Field research was carried out in 2018-2019 on the premises of Omsk Agrarian Research Centre, exactly the breeding crop rotation of the laboratory of durum wheat breeding as well as at the reference point of seed production in the steppe zone in the village of Novouralsky Tavrichesky district of Omsk region. The experiments were conducted in a complete fallow. The area of the plots was 10 m², repeated four times, the location was random. Weather conditions during the vegetation period of 2018 were contrasting both in terms of precipitation and temperature. Grain formation took place in late August - early September, which had a significant impact on grain quality. In 2019, atypical meteorological conditions were observed: favorable in the first vegetation period and arid - in the second (Volga type of drought). The productivity of durum wheat lines was estimated in terms of adaptive capacity and stability. Scientific data on the parameters of grain quality and disease resistance are highlighted. Yields of durum wheat lines varied considerably depending on agro-climatic conditions of the year and cultivation background. The best conditions for the growth and development of genotypes were set up in the southern forest-steppe zone of Omsk, the maximum crop yield was observed in the Gord. line 08-67-1, Gord. 09-68-1, Gord. 05-12-7(v), Gord. 08-107-5. The general adaptive ability is close to zero, that shows stability of genotypes in external environment. Specific adaptive ability revealed in the lines: Gord. 10-33-3, Gord. 10-8-4, Gord. 11- 70-7, Gord. 11-77-8, Gord. 11-99-1. The authors highlight the following promising lines according to the experimental results: Gord. 05-12-7(v), Gord. 08-107-5, Gord. 09-68-1, Gord. 08-67-1. Selection assessment of promising lines was carried out on the indicators of grain quality and disease resistance. The following parameters are seen as good quality indicators at the Gord line 11-70-7: weight of 1000 grains is 49.75 g and high resistance to stem rust (6%). According to the quality of grain and weight of 1000 grains, Gord. line 09-68-1 is better than Zhemchuzhina Sibiri, affection of brown and stem rust is minimal that is interesting for selection procedures. The following varieties are valuable from the point of view of breeding, stability of genotype, high productivity, quality of grain and pasta and resistance to disease: Gord. 05-12-7(v), Gord. 08-107-5, Gord. 09-68-1, Gord. 08-67-1, Gord. 11-70-7, Gord. 11-99-1.

Aim. T. kiharae (AtAtGGDD, 2n=42) is a source of high protein and gluten content, resistance to many diseases. Сommon wheat lines with the introgression of T. kiharae genetic material were obtained in order to enrich T. aestivum L. gene pool. The aim of this study was to assess the impact of T. kiharae genetic material on the grain quality of T. aestivum/T. kiharae introgression lines. Methods. The composition of the high molecular weight glutenin subunits was analyzed by SDS-PAGE. Evaluation of the most important traits of grain quality (hardness, protein and gluten content, gluten quality) was carried out according to GOST. Results. Сomparative analysis of the composition of high molecular weight glutenin subunits of introgressive lines and their parental forms allowed us to identify lines with novel alleles of Glu-1 loci, specific for T. kiharae. For most of the introgression lines T. aestivum/T. kiharae hardness, protein and gluten content were higher than for parent wheat varieties. Conclusions. Introgression of T. kiharaegenetic material in the genome of common wheat had a positive effect on all studied parameters of grain quality except the gluten quality. Keywords: common wheat, T. kiharae, glutenin, SDS-PAGE, quality of grain.

A total of 57 introgression lines and 11 cultivars of spring bread wheat developed by All-Russian Institute of Plant Protection and cultivated in the Volga Region were analyzed. The lines were obtained with the participation of CIMMYT synthetics, durum wheat cultivars, direct crossing with Agropyron elongatum (CI-7-57) and have introgressions from related species of bread wheat, namely translocations from Ag. elongatum (7DS-7DL-7Ae#1L), Aegilops speltoides (2D-2S), Ae. ventricosum (2AL-2AS-2MV#1), Secale cereale (1BL-1R#1S), 6Agi (6D) substitution from Ag. intermedium and triticale Satu. Cultivars and lines were assessed for resistance to Saratov, Lysogorsk, Derbent and Omsk stem rust pathogen populations (Puccinia graminis f. sp. tritici), and analyzed for the presence of the known Sr resistance genes using molecular markers. The analysis of the cultivars’ and lines’ resistance to the Saratov pathogen population in the field, as well as to Omsk, Derbent and Lysogorsk populations at the seedling stage, showed the loss of efficiency of the Sr25 and Sr6Agi genes. The Sr31 gene remained effective. Thirty one wheat lines out of 57 (54.4 % of samples) were resistant to all pathogen populations taken into analysis. The Sr31/Lr26, Sr25/Lr19, Sr28, Sr57/Lr34 and Sr38/Lr37 genes were identified in the introgression lines. The Sr31/Lr26 gene was identified in 19 lines (33.3 % of samples). All lines carrying the 1RS.1BL translocation (Sr31/Lr26) were resistant to all pathogen populations taken into analysis. The Sr25/Lr19 gene was identified in 49 lines (86 %). The gene combination Sr31/Lr26+ Sr25/Lr19 was identified in 15 lines (26.3 %). The gene combinations Sr38/Lr37+Sr25/Lr19, Sr57/Lr34+Sr25/Lr19 and Sr31/Lr26+Sr25/Lr19+Sr28 were identified in 3 introgression lines. These three lines were characterized by resistance to the pathogen populations studied in this work. The Sr2, Sr24, Sr26, Sr32, Sr36 and Sr39 genes were not detected in the analyzed wheat lines.

Related wild and cultural wheat species are regularly involved for expanding T. aestivum genetic diversity because they contain many valuable genes. We evaluated the effect of the genetic material of tetraploid species of the genus Triticum (T. dicoccoides, T. dicoccum) on the grain quality of introgression lines of spring bread wheat. The composition of the high molecular weight glutenin subunits which play an essential role in the formation of wheat baking properties was identified in the introgression lines of bread wheat and their parental forms. The traits of grain quality (hardness, protein and gluten content, gluten quality) were also evaluated. The lines with Glu-1 loci alleles from wheat relatives T. dicoccoides and Т. dicoccum were selected. It was found that the introgression of alien genetic material into the common wheat genome had a positive effect on the parameters of grain quality such as hardness, protein and gluten content. The lines with Glu-A1 loci alleles from T. dicoccoides and Glu-B1 from T. dicoccum were at the level of a parent wheat variety or of a higher gluten quality. As a result of the research, the new lines of bread soft wheat with high grain quality were found and can be used in the crop breeding.
