test weight. As part of hybrid combinations, the line demonstrates improved moisture release, grain density, and resistance to stalk lodging compared to control samples.
