The article presents the results of seed germination of some varieties of grain sorghum from the Povolzhsky NIISS FGBNU in conditions of various salinization. The degree of resistance of the investigated varieties to sulfate, chloride and mixed types of salinity is established. The influence of different salinity on the length of the roots was revealed.
