In order to screen out the saline-alkali-tolerant rice germplasm resources suitable for planting in Hinggan League area of Inner Mongolia, we comprehensively evaluated the saline-alkali tolerance of 102 rice germplasm resources promoted and introduced in Inner Mongolia by analyzing the percentage of dead leaves, aline-alkali hazard index, yield traits and agronomic traits. The results showed that Changbai 9, Suigeng 26, Wulan 105, Jinongda 538, Songliao 5 and Songliao 186 performed high saline-alkali tolerance and yielding ability, which could be used as saline-alkali resistant resources.
Key words： rice; saline-alkali tolerance; germplasm resources; screening
