“…The Department of Plant Genetic Improvement of the Institute of Plant Physiology and Genetics (IFRG) of the NAS of Ukraine conducts focused breeding aimed at high productivity in combination with high baking quality and a range of other economically valuable characteristics (Morgun et al, 2014). Kozub et al (2018) examined 20 varieties of bread winter wheat from competitive testing for reserve protein loci. Particular attention was paid to new varieties Syntetyk and Bohdanka with rye material, which were also studied using cytogenetic analysis.…”

“…The alleles of the Lr34 gene were evaluated by the codominance of the molecular SNS marker csL V34 by the polymerase chain reaction method. 238 samples that carry the brown rust resistance gene Lr34 in the dominant allelic condition were identified (Kovalyshy-na & Dmytrenko, 2017;Kovalyshyna, 2018). Scientists from the National University of Life and Environmental Sciences of Ukraine, the Institute of Plant Protection of the NAAS of Ukraine and the V. M. Remeslo Mironivka Institute of Wheat identified the allelic condition of the Lr34 gene among the 15 studied varieties Kovalyshyna, 2018).…”

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.

Background: The allelic composition of the gene Lr34/Yr18/Sr57/Pm38/Bdv1, which is associated with resistance to leaf rust in varieties of bread wheat (Triticum aestivum L.), has been investigated. Methods: Three DNA markers were used to determine the allelic state of the gene Lr34/Yr18/Sr57/Pm38/Bdv1: the co-dominant molecular genetic markers cssfr5 and csLV34 and the microsatellite marker Xgwm295. Results: Among 32 cultivars evaluated for resistance to leaf rust, 4 were highly resistant, 26 were resistant and 2 were moderately susceptible. Using the co-dominant marker cssfr5 based on the detection of the polymorphic state of one of the exons of the gene Lr34/Yr18/Sr57/Pm38/Bdv1, the Lr34(+) allele, which confers resistance to leaf rust, was found in 25% of the studied varieties. The coincidence between the results obtained with the markers cssfr5 and csLV34 was 84.5%. Conclusion: The data of the conducted molecular genetic analysis were supplemented by observations of the resistance of the studied varieties to leaf rust in the field. The obtained data can be used in breeding programs to develop new varieties and breeding lines with leaf rust resistance.
