In an effort to enhance wheat's resilience against rust diseases, our research explores the genetic underpinnings of resistance in a diverse collection winter bread wheat accessions. Leaf (Puccinia triticina), yellow striiformis f. sp. tritici), and stem graminis tritici) are significant threats global production. By leveraging host resistance, we can improve disease management strategies. Our study evaluated 55 accessions, including germplasm from Kazakhstan, Uzbekistan, Russia,...

The Volga region is one of the main grain-producing regions Russia. Wheat stem rust caused by Puccinia graminis f. sp. tritici among most destructive fungal diseases wheat. Recently, its harmfulness has increased in region. In this regard, an analysis resistance and diversity Sr genes Russian wheat cultivars necessary. work, 126 (including 23 durum 103 bread cultivars) approved for use were evaluated their to two samples P. populations from different areas at seedling stage. Specific DNA...
A collection of 183 monoconidial isolates the causal agent wheat tan spot Pyrenophora tritici-repentis was created. It is represented by 7 populations different geographical origins isolated in 2017 and 2018: two "southern" from Krasnodar South Kazakhstan (Almaty), "northern" – Finland Northwest West Siberian (Northern Kazakhstan, Chelyabinsk Omsk) regions Russian Federation. The composition races presence ToxA ToxB genes pathogen were determined PCR. gene not detected tested. All southern...
A total of 57 introgression lines and 11 cultivars spring bread wheat developed by All-Russian Institute Plant Protection cultivated in the Volga Region were analyzed. The obtained with participation CIMMYT synthetics, durum cultivars, direct crossing Agropyron elongatum (CI-7-57) have introgressions from related species wheat, namely translocations Ag. (7DS-7DL-7Ae#1L), Aegilops speltoides (2D-2S), Ae. ventricosum (2AL-2AS-2MV#1), Secale cereale (1BL-1R#1S), 6Agi (6D) substitution...
Tan spot caused by Pyrenophora tritici-repentis (Died.) Drechsler, in recent years, occupies an increasingly large area on the territory of Russia. Due to wide distribution and economic significance this disease, search for resistant plants pathogen is relevant. This paper presents results a field assessment 2017–2019 34 regionally distributed winter wheat varieties Russian selection resistance P. North Caucasus region Field - development disease up 30% against background artificial...
Background . The most effective and environmentally safe way to combat wheat diseases is produce cultivars resistant their pathogens. For this purpose, old landraces are often used as genetically diverse sources of traits important for breeding. In the process breeding resistance tan spot caused by fungus Pyrenophora tritici-repentis (Died.) Drechs. (abbr. Ptr), selection carried out against dominant allele Tsn1 , gene sensitivity toxin Ptr ToxA, which induces necrosis represents main...
The most widespread and harmful disease of barley is net form blotch caused by the ascomycete Pyrenophora teres f. Drechsler (Ptt). A cost effective environmentally sustainable strategy for protection against Ptt to develop cultivars possessing genetic resistance. In previous GWA analysis, we identified SNP-markers associated with a resistance locus on chromosome 3H in interval 45.82–54.53 cM. These SNPs have been described previously literature be located within same region 3H. aim study...
Wheat is one of the most important food crops in Russia. Rust diseases (leaf, yellow and stem rusts) are particularly dangerous wheat that threaten security. The rust (the causative agent a biotrophic fungus Puccinia graminis f. sp. tritici) damaging; crop losses can reach 50 to 80% more. paper presents results analysis resistance 189 introgressive lines spring soft breeding ARISER 11 varieties cultivated Lower Volga region growing season 2016-2020. phytopathological assessment virulence...
Background. Due to the increase in harmfulness of wheat stem rust ( Puccinia graminis f. sp. tritici Erikss. & E. Henn.) Volga region, and likelihood spread aggressive Ug99 race, an assessment genetic diversity breeding lines identification effective Sr genes are fundamental importance. Materials methods. Ninety spring bread introgressive with resistance, developed at Federal Center Agriculture Research South-East Region, were analyzed. Molecular markers used identify resistance genes:...
The aim of this research is to develop for the Russian Federation Non-Cher nozem Zone competitive prototypes winter wheat cul tivars with several genes resistance stem rust (in clu ding race Ug99) based on new sources use molecular markers. individual plants and then lines common effective Ug99 were selected by means marker assistant selection out hybrid combinations from crossing donors dangerous disease. development initial material was VIR “Arsenal” collections. Three accessions...
Genetic resistance to net form of blotch in the international barley differential Canadian Lake Shore (CLS) was characterized and mapped. A doubled haploid (DH) population generated from a cross between CLS susceptible cultivar Harrington evaluated at seedling stage using eight diverse Pyrenophora teres f. (Ptt) isolates adult field natural inoculum. To effectively map resistance, comparative marker frequency analysis (MFA) performed 8,762 polymorphic DArT-seq markers, where 'resistant'...
The Sr22, Sr35, and Sr25 genes attract the attention of bread wheat breeders with their effectiveness against Puccinia graminis f. sp. tritici race Ug99 its biotypes. impact Sr22+Sr25 Sr35+Sr25 gene combinations on agronomic traits have not yet been studied. In present article, these were studied using spring lines L503/W3534//L503, L503/Sr35//L503/3/L503 carrying during 2016–2020. These assessed for resistance to P. under natural epiphytotics Saratov, Lysogorsk Omsk populations pathogen...
Donors of resistance common wheat to stem rust race Ug99 (breeding lines GT 96/90, 113/00i-4 and 119/4-06rw) are involved in cross breeding with the use step crossing backcrossing method. While developing hybrids spring mode life, donor (Sr2, Sr36, Sr39, Sr40, Sr44, Sr47) accession 145/05i, which is resistant leaf under conditions RF Central Region but susceptible Ug99, were used for backcrossing, 137 individual plants homozygotic state alleles 2–5 genes selected from obtained hybrid...
Wheat stem rust, caused by Puccinia graminis f. sp. tritici, which used to be a harmful disease of winter wheat in the southern part Russia, has been largely affecting yield spring bread territories temperate climate zone since 2009. In total, 222 P. tritici isolates were obtained from samples susceptible cultivars Central and Volga regions Omsk Novosibirsk provinces 2019. Genotyping was carried out at 16 simple-sequence repeat (SSR) loci. Number alleles, proportion heterozygotes, deviation...
The need for new donors of resistance to aggressive race Ug99 Puccinia graminis Pers. f. sp. tritici Eriks. et Henn has arisen because the pest approaches territory Russian Federation. Identification seventeen known Sr genes was performed with use molecular markers in six sources stem rust Ug99. They included five common wheat lines and Donskaya Polukarlikovaya cv. investigated accessions carried genetic material alien species (Aegilops speltoides, Aе. triuncialis, Secale cereale). We used...
Harmfulness of stem rust (Puccinia graminis f. sp. tritici) constantly increases and virulent races, including Ug99 group, are spreading on the territory Russian Federation. Analysis diversity in resistance genes (Sr genes) wheat varieties is therefore great importance. In this study, 32 new soft varieties, included State Register Breeding Achievements 2017–2018, were evaluated for to at seedling stage, Sr identified using molecular markers. To analyze Omsk pathogen population 2018 years was...
