“…Prevalence of winter wheat with pathogens is a significant negative factor that reduces the quantitative and qualitative characteristics of the obtained grain harvest (Leonov et al, 2016). The main way to solve the problem of reducing the harmfulness of disease is the creation and introduction of resistant varieties.…”

“…Over the years, scientists from Ukraine, countries from the CIS and non-CIS have conducted a number of studies in this field and obtained significant results as for the identification of resistance genes to brown rust, powdery mildew, septoria, pyrenophorosis (Leonov et al, 2016). In practical terms, winter wheat lines were created using distant and intraspecific hybridization, which had value as a base line for creating resistant varieties.…”

To realize the genetic potential of the productivity of bread winter wheat varieties, it is necessary to maintain a certain level of plant resistance to disease. Resistance donors may lose this property as a result of changes in the virulence of the pathogen and defeat of the genetic systems of plant resistance. This makes it necessary to search for new resistance sources and donors to leaf diseases. Our researches were conducted using field, laboratory and mathematical-statistical methods. Phenological observations, accounting, evaluation and harvesting were conducted according to currently accepted methods. 86 bread winter wheat samples from the 4th WWSRRN CIMMYT were studied for resistance to leaf diseases in our research during 2014–2016. The manifestation of variability depended significantly on the genotype for three diseases. The highest genotype influence was obseved in resistance to septoria disease, where it was 81%. On average the highest indicator of resistance (7.7) to powdery mildew during the three years of research was observed in the mid-late ripening samples. The mid-early ripening group was considered to be the most adapted to the powdery mildew pathogen in the Northeastern Forest-Steppe. The highest average indicator of resistance (7.5) to brown rust for the three years of research was found in the early ripening group. The samples of the mid-ripening group were most adapted to the brown rust pathogen. The highest average resistance to septoria disease was also found in the early ripening group. The best adaptation to septoria disease was observed in mid-late ripening samples. 36% of the samples were resistant to three diseases. As a result of the research, a number of CIMMYT samples were isolated from the 4th WWSRRN, which exceeded the standard in resistance to powdery mildew, brown rust and septoria disease. They were characterized by better performance. Valuable forms for breeding work that can be resistance donors to leaf diseases were identified among them.

Purpose. Based on the study of oxidative and antioxidant processes in wheat plants (Triticum aestivum L.) in the earing phase at the infection by Septoria tritici Rob., identify the varietal features of changes in the level of hydrogen peroxide, the intensity of lipid peroxidation and the activity of antioxidant enzymes for development of biochemical methods for selection of disease-resistant plants. Methods. Field, spectrophotometric methods of biochemical characteristic determination, comparison, generalization. Statistical analysis of research results was carried out using the program Libre Office Calc (GNU Lesser General Public Licensev3). Results. Changes in the content of hydrogen peroxide, malondialdehyde and the activity of catalase, superoxide dismutase, peroxidase in wheat plants infected by S. tritici at the earing phase were determined. The presence of varietal features of changes in the oxidative and antioxidant processes of wheat plant cells upon S. tritici infection were detected. It was shown that plant response to S. tritici damage in more disease-resistant wheat varieties were characterized by increased or unchanged relative to the control the content of malondialdehyde and peroxidase activity. Conclusions. The obtained results will expand the knowledge about the mechanisms of maintaining ROS homeostasis in wheat plants infected by S. tritici and allow to identify biochemical reactions of wheat plants in response to infection, which can be used in the future for the development of biochemical methods for identification of disease-resistant varieties.
