This invention provides a method for inducing chromosome doubling in rice using ammonia-sulfuron-methyl and its application, belonging to the field of rice breeding technology. In this invention, after culturing callus tissue from rice seeds or embryos, the callus tissue is inoculated into a doubling medium containing 0.005 g / L ammonia-sulfuron-methyl for further culture. Following recovery culture, differentiation culture, and rooting culture, root tips are taken from the plants, and chromosome counting is performed under a microscope. Plants with doubled chromosome numbers are selected as tetraploid rice. Compared to the colchicine-induced chromosome doubling method, this method is more efficient and safer. The successful development of this method provides a new approach for rice breeding and new variety creation.
