“…The degree of susceptibility was assessed using a modified Cobb's scale (Peterson et al, 1948). Screening of genotypes for the presence of the Lr6Ai = 2 and LrSp2 genes was performed using the Xicg6Ai = 2 and Xksum73 markers as previously described (Leonova et al, 2017;Adonina et al, 2018).

This paper presents the results of the introduction of leaf rust resistance genes inherited from Th. intermedium and Ae. speltoides into the genome of spring wheat cultivars differing in the length of the vegetation period. A total of 409 F 4 families from cross combinations with the early ripening cultivar Novosibirskaya 15, mid-early 'Novosibirskaya 31' , mid-ripening 'Udacha' and mid-late 'Sibirskaya 17' and the donors of Lr resistance genes 'Tulaikovskaya 10' and 'Chelyaba 75' were studied for leaf rust resistance and the duration of vegetation period. A significant reduction in heading date was revealed in the F 4 lines obtained on the base of the mid-late variety Sibirskaya 17. In contrast, the lines originating from of the 'Udacha' × 'Chelyaba 75' and 'Novosibirskaya 15' × 'Tulaikovskaya 10' crosses were characterized by an elongated period from germination to ear emergence. According to the results of molecular and phytopathological testing, breeding lines were selected that differ in pathogen resistance, length of vegetation period and productivity.

“…Despite the relatively high crop yield of the Chelyaba 75 variety (404.4 g/m 2 ) carrying the LrSp2 gene from Aegilops speltoides Tausch linked to the gametocidal gene (Adonina et al, 2018), which is surely a valuable trait under West Siberian conditions, we were unable to obtain a variety outperforming the current standards while carrying this gene, despite the availability of vast source material (over 4000 lines from crosses between four varieties, namely No vosibirskaya 15, Novosibirskaya 31, Udacha, and Sibir skaya 17) as early as 2015.…”

“…Wheat leaf rust resistance of the Odintsovskaya variety (selection from population Chelyaba 75 х АНК-17В) may be controlled by the LrSp2 gene transferred from Chelya ba 75 and linked to the gametocidal gene (Adonina et al, 2018), since the variety resisted infection, but no ampli fication products of markers linked to other resistance genes were detected. Lr1 gene was detected as a result of genotyping in the Omskaya 44 variety in addition to Lr19 and Lr26 identified earlier by L.V.…”

“…Over 80 Lr genes have been identified around the world, with about 50 % classified as alien ones 1 . The list of genes used in commercial common wheat varieties includes Lr9, Lr19, Lr21, Lr23, Lr24, Lr26, Lr28, Lr37, Lr39 (AktarUzZaman et al, 2017;Leonova, 2018), Lr6Agi1, Lr6Agi2 (Sibikeev et al, 2017), and LrSp2 (Adonina et al, 2018). In Russia, breeding value is assigned to the samples carrying partially effective genes Lr9, Lr19, Lr24, Lr25, Lr26, Lr6Agi1, Lr6Agi2 and highly effective protective genes Lr28, Lr29, Lr39, Lr42, Lr45, Lr47, Lr50, Lr51, Lr66, LrSp2 (Gultyaeva, Shaydayuk, 2021;Sochalova et al, 2022).…”

The relationship between a variety’s genotype, environmental conditions and phytopathogenic load are the key factors contributing to high yields that should be taken into account in selecting donors for resistance and high manifestation of valuable traits. The study of leaf rust resistance in 49 common wheat varieties was carried out in the field against the natural pathogen background and under laboratory conditions using single-pustule isolates with virulence to Lr9 and Lr24. It has been shown that the varieties carrying alien genes Lr6Agi2 (Tulaikovskaya 10) and Lr6Agi1 (Voevoda) were resistant to leaf rust infection both in the field and in the laboratory. Varieties KWS Buran, KWS Akvilon, KW 240-3-13, and Etyud producing crop yields from 417 to 514 g/m2 comparable to the best standard variety Sibirskaya 17 can be reasonably used as Lr24 resistance gene donors under West Siberian conditions. Oms kaya 44 variety showing crop yield of 440g/m2 can be used as a donor for Lr19 and partially effective Lr26. Varieties Tuleevskaya and Altayskaya 110 with Lr9 in their genomes are recommended for the development of resistance gene-pyramided genotypes. The highest protein and gluten contents were observed in the CS2A/2M sample, while KWS Buran, Altayskaya 110, Volgouralskaya, and KWS Akvilon showed the lowest values. Varieties CS2A/2M, Tulaikovskaya 10, Pavon, and Tuleevskaya were ranked the highest in micro- (Cu, Mn, Zn, Fe) and macronutrient (Ca, Mg, K) contents among the common wheat samples from the collection, while the lowest values for most elements were observed in KWS Buran, Novosibirskaya 15, and Volgouralskaya. Winter varieties demonstrating leaf rust resistance against the infectious background typically carry adult plant resistance genes (Lr34, Lr12, and Lr13), particularly combined with the juvenile Lr26 gene. The presence of Lr41 in a winter type line (KS 93 U 62) allowed it to maintain resistance against a leaf rust pathogen clone kLr24, despite the presence of Lr24 in the genotype. Varieties Doka and Cheshskaya 17 may act as donors of resistance genes Lr26 + Lr34 and Lr9 + Lr12 + Lr13 + Lr34, as well as sources of dwarfing without losses in winter hardiness and yield under West Siberian conditions.
