Hexiangyou 1 is a new japonica hybrid combination, developed by Jiaxing Academy of Agricultural Sciences and Zhejiang Wuwangnong Seed Industry Co., Ltd. with Hexiang 1A and TD47. The combination has the advantages of good quality, strong comprehensive resistance and wide adaptability. It was released with the authorization of the National Crop Variety Approval Committee of China in 2020, suitable for single season late rice planting in the japonica rice regions of Zhejiang, Shanghai, southern Jiangsu, Anhui and Hubei along the Yangzhi River. According to the field demonstration performance and seed production practice of this variety in recent years, we summarized the high yield seed production technology and direct seeding technology of this combination.
