Online published on 18 April, 2020. Abstract Mustard brassica is a nutrient-rich plant and can be used to cure many illnesses, especially its seeds have the application of biodiesel production in the future. The significant changes in climate regarding drought and saline soils have a big effect on crop productivity. In this experiment, we want to examine MeSA mutagen with concentrations (0.1, 0.5, and 1mM) on mustard brassica under salt stress with concentrations of NaCl (50; 100; and 150 mM). After several observations, we recognized that MeSA reduced the germination rate while increases the plant's tolerance to saline which was shown in proline content and physiological-biochemical parameters (length of sprouts, chlorophyll content, and carotenoids). Especially at a concentration of 1mM, mustard brassica had a relatively high tolerance. The results of this project will provide useful information for the breeders in creating a new genotype for selective breeding of plants.
