“…Kolmer et al (2020) showed that geographical proximity has a decisive influence on the relative diversity among a population; this was well documented by study of differentiation among P . triticina populations in the Russian Federation with isolates collected over a broad geographical area in different agroclimatic regions of the European and Asian parts of Russia (Gultyaeva et al, 2020, 2021). The significant differentiation observed among the Russian populations of P .…”

“…Currently, studies of genetic diversity in populations of P . triticina conducted by other researchers are based on isolates collected from common wheat, durum wheat, and wild wheat species (Goyeau et al, 2007; Gultyaeva et al, 2016, 2018, 2020, 2021; Kolmer et al, 2013, 2015; Kosman et al, 2014). Thus, no information is available regarding the variability and structure in European populations of P .…”

“…Initially, random amplification of polymorphic DNA (RAPD) (Park et al, 2000) was used, and recently, simple sequence repeat (SSR) markers have increased in popularity. Studies conducted by Goyeau et al (2007), Kolmer et al (2013, 2015) and Gultyaeva et al (2017, 2021) using SSR markers proved that the European P . triticina population is highly structured and exhibits a significant relationship between virulence and molecular variation.…”

Triticale (×Triticosecale), the first human-made crop species in a hexaploid form (AABBRR), was obtained by crossing tetraploid wheat (Triticum durum or T. turgidum) with cereal rye (Secale cereale or S. montanum) (Ammar et al., 2004). The first commercially available triticale cultivars for farmers became available in the 1960s.Recently, the global cultivated area of triticale has been estimated at approximately 4 million hectares, with the largest areas occurring in Poland, Belarus, Germany, and France. In Poland, triticale is grown on approximately 1.3 million hectares. In general, triticale combines the high grain quality and yield potential of wheat with the resistance to biotic and abiotic stresses of rye (Ammar et al., 2004; Audenaert et al., 2014).Leaf (brown) rust, which is caused by Puccinia triticina, is an important wheat disease in all geographic regions of the world where wheat is cultivated (Bolton et al., 2008). The development of leaf rust is strongly influenced by environmental conditions, among which temperature and moisture play the most significant role (Kaul & Shaner, 1989). In Poland, under favourable disease conditions, a peak of leaf rust development may start in June and last until leaves senesce at the end of July. For many years, triticale was considered

“…In particular, mutations, resulting in new genetic variants, are likely the primary source of variation in P. triticina populations [ 7 ]. In wheat-producing countries, large-scale surveys aimed at monitoring the diversity of virulence phenotypes (races) in P. triticina populations have been performed repeatedly as the control of leaf rust relies mainly on wheat cultivars with race-specific resistance genes [ 4 , 9 , 11 , 12 , 13 , 14 , 15 , 16 ]. The analysis of the genetic variability of P. triticina populations can provide further insight into the biology and ecology of the leaf rust pathogen.…”

“…While RAPDs and AFLPs are dominant, SSR and ISRR markers are co-dominant and can distinguish heterozygous and homozygous genotypes [ 3 , 7 ].

Puccinia triticina is a major wheat pathogen worldwide. Although Iran is within the Fertile Crescent, which is supposed to be the center of origin of both wheat and P. triticina, the knowledge of the genetic variability of local populations of this basidiomycete is limited. We analyzed 12 inter simple sequence repeats (ISSRs) and 18 simple sequence repeats (SSRs) of 175 P. triticina isolates sampled between 2010 and 2017 from wheat and other Poaceae in 14 provinces of Iran. SSRs revealed more polymorphisms than ISSRs, indicating they were more effective in differentiating P. triticina populations. Based on a dissimilarity matrix with a variable mutation rate for SSRs and a Dice coefficient for ISSRs, the isolates were separated into three large groups, each including isolates from diverse geographic origins and hosts. The grouping of SSR genotypes in UPGMA dendrograms was consistent with the grouping inferred from the Bayesian approach. However, isolates with a common origin clustered into separate subgroups within each group. The high proportion of heterozygous alleles suggests that in Iran clonal reproduction prevails over sexual reproduction of the pathogen. A significant correlation was found between SSR and ISSR genotypes and the virulence phenotypes of the isolates, as determined in a previous study.

The importance of monitoring and management of yellow rust, caused by Puccinia striiformis f. sp. tritici (Pst), has markedly increased in Russia over recent years because of intensifying negative effects of this destructive disease on wheat production. The Pst virulence survey was conducted in 2019–2021 in the European (North‐West, Volga, North Caucasus) and Asian (Siberia) parts of Russia, and the same 109 isolates have been genotyped here with 20 SSR markers. Fifty‐three multilocus genotypes (MLGs) were detected, seven of which occurred in two or more regions. The most frequent MLG was found in three European Pst collections (except Dagestan) and Siberia. SSR‐based variation within the regional collections was low because many MLGs were closely related. Nevertheless, each collection contained relatively different small genotype groups. No clear geographic structure of the Russian Pst population was observed because the five studied regional collections shared groups of similar genotypes. The most singular SSR genotype was identified in the North‐West collection, but genotypes of four invasive isolates belonging to the PstS2 temperature‐adapted aggressive strain did not considerably differ from others. The observed heterozygosity at all SSR loci exceeded the expected one in all regional Pst collections, which could imply asexual reproduction of the pathogen. Both the SSR and virulence analyses demonstrated similar patterns of relationships between the regional Pst collections, although the magnitude of differences between the collections was larger for virulence pathotypes. However, no significant association was established between the virulence pathotypes and SSR genotypes because multiple pathotypes had the same genotype and vice versa.
