sulfate salinity

The study of the resistance of plants obtained as a result of introgressive breeding to the action of various factors, including salinization, is an important stage of breeding work. The eff ect of salt stress on the growth and development of the root system of seedlings of introgressive lines of spring soft wheat has been studied. The objects of the study are seedlings of introgressive lines of spring soft wheat obtained with the participation of Triticum dicoccum Shuebl, Aegilops speltoides Tausch, Agropyron elongatum (Host) Beauv.

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.
