Most crop plants including wild soybeans are sensitive to salt stress.
Sources of salt tolerance have been identified among some related wild species. These genetic resources could potentially be used to improve salt tolerance of soybean cultivars. In previous study, we employed isozymes and RAPDs as genetic markers to identify the relationship between the markers and salt-tolerance. Amplification was performed in an Idaho Technology thermal cycler. But whether the polymorphisms and salt-tolerance are inevitably related demands further study and discussion.
