Abstract: The floret are the reproductive organs of rice and the basis of grain formation, and their normal development directly affects the yield and quality of rice. Therefore, it is of great significance to study the molecular regulation mechanism of rice floret development for the basic theoretical research of rice development and agricultural breeding. The research results in recent years have shown that jasmonates, auxin and epigenetics have important regulating effect in rice floret development. In this paper, the recent research progress in the regulation of jasmonates, auxin and epigenetics on the production of rice floret and their morphogenesis were reviewed, and it was suggested that more related genes should be isolated in further studies, thus to enrich the regulatory network of rice floret development and promote the analysis of their molecular mechanisms.
