“…The substitution of wheatgrass chromosome 6Agi2 for 6D does not impair grain yield, grain quality, or drought tolerance (Filatova et al, 2010;Volkova et al, 2010), although in some cases of using T10 as a resistance gene donor, plants with lower productive tillering and 1000 grain weight appeared among the offspring with chromosome 6Agi2 (Stasyuk et al, 2017). The contents of protein and gluten in line 49-14 were about the same as in S29 or T10, corresponding to the grain quality of strong wheats (State Standard…, 2018.…”

Wheatgrass Thinopyrum intermedium is a source of agronomically valuable traits for common wheat. Partial wheat–wheatgrass amphidiploids and lines with wheatgrass chromosome substitutions are extensively used as intermediates in breeding programs. Line Agis 1 (6Agi2/6D) is present in the cultivar Tulaykovskaya 10 pedigree. Wheatgrass chromosome 6Agi2 carries multiple resistance to fungal diseases in various ecogeographical zones. In this work, we studied the transfer of chromosome 6Agi2 in hybrid populations Saratovskaya 29×Tulaykovskaya 10 (S29×T10) and Tulaykovskaya 10×Saratovskaya 29 (T10×S29). Chromosome 6Agi2 was identified by PCR with chromosome-specific primers and by genomic in situ hybridization (GISH). According to molecular data, 6Agi2 was transmitted to nearly half of the plants tested in the F2 and F3 generations. A new breeding line 49-14 (2n = 42) with chromosome pair 6Agi2 was isolated and characterized in T10×S29 F5 by GISH. According to the results of our field experiment in 2020, the line had high productivity traits. The grain weights per plant (10.04±0.93 g) and the number of grains per plant (259.36±22.49) did not differ significantly from the parent varieties. The number of grains per spikelet in the main spike was significantly higher than in S29 (p ≤ 0.001) or T10 (p ≤ 0.05). Plants were characterized by the ability to set 3.77±0.1 grains per spikelet, and this trait varied among individuals from 2.93 to 4.62. The grain protein content was 17.91 %, and the gluten content, 40.55 %. According to the screening for fungal disease resistance carried out in the field in 2018 and 2020, chromosome 6Agi2 makes plants retain immunity to the West Siberian population of brown rust and to dominant races of stem rust. It also provides medium resistant and medium susceptible types of response to yellow rust. The possibility of using lines/varieties of bread wheat with wheatgrass chromosomes 6Agi2 in breeding in order to increase protein content in the grain, to confer resistance to leaf diseases on plants and to create multiflowered forms is discussed.

“…Оказалось, что среди многих успешных переносов генетического материала ржи в геном пшеницы только две транслокации имеют практическую ценность, причем в обоих случаях в этих транслокациях прини мает участие хромосома 1RS. Транслокация 1RS.1BL, перенесенная в пшеницу от сортов ржи Аврора и Кавказ, содержит комплекс генов устойчивости к бурой (Lr26), стеблевой (Sr31), желтой (Yr9) ржавчинам и мучнистой росе (Pm8) и используется в основном в сортах европей (McIntosh et al, 1995;Friebe et al, 1996;Volkova et al, 2010;Kazi et al, 2013;Tomar et al, 2014;Tyunin et al, 2017; http://maswheat.ucdavis.edu/). ** In limited use: Varieties and lines are used as sources and donors of L genes.…”

“…Сорта мягкой пше ницы Тулайковская 10, Тулайковская золотистая, Тулай ковская 100, Волгоуральская c генетическим материалом 6Ai#2 имеют длительную устойчивость к популяциям бурой ржавчины, специфичным для европейской части России, Уральского и ЗападноСибирского регионов (Пла хотник и др., 2014; Leonova et al, 2017a). Несмотря на полное замещение хромосомы 6D на хромосому 6Ai#2, для этих сортов характерны высокие показатели урожай ности, засухоустойчивость и хорошие хлебопекарные качества (Volkova et al, 2010). Однако использование сорта Тулайковская 10 в качестве донора генов устойчивости показывает, что среди потомства, содержащего хромосому 6Ai#2, выявляются образцы, у которых наблюдается сни жение числа продуктивных побегов и массы 1 000 зерен (Стасюк и др., 2017).…”

Analysis of the technological qualities of spring wheat grain showed, that high-natural grain can be obtained from the varieties of Orenburg and Samara selection in 75.0% of the years, and the Saratov breeding - 62.5% of years. All studied varieties of spring durum wheat form high-natural grains of 87.5% years. Grain with high glassiness is characteristic to varieties of spring wheat of Samara breeding of 75.0% years and Orenburg and Saratov breeding - 87.5% years. High glassiness grain of spring durum wheat varities of Samara and Saratov breeding constitute 87.5% of the years, and the Orenburg selection of 100% of the years. Grain, which protein content is greater than 14% or more in Orenburg steppe, was formed only by varieties of soft wheat Orenburg breeding and Ukrainian durum wheat breeding in years of 12.5%. Grain, corresponding to 1 class by the content of gluten, in our experiments was obtained from following varieties: soft wheat of Orenburg and Samara selection in 75.0% of the years, and the Saratov - in 62.5% of the years; durum wheat of Orenburg and Samara selection in 25.0% of the years, and Ukrainian - 62.5% years. The investigation of soft wheat varieties form grain of I-III quality group and grade durum wheat - II-III quality group.
