Common wheat is the main grain crop in Russia. In the last decade, the development of leaf rust caused by the pathogenic fungus Puccinia triticina Erikss on the wheat was enhanced. To increase grain production and obtain environmentally friendly products, it is necessary to use varieties resistant to disease. Common wheat is cultivated over large areas in Western Siberia. In this region an aggressive Asian population of P. triticina, differed from the European one, exists on the crops. For durable defense of varieties from rust diseases, it is necessary to enrich the wheat genome with new resistance genes from the related cereals. The rare species Triticum timopheevii Zhuk. is considered a promising issue of resistance to fungal diseases, but its immunity has been confirmed mainly in the European part of Russia and in North America. The aim of the work was to monitor the resistance of T. timopheevii to leaf rust in Western Siberia and to determine the promising accessions for breeding programs. The adult resistance of T. timopheevii accessions was evaluated in the field conditions on intensive infectious background in 2011-2018 in the South of Western Siberia (Omsk). Additionally the reactions of seedlings to infection were estimated in laboratory. Damage of the plants by leaf rust was characterized by type, score/ percentage. The tendency to shift the type of seedling reaction from immune to susceptible was shown. Beside it the regular weak damage of adult plants of some T. timopheevii specimens was noted in the field in 2014-2018. Among a set of T. timopheevii accessions the promising specimens were determined with stable resistance to the Asian population of P. triticina, which are suitable for breeding programs. The work has begun to include the resistant accessions in the breeding process.

“…leads to significant losses of up to 25-30 % of the crop. In "wheat belt" in Siberia and Northern Kazakhstan an aggressive Asian population of P. triticina exists, which differs in virulence from the European one [4,5]. In recent decades, rust epidemics in the zone were observed every 3-4 years [6].…”

“…Recently, a new pathotype of Ug99 with virulence to Sr24 has been identified in Kenya [57]. However, the genes Lr24 and Sr24 retain their effectiveness in most regions of Russia and Kazakhstan [48,58]. The cultivar is highly drought resistant, able to withstand a prolonged absence of precipitations and high temperatures and is resistant to lodging.…”

The Strategy for Marker-Assisted Breeding of Anthocyanin-Rich Spring Bread Wheat (Triticum aestivum L.) Cultivars in Western Siberia

In wheat, anthocyanin pigments can be accumulated in pericarp tissues (under control of the Pp genes) resulting in purple-colored grain. In the current study, a strategy, based on the use of molecular and morphological markers, was applied to create purple-grained bread wheat cultivars adapted to the West Siberian region. The breeding scheme started from crossing of recipients (elite cultivars and lines) with donor lines carrying dominant alleles of the complementary genes Pp3 and Pp-D1. The F2 hybrids passed three-step marker-assisted selection, and those having dominant Pp-D1Pp-D1Pp3Pp3 genotypes were backcrossed with the recurrent parents. The desired BC1F2-3 progenies were selected using morphological marker, while BC1F3 also passed through field evaluation. At this stage, 120 lines were selected and planted in individual 1 m2 “breeding nursery (BN) plots” for assessment of heading dates, duration of vegetation period, resistance to powdery mildew, stem and leaf rusts, protein and gluten content, as well as productivity. After these investigations, a total of 17 promising anthocyanin-rich purple-grained lines characterized by multiple resistance and having best yield/quality characteristics were finally candidates for selection of commercial cultivars adapted to the West Siberian climate and suitable for functional food production.

“…In the last 100 years, approximately 80 LR resistance genes designated from Lr1 to Lr78, Lrac104, and Lrac124, have been identified and described in common wheat, durum wheat and diploid wheat species (McIntosh et al, 1998(McIntosh et al, , 2007(McIntosh et al, , 2017. In the last 10 years in Kazakhstan, there were active research works on the identification of genes, which are effective against LR, screening of wheat cultivars for the presence of resistance gene (Kokhmetova et al, 2009; Akhmetova et al, 2015) and investigation on population of P. recondita in the country and neighboring territories (Agabaeva, Rsaliev, 2013;Gultyaeva et al, 2018).…”

Identification of QTLs for resistance to leaf and stem rusts in bread wheat (Triticum aestivum L.) using a mapping population of ‘Pamyati Azieva × Paragon’

et al. 2019

Leaf rust (LR) and stem rust (SR) are harmful fungal diseases of bread wheat (Triticum aestivum L.). The purpose of this study was to identify QTLs for resistance to LR and SR that are effective in two wheat-growing regions of Kazakhstan. To accomplish this task, a population of recombinant inbred lines (RILs) of ‘Pamyati Azieva × Paragon’ was grown in the northern and southeastern parts of Kazakhstan, phenotyped for LR/SR severities, and analyzed for key yield components. The study revealed a negative correlation between disease severity and plant productivity in both areas. The mapping population was genotyped using a 20,000 Illumina SNP array. A total of 4595 polymorphic SNP markers were further selected for linkage analysis after filtering based on missing data percentage and segregation distortion. Windows QTL Cartographer was applied to identify QTLs associated with LR and SR resistances in the RIL mapping population studied. Two QTLs for LR resistance and eight for SR resistance were found in the north, and the genetic positions of eight of them have matched the positions of the known Lr and Sr genes, while two QTLs for SR were novel. In the southeast, eight QTLs for LR and one for SR were identified in total. The study is an initial step of the genetic mapping of LR and SR resistance loci of bread wheat in Kazakhstan. Field trials in two areas of the country and the genotyping of the selected mapping population have allowed identification of key QTLs that will be effective in regional breeding projects for better bread wheat productivity.
