The variety is an inbred line developed by crossing parent forms PH1M77 and PH25Y2. The plant is characterized by late flowering, a wide leaf blade above the top ear, and an elongated ear compared to the control variety PH1M77.
The stalk of the line has almost no zig-zagging, and the brace roots have weak anthocyanin coloration. The tassel is distinguished by a moderate number of lateral branches and a very short axis above the top branch. The line is intended for use in breeding programs for creating new hybrids.
