Get saline-tolerant soybean seeds can be produced using soybean mutant seeds that are induced by chemical or physical mutations. This study used soybean mutant that has previously been chemically induced by colchicine which is expected to produce plants that able to adapt to saline soils. This field experiment was conducted on January-March 2020 in Faculty of Agriculture, Universitas Sumatera Utara. The experiment was arranged in a Randomized Block Design with one treatment that are levels of salinity (0; 2; 4; 6 dS/m) with ten replicates for each treatment. The data were analyzed statistically using ANOVA and then following by the DMRT test at 5% level. The results of this study show that increasing salinity can decrease phenotypic characters, were root length, root volume, root dry weight, canopy dry weight, and length of stomata. However, we discovered that soybean mutant can well grow at S3 (4 dS/m) as following the parameters were plants height (21.77cm), stem diameter (2.90cm), amount of stomata (42.67 stomata), and width of stomata (15.76 µm). Moreover, we discovered that the chlorophyll content of the soybean mutant increases until at 4 dS/m (7.67 g/ml).
