“…It should also be noted that Western Siberia is characterized by the presence of aggressive population of the stem rust pathogen. This was demonstrated by the assessment results of the collection of isogenic lines and cultivars with known genes of resistance to stem rust, which showed differentiation only at the first assessment of the damage, and later the results were negated due to a strong disease development (Lapochkina et al, 2016), as well as by the results of the study on the racial composition of Western Siberian populations of this pathogen (Skolotneva et al, 2020).…”

“…The genetic diversity of Sr genes among spring and winter wheat plants differed. Nine main gene combinations in spring plants The evaluation of the progeny of 198 bread wheat spring lines and 367 lines of winter wheat with two-three Sr resistance genes was conducted in various geographical points of the Russian Federation to leaf and stem rust, differing in the spectrum of virulence genes (Lapochkina et al, 2016(Lapochkina et al, , 2018. This resulted in the selection of lines with group resistance to both pathogens (Table 2).…”

An original initial material of spring and winter bread wheat with group resistance to stem and leaf rust was developed using new donors of resistance to stem rust: winter soft wheat GT 96/90 (Bulgaria) and accession 119/4-06rw with genetic material of the species Triticum migushovae and (Aegilops speltoides and Secale cereale), respectively, a line of spring wheat 113/00i-4 obtained using the species Ae. triuncialis and T. kiharae, as well as spring accession 145/00i with genetic material of the species Ae. speltoides resistant to leaf rust. The transfer of effective Sr-genes to progeny was monitored using molecular markers. New lines underwent a field assessment of resistance to leaf and stem rust in the epiphytotic development of diseases in the Central Region of the Russian Federation, as well as in the North Caucasus and Western Siberia, and showed high resistance to these pathogens. Fourteen genotypes of spring wheat with group resistance to these diseases and parental forms that participated in the origin of the lines were evaluated for resistance to spot blotch (Cochliobolus sativus) and tan spot (Pyrenophora tritici-repentis) using isolates from Kazakhstan and Omsk in laboratory conditions. A highly resistant parental form of winter soft wheat from “Arsenal” collection 119/4-06rw (wheat-Ae. speltoides-rye hybrid 2n = 42) with group resistance to two spots, four medium-resistant genotypes to both isolates of tan spot from Kazakhstan and Omsk populations of the pathogen, as well as genotypes resistant to the Omsk isolate of P. triticirepentis (parental form 113/00i-4 and lines 1-16i, 6-16i, 9-16i) were isolated. Among the lines of winter wheat, four were identified with group resistance to spot blotch and tan spot. Additionally, the stress resistance of the lines to NaCl salinization and prolonged flooding of seeds with water was evaluated at the early stages of ontogenesis in laboratory conditions. Lines 33-16i, 37-16i, 32-16i and 9-16i showed a high ability to withstand excess moisture. Lines 33-16i, 37-16i, 32-16i and 3-16i were characterized by high salt tolerance, exceeding the average of 49.7 %. Among the winter genotypes, lines were identified with increased resistance to hypoxia (37-19w, 32-19w, 16-19w, 90-19w) and with increased salt tolerance (20-19w, 9-19w, 37-19w, 90-19w), significantly exceeding the standard cv. Moskovskaya 39. The listed lines are of interest as sources of resistance to anaerobic and salt stress, as well as donors of resistance to a group of fungal diseases: leaf and stem rust and tan spot. We attribute the increased level of resistance of the new initial material to the presence of alien translocations in the original parental forms involved in the origin of the lines.

“…Therefore, in breeding new varieties, Siberian breeders have to overcome great difficulties. Nevertheless, valuable and strong wheat varieties have been bred in such extreme conditions of the region, and every fifth loaf of bread in the country is baked from the grain of these varieties Likhenko et al, 2018;Lapochkina et al, 2017;Likhenko et al, 2015).…”

Over the past century and at the beginning of the current one, Siberian breeders have been intensively breeding spring soft wheat for improving the yield and grain quality. The ecologically and geographically diverse source material has been used at the breeding and educational institutions of the region. Thus, in the severe Siberian conditions, the wheat gene pool has been painstakingly created. It has been very difficult here to solve the problem of improving the grain quality, but, given the determination and the talent of many breeders and geneticists, the gene pool of valuable and strong wheat varieties has been created. As a result, being formerly a consumer of food wheat, Siberia has now become a region producing high-quality grain for domestic use and sale in the foreign market. The gene pool of spring soft wheat, which is so rich in the volume and quality, has not been studied in full, and not used throughout Siberia. In 2013 – 2015, sixteen valuable and strong varieties of Siberia-bred wheat had been studied in the northern zone of the Tyumen region on the experimental field of the Northern Trans-Ural State Agricultural University. It has been found that the average productivity of the early-ripening Novosibirskaya 16, Tulun 15, and Polyushko varieties over the three years amounted to 2.52 – 2.89 t/ha, and was close to the yield (2.35 – 3.10 t/ha) of the middle-early ripening varieties. In the midseason-ripening group, the Alyoshina and Altayskaya 110 and 325 varieties exceeded the Tyumen-bred standard Lutescens 70 by 0.23 – 0.69 t/ha with the yield of the latter being 2.54 t/ha. In terms of the content and quality of gluten, the following varieties stood out: Iren, Novosibirskaya 15, Tulun 15, Polyushko, Omskaya 36, Skala, Boyevchanka, Pamyati Vavenkova, Tyumenskaya 80, Alyoshina, and Altayskaya 325. In terms of baking properties (3.7 – 4.2 points), the following varieties stood out: Iren, Novosibirskaya 15, 29, 31, Polyushko, Skala, Boyevchanka, Pamyati Vavenkova, Tyumenskaya 80, Tulunskaya 12, and Altayskaya 325, which can be used as the source material for further wheat breeding.

Cultivation of winter wheat varieties in the West Siberian region of Russia has competitive advantages compared to spring varieties: utilization of spring-summer moisture, early maturation and harvest and a high yield potential. The poor resistance of winter varieties to foliar diseases results in significant yield losses and facilitates the spread of pathogens to the spring wheat cultivars. The present study was conducted to evaluate the effectiveness of molecular markers specific for VRN-1 and Lr loci in selecting winter wheat genotypes resistant to leaf rust. The winter wheat cultivars Biyskaya ozymaya and Filatovka were crossed with spring wheat introgression lines 21-4 and 5366-180 and the spring wheat cultivar Tulaikovskaya 10 carrying LrTt2, LrAsp5 and Lr6Ai#2 loci from Triticum timopheevii, Aegilops speltoides and Thynopyrum intermedium, respectively. To identify winter wheat plants homozygous for target loci, F 2 populations were screened with functional markers to VRN-1 genes and with markers specific for alien genetic material. Based on the genotyping analysis of 371 F 2 plants a total of 44 homozygous genotypes with winter habit was identified. There were eight genotypes containing Lr loci among them. Evaluation of F 2-derived F 3-4 families for both seedling and adult resistance showed that only one F 3-4 family had moderate susceptible reaction type to the field population of leaf rust. Others ranged from nearly immune to resistant with severity of 5%. The data also indicated the utility of the VRN-1 allele-specific markers for detection of genotypes with winter habit without vernalization at early stages of plant breeding.
