“…2-27.6% of the fungal isolates tested. In the previous period of research carried out by Czajowski et al (2011) and by Hanzalová et al (2013;, the pathotypes 12720, 12724 and 12762 appeared more frequently. A common feature of these pathotypes is virulence against the following genes: Lr1, Lr3, Lr11, Lr15, Lr17 and Lr21 (Czajowski et al, 2016).…”

Among all cereals, common wheat (Triticum aestivum L.) occupies the largest area of crops worldwide. Wheat leaf rust, caused by the pathogen Puccinia recondita f. sp. tritici considerably reduces the yield of wheat. Breeding for resistance combined with selection based on molecular markers may become an effective tool in the struggle against fungal diseases. Lr19 is the gene that carries high resistance to wheat leaf rust. In recent years, we have seen the development of many molecular markers in close neighbourhood of the Lr19 gene, e.g., SCS265, SCS253, GB, Xwmc221, XustSSR2001-7DL, Xgwm37 and Xgwm44. The aim of the study was to investigate the functionality of molecular markers related to the Lr19 gene. The study was based on two reference genotypes with the Lr19 gene ('Agatha' and Lr19) and three lines strongly infested by wheat leaf rust. Seven molecular markers were analysed, but only two of them (GB and Xwmc221) proved to be specific to the gene under study. These markers were used for analysis of 25 wheat genotypes, which were evaluated for leaf rust resistance in field conditions to confirm their usefulness for selection of breeding material. These findings point to the need of continuous search for functional molecular markers giving repeatable and reliable results.

“…Neviski (McIntosh et al, 2013). According to the last monitoring, virulence to Lr24 was very rare in Germany, Spain, Hungary, Slovak Republic (HuertaEspino et al, 2011), and Czech Republic (Hanzalova et al, 2013), Lithuania (Liatukas, 2003) and China (Liu and Chen, 2012). In Ukraine, Lr24 exhibited moderate susceptibility at the seedling stage and resistance at adult plant stages.…”

Leaf rust is the most widespread and frequently occurring fungal disease of wheat (Triticum aestivum L.) in Ukraine and worldwide. The information about the effectiveness of Lr-genes and also the consequent monitoring of virulence dynamics is necessary for the successful wheat breeding for leaf rust resistance. In 2013-2014 pathotype composition and virulence analysis was studied both on the standard differential set and on the North American System of Nomenclature. According to the standard differential set, 12 phenotypes were identified, of which the most common were 77 (75%) and 144 (6%). A total of 40 phenotypes were identified on the North American Nomenclature. Phenotypes TGTT (24%) and TJTT (8%) were the most frequent, TRTT (1.5%) and TSTT (1.5%) were within the broadest spectrum of virulence among the isolates found in the south of Ukraine. For virulence analysis we used wheat lines of 'Thatcher' that are near-isogenic for 24 leaf rust resistance genes and additionally four cultivars/lines. No virulence to Lr19 was found, whereas increasing virulence to Lr9 was detected (13%). Low frequency of virulence was observed to Lr29 (11%) and Lr47 (21%), high level of virulence was detected to other genes. The effectiveness of 53 known Lr-genes was studied at the seedling and the adult plant stages. Most of them were not effective against leaf rust. Genes Lr9, Lr19, Lr29, and Lr47 were highly effective both at the seedling stage and at adult plant stage. Genes Lr24, Lr42, Lr50, Lr51, and Lr56 were effective only at the adult plant stage.

According to the experts of the Food and Agriculture Organization (FAO), the annual global loss of products from diseases and pests of agricultural crops in 1986-1990 was 52.2 million from 1998-2005 from a conventional unit of grain to 70 million tons. One of the factors that reduce the yield indicators of grain crops, contributing to a sharp decrease in yield, is the rust disease, which causes damage to grain crops, except for wheat Aegilops, Elymus, Agropyron, etc. The problem of contamination of grain crops with phytopathogenic fungi is quite a serious problem for the countries of Central Asia, since, according to FAO, this region is characterized by a higher level of bread consumption per capita (about 200 kg per year), and agriculture is considered as one of the key factors of the economy. The cost of production is an economic factor and negatively affects the sustainable development of agricultural production. A comprehensive study of the source material obtained in breeding, the replacement of ineffective ones with effective ones, makes it possible to suppress the rate of development of the pathogen and prevent epiphytosis. The evolution of the adapted parasite is accompanied by the evolution of the host plant. The article examines the complex resistance of domestic and foreign wheat varieties to rust in an artificial epidemic environment. Over the years of research, a comparative analysis of the resistance of wheat varieties to diseases has been carried out. Field tolerance was noted in the varieties Almaly, Arap, Zhakut, Naz with 3-4 points, in the varieties Samar and Zhalyn with 2 points. As a result of the structural analysis of the yield of winter wheat varieties allowed for sowing in production and promising, a decrease in these indicators was found under the influence of the disease.
