The introduction of the genetic material of wild-growing species into the genome of cultivated plants can signifi cantly expand the diversity of breeding material. For the eff ective use of introgressive plants, it is necessary to study their economically valuable traits and adaptive capabilities. The objective of the work is to study the eff ect of two types of salinity on the morphogenesis of seedlings of introgressive lines of spring bread wheat containing the genetic material of Aegilops columnaris Zhuk.
