Abstract:

Evaluation, selection, and utilization of salt-tolerant germplasm resources of cultivated soybean are very important to the exploitation of saline soil. In this paper, recent researches about salt tolerance in cultivated soybean such as evaluation methodology of salt tolerance, physiological and biochemical mechanisms, molecular biology in plant salt tolerance, and selection and exploitation in salt-tolerant germplasm resources are summarized. The problems in current researches are also analyzed. The further research should be based on increasing salt concentration and salt types, with the use of advanced biological technology and testing methods. The appraisal should be carried out comprehensive and systematic with the discovery and application of new germplasm, in order to achieve the innovative use of salt-tolerant germplasm resources of cultivated soybean.
