China is the third largest country in the world in terms of the area of saline and alkaline land,more than 90％of which is inland saline-alkali land,and about 10 million hectares of saline-alkali land can be planted with the saline-alkali tolerant rice.Therefore,it is very important to strengthen the research and development of saline-alkali tolerant rice to ensure the food security of China.This paper systematically introduced the classification of saline-alkali land in China,the characteristics of saline-alkali stress damage of rice,the evaluation and innovative utilization of saline-alkaline tolerant rice germplasm resources,the breeding of saline-alkali tolerant rice varieties,the cultivation management of saline-alkali tolerant rice,the soil restoration of saline-alkali land and the mechanism of saline-alkali tolerant rice.The development strategy of saline-alkali tolerant rice was put forward,that is,through the innovation of saline-alkali tolerant rice germplasm resources,developing rice varieties with stronger saline-alkali tolerance by way of the heterosis utilization and molecular technology,and integrating saline-alkali land soil improvement and high-yielding rice cultivation technology to build a"second granary"in China's saline-alkali land planting area for the strategic needs of national food security.
