Evaluation of Chloride Accumulation in Soybean Salt-tolerant Mutant Lines Induced by Gamma-ray Irradiation

Land reclamation, inefficient fertilizing practices, and rising sea levels due to climate change and global warming cause salinity stress on crops. Soybean is susceptible to salt stress that significantly reduces plant growth, seed quality and yield. Mutant breeding techniques are useful for improving many agricultural traits by inducing new variations. Gamma ray was used in many crops such as rice, soybeans, and sweet potatoes as mutation breeding techniques. The purpose of this study was to evaluate the chloride accumulation in soybean salt-tolerant mutant lines induced by gamma irradiation to select high salt-tolerant line.
