It was granted national registration for non-staple crops in April 2024. This cultivar exhibits vigorous growth and rapid development，allowing for sequential harvest approximately 20 days after summer sowing. It boasts excellent marketability and eating quality. The plant has a semi-erect habit，reaching about 30 cm in height. Its leaves are long-obovate with broad-rounded apexes，non-wavy margins，yellow-green color，a flat surface，and a soft texture；the petioles are white and flat. The variety demonstrates strong heat and humidity tolerance，but is susceptible to bolting. It shows high resistance to downy mildew and viral disease，with overall strong disease resistance and wide adaptability.
