Abstract

Saline-alkali soil hinders the growth and development of rice at different stages, resulting in the decrease of rice yield. Salt-tolerant rice breeding is an effective way to increase rice yield. In this paper, the effects of salt stress on agronomic traits at different rice developmental stages were reviewed, and the recent research progress in molecular mechanism of salt tolerance in rice was summarized from four aspects: osmotic regulation, ion response, hormone regulation and active oxygen scavenging. Finally, the breeding status of salt-tolerance rice was summarized, and breeding prospects and promotion of new salt-tolerant rice varieties were discussed.
