The line was developed based on genetic material from NPH8540 and 911. It is not a commercial hybrid for mass cultivation, but serves as a specialized breeding resource.
In scientific and regulatory documentation, it is used as genetic material for comparative studies in the analysis of various maize modification events. During the line development, selection was conducted based on the indicators of flowering synchrony of male and female inflorescences, plant health, ear fill, and resistance to stalk rots.
