This line is not intended for commercial production and acts as a male component in breeding work. Specialized characteristics, such as yield, height, or maturity group, are absent in public disclosures.
Studies indicate weak competitive ability of the line against weeds and sensitivity to the application of herbicides at early stages of development. The effect of herbicides is manifested by slowed growth and necrosis of primary leaves.
