Based on this material, a high-yielding variety of 2-row winter bare-grain barley Emperor has been created, which combines ultra-high drought tolerance with high resistance to lodging of plants and a mass of 1000 grains. Marker systems have been selected and optimized for the identification of bare-grain barley samples that are carriers of lpa-1 and lpa-2 mutations and cause a low content of organic and an increased content of mineral phosphorus, which can be absorbed by the human body. The developed methods for identifying mutations that affect the phytate content in the grain of naked barley allow for the effective analysis of barley breeding lines and the selection of mutant samples that can be used in crossbreeding schemes. Seed generations of genetically modified winter wheat plants of breeding-value genotypes with a heterologous gene of alfalfa ornithine-δ-aminotransferase, created by Agrobacterium-mediated transformation by the in planta method, were obtained. In the seed generations of genetically modified wheat, an increase in the level of resistance to water deficit was established due to the introduction of an additional copy of the gene. As a result of a significant improvement in the radiation state of radionuclide-contaminated territories in the immediate vicinity of the Chernobyl NPP, 38 years after the accident, there is a tendency to reduce the intensity of the mutation process, but its level remains dangerous, as evidenced by the 2.7–5.1-fold excess of the spontaneous level of chromosomal aberrations in wheat. Selection samples of winter soft wheat of the Lutescens variety have been isolated, which in the conditions of the northern zones of the Forest-Steppe and Steppe stably maintain ecological plasticity.
