Two salt resistant forms of the mustard Brassica junceae were obtained. These forms demonstrated no chlorophyll defects. SR2 and SR3 salt resistant forms have constant parameters of productivity in condition of NaCl salting, in comparison with the initial plants of sort Donskaya-5. Results of a comparative ultrastructural analysis of plastids show that the salt influences the plastid ultrastructure of SR2 and SR3 lines of mustard in a lesser degree in comparison with the sort plants. The plastids of SR2 and SR3 salt resistant lines of mustard are functionally quite active under stress conditions.
