Evaluation for saline-sodic tolerance of nine potato cultivars in pot trial.

Nine potato cultivars gorwn in pots containing saline-sodic soil were evaluated for their saline-sodic tolerance through observing the emergence,survival percentage and yield.The results indicated that these cultivars had different levels of saline-sodic tolerance,and the saline-sodic tolerance was correlated with the emergence rate and yield.The potato cultivar Kexin 19 was the best one with saline-sodic tolerance.
