| Abstract: | The storability of rice seeds is an important trait related to grain storage safety and the safety of seed use, it is also the focus in seed research and by seed enterprises. Rice seeds with strong storability still exhibit high seed vigor after long-term storage, these rice varieties can be better used to solve the problem of grain storage and the safety of seed use. In this review, we introduced the reasons of seed aging and deterioration, discussed the physiological and biochemical mechanisms of seed during storage, summarized the research progresses of genetic mechanism of rice seed storability. Finally, we made an outlook for how to breed the new variety of rice with strong storability. |
