The variety was maturi- ty，high quality，high yield，excellent properties such as resistance to diseases and pests. In 2015 it was through the National and Hebei crop variety approval committee authorized. The variety adapted for planting in the Yellow River region in late spring or the region of double cropping of wheat （greens）and cotton.
