“…Isolates from common wheat had a greater number of virulence alleles compared to those from durum wheat. No common phenotypes were found on durum and soft wheat (Shaydayuk et al, 2019;Shaydayuk, 2020). The virulence phenotypes of common wheat differed from those of durum wheat in all study areas, which indicates a difference in the composition of pathogen populations of T. durum and T. aestivum.…”

“…The North Caucasian samples of populations from winter cultivars of durum wheat had significantly lower frequencies of virulence on TcLr17 than the Volga, Ural, and West Siberian samples, and higher virulence on TcLr44. The frequencies of virulence on TcLr20, TcLr23 and TcLr26 spontaneously varied in all studied populations (Shaydayuk, 2020). Russian isolates of P. triticina from durum wheat in 2017-2019 differed in virulence from isolates from other countries, which may be due to differences in the cultivated composition of T. durum genotypes in different countries (Martinez et al, 2005;Ordoñez et al, 2007;Mantovani et al, 2010;Goyeau et al, 2012).…”

“…Because of this, the final loss of the effectiveness of this gene in these regions became obvious by the middle of 2010 (Meshkova and Roseeva, 2016). In the modern period, virulence on the Lr9 gene dominates in the Asian regions of the Russian Federation, where cultivars protected by this gene are widely grown (Gultyaeva et al, 2020). Since mid-2010, similar phenotypes have also been found in European regions (Central Black Earth Region and the Volga region), where winter cultivars with this gene now also grow.…”

“…In 2017-2019, the All-Russian Institute of Plant Protection continued studies on populations of durum wheat (Shaydayuk et al, 2019;Shaydayuk, 2020). Geographically distant populations of P. triticina -North Caucasian (including samples from Dagestan, Krasnodar Krai and Rostov Oblast), Volga (Samara Oblast and Chuvashia), Ural (Chelyabinsk Oblast) and West Siberian (Altai Territory and Omsk Oblast) populations were studied.…”

The article analyzes our own data and data from the literature on the study of plant–pathogen interactions in the pathosystem of Puccinia triticina and host plants of the genera Triticum and Aegilops with different ploidy and genomes. We characterize the long-term variability of the Russian populations of the pathogen, caused by the cultivation of genetically protected cultivars of common wheat (T. aestivum). Differences of the pathogen’s virulence on hexaploid species T. aestivum and tetraploid wheat (T. durum) are shown. Data on the pathogen’s virulence on other hexaploid, tetraploid, and diploid relative species Triticum sp. and Aegilops sp. are presented. Adaptation and specificity to the host plant were shown as the key driving factors in the evolution and divergence of clonally propagating phytopathogens, which include leaf rust.

“…Previous studies have reported variations in Ptr populations in Kazakhstan [ 4 , 27 , 30 ]. It is therefore necessary to periodically evaluate resistant cultivars and advanced breeding lines against Ptr races in order to monitor resistance breakdown and plan the replacement of susceptible cultivars with resistant cultivars.…”

Leaf rust, caused by Puccinia triticina (Ptr), is a significant disease of spring wheat spread in Kazakhstan. The development of resistant cultivars importantly requires the effective use of leaf rust resistance genes. This study aims to: (i) determine variation in Ptr population using races from the East Kazakhstan, Akmola, and Almaty regions of Kazakhstan; (ii) examine resistance during seedling and adult plant stages; and (iii) identify the sources of Lr resistance genes among the spring wheat collection using molecular markers. Analysis of a mixed population of Ptr identified 25 distinct pathotypes. Analysis of these pathotypes using 16 Thatcher lines that are near-isogenic for leaf rust resistance genes (Lr) showed different virulence patterns, ranging from least virulent “CJF/B” and “JCL/G” to highly virulent “TKT/Q”. Most of the pathotypes were avirulent to Lr9, Lr19, Lr24, and Lr25 and virulent to Lr1, Lr2a, Lr3ka, Lr11, and Lr30. The Ptr population in Kazakhstan is diverse, as indicated by the range of virulence observed in five different races analyzed in this study. The number of genotypes showed high levels of seedling resistance to each of the five Ptr races, thus confirming genotypic diversity. Two genotypes, Stepnaya 62 and Omskaya 37, were highly resistant to almost all five tested Ptr pathotypes. Stepnaya 62, Omskaya 37, Avangard, Kazakhstanskaya rannespelaya, and Kazakhstanskaya 25 were identified as the most stable genotypes for seedling resistance. However, most of the varieties from Kazakhstan were susceptible in the seedling stage. Molecular screening of these genotypes showed contrasting differences in the genes frequencies. Among the 30 entries, 22 carried leaf rust resistance gene Lr1, and two had Lr9 and Lr68. Lr10 and Lr28 were found in three and four cultivars, respectively. Lr19 was detected in Omskaya 37. Two single cultivars separately carried Lr26 and Lr34, while Lr37 was not detected in any genotypes within this study. Field evaluation demonstrated that the most frequent Lr1 gene is ineffective. Kazakhstanskaya 19 and Omskaya 37 had the highest number of resistance genes: three and four Lr genes, respectively. Two gene combinations (Lr1, Lr68) were detected in Erythrospermum 35 and Astana. The result obtained may assist breeders in incorporating effective Lr genes into new cultivars and developing cultivars resistant to leaf rust.

Leaf rust (LR) is the most widespread disease of common wheat worldwide. In order to evaluate leaf rust resistance, 70 uncharacterized wheat cultivars and promising lines with unknown leaf rust resistance genes (Lr genes) were exposed to Kazakhstani Puccinia triticina (Pt) races at the seedling stage. Field tests were performed to characterize leaf rust responses at the adult plant growth stage in the 2020–2021 and 2021–2022 cropping seasons. The wheat collection showed phenotypic diversity when tested with two virulent races of Pt. Thirteen wheat genotypes (18.6%) showed high resistance at both seedling and adult plant stages. In most cases, breeding material originating from international nurseries showed higher resistance to LR. Nine Lr genes, viz. Lr9, Lr10, Lr19, Lr26, Lr28, Lr34, Lr37, Lr46, and Lr68, either singly or in combination, were identified in 47 genotypes. Known Lr genes were not detected in the remaining 23 genotypes. The most commonly identified resistance genes were Lr37 (17 cultivars), Lr34 (16 cultivars), and Lr46 (10 cultivars), while Lr19, Lr68, Lr26, and Lr28 were the least frequent. Four Lr genes were identified in Keremet and Hisorok, followed by three Lr genes in Aliya, Rasad, Reke, Mataj, Egana and Almaly/Obri. The molecular screening revealed twenty-nine carriers of a single Lr gene, ten carriers of two genes, six carriers of three genes, and two carriers of four genes. Most of these accessions showed a high and moderate level of APR (Adult plant resistance) and may be utilized for the incorporation of Lr genes in well-adapted wheat cultivars. The most effective combination was Lr37, Lr34, and Lr68, the carriers of which were characterized by a low disease susceptibility index. The obtained results will facilitate breeding programs for wheat resistance in Kazakhstan.
