Abstract: In order to study the flowering adjustment technology on parents of the water-saving and drought resistant hybrid rice, with three CMS lines and two restorer lines as materials, the experiment was carried under the early stage of differentiation of rice panicle with 4 flowering adjustment substance: Urea(N), Paclobutrazol (MET), MCPA, and Potassium dihydrogen phosphate (K). To explore the flowering adjustment technology and provide beneficial help for water-saving drought resistant hybrid rice seed production.

Key words: hybrid rice, water-saving and drought resistant, flowering adjustment
