The line possesses a yield higher than average compared to the PHP38 line and is characterized by late flowering dates, determined by GDU indicators for anthesis and silking. Morphologically, the line is distinguished by a predominantly pink silk color.
In scientific research, the line is considered in the context of studying resistance to northern corn leaf blight, particularly when investigating the Ht1 resistance gene. The line is used as a component in crosses for breeding work, including its use as a recurrent parent.
