The invention relates to a photoperiodic tolerant mutant hd1-3 gene for regulating and controlling the flowering time of rice. The nucleotide sequence of the gene is SEQ ID No.1, and the corresponding hd1-3mRNA sequence of gene is SEQ ID No.2. The invention discovers a photoperiodic tolerant mutant in a constructed rice insertion mutant pool. The mutant provides an extremely good base material for researching the flowering mechanisms of short day plants under the photoperiodic conditions; by the research of the invention, an important functional gene which has specific functions and is used for regulating and controlling the flowering time of the rice is expected to be obtained, which not only provides evidences and the base material for proving the flowering mechanisms of the short day plants under the photoperiodic conditions but also has important practical significance and economic benefit for guiding the breeding of the rice (particularly the breeding of two-series hybrid rice), regulating the growth period of the rice, further improving the yield of the rice and solving the grain problems of the world population. The relevant research provides the theoretical basis for the molecular design of the breeding of the rice and provides references for the production development and the theoretical research of other crops.
