The invention specifically provides a method for continuously reproducing seeds by using a ratooned F1 generation. The method comprises the steps of A. selecting parents to prepare hybrid F1 generation seeds, selecting an F1 combination, performing comparative test and resistance and insect resistance authentication on the F1 generation hybrid seeds, enabling the F1 generation hybrid seeds to participate in various regional tests and get through authorization so as to obtain legality for popularization and utilization in a certain district or area; B. planting the F1 generation hybrid seeds of cotton for ratooning; C. performing experiment and demonstration on F2 generation hybrid seeds harvested in the same year in a cotton region; and D. harvesting F2 generation hybrid seeds in the second to fifth years. According to the method, the using amount of the F1 generation hybrid seeds can be saved; once the seeds are sowed in one year, years of continuous harvesting can be realized, and the quality of reproduced
