10 sorghum strains germinated under 0, 0.2%, 0.4%, 0.6%, 0.8% NaCl solution stress, the salt injury was evaluated with the injury of salt to the rate of germination, root length, the number of lateral roots, the duration of 1 / 2 leaf wilting and of the entire leaf wilting. Based on the changes of the above six indicators, the system of each index score for each indicator were developed. The salt tolerance of each sorghum strain was evaluated according to the total scores based on each indicator. A set salt-tolerant evaluation criteria was developed to evaluate salt tolerance. According to the degree of salt tolerance, these strains were divided into four levels. Five materials with different salt-tolerance from the ten sorghum strains were chosen to identify the salt tolerance with planting in saline soils contain 0.5% and 0.7% salt respectively in pots to verify the criteria. The results showed that the evaluation criteria was consistent with the test in pot, which confirmed the evaluation method used in the screening tolerant sorghum are reliable. Two high salt-tolerance sorghum strains, HN-1 and NS-1 were screened with this method.
