Abstract Q Liangyou 851 is a two-line hybrid indica rice combination developed using the self bred sterile line Quan151S and the self bred high-quality restoring line YR851. It was approved in the middle and lower reaches of the Yangtze River and the upper reaches of the Yangtze River in 2019 and 2020， respectively. This article analyzed the characteristics of the parents of this combination， as well as the breeding process of the sterile line. Through the practice of cultivation and seed production in recent years， the high-yield and safe seed production technology of this combination had been summarized.
