Xinfeng No. 1 was developed by the Agricultural Technology Extension Station of Hongmiaozi Township, Xinbin County, through sexual hybridization and selection using Chang No. 4 as the female parent and Qunxuan No. 1 as the male parent. It was approved by the Crop Variety Approval Committee of Liaoning Province in December 2002. The variety has a growth period of 121 days and belongs to the early-maturing group. The average plant height is 94.7 cm, with a semi-determinate podding habit and 17.9 nodes on the main stem. The stems are thick and tough, the root system is well developed, and it is lodging-resistant. The leaves are round, the pubescence is gray, and the flowers are white.
