Abstract: Edamame variety with the characteristics of SMV resistance and early maturity was developed to meet the key technology demand of the edamame industry of Jiangsu Province. The new edamame variety Suzao 2 was identified from the cross of Chunfengzao and Liaoxian 1, and which was identified through many years and multi-locations of the traits selection. Through the identification of soybean variety regional tests in Jiangsu Province, it was found that this variety had the characteristics of early maturity, resistance to SMV SC3 and SC7 strains, high yield and good edible taste. The new soybean variety Suzao 2 was certificated by Jiangsu Provincial Soybean Variety Approval Committee in July 2020, and could be used for spring sowing in Jiangsu Province. This paper summarized the breeding process, characteristics and cultivation technology of Suzao 2.
