A rice mutation pool has been developed with over 6000 new stains, including japonica and indica strains mutated by chemical mutagen NaN₃. The pool facilitates many types of mutagenesis, including agronomic traits (e.g., leaf color, plant height, and seed coat color), physicochemical traits (e.g., fragrance, starch, protein, and composition), and antistress (e.g., bacterial blast, blast, brown planthopper, white back planthopper, salt, drought, and cold). The pool can be used to screen for new characteristics to increase the value of the rice industry and functional gene research.
