Abstract: Guangyou 151, derived from the three-line male sterile line Guangkang 13A with high rice-blast resistance and the restorer line Jianghui 151, was a new three-line hybrid rice variety developed by Sanming Academy of Agricultural Sciences. This variety had the characteristics of high yield, moderate rice-blast resistance, and high rice grain amylose content (27.8%), which was suitable for the processing of rice flour. It was registered and released for the commercial production by Fujian Crop Variety Approval Committee in 2022, with the approval number:Min Approved Rice 20220062. In this paper, the selection and breeding process, main characteristics, yield performance, and processing characteristics of Guangyou 151 were introduced, and the key points of cultivation and seed production technology were put forward, thus to provide theoretical basis for the further production, processing, popularization and application of this variety.
