Seedling emerges light pale green with grainy appearance and darker green leaf tip, border, and midrib; greens promptly. v21 of MNL 11:7, indicating allelism with v16, is coincidental - current v21 was named independently and is not allelic to v16. Grainy virescent, greening from tips and margins inward. Genetic 2005 8 coordinates determined from these recombination and map data: TB-8Lb v21; TB-8La v21; (v21 umc1268~psy2); see MaizeGDB ID:301253; 301249; 882299. This gene was originally curated in MaizeGDB Database and the map position was displayed on the maize bins map if feasible.
