Однако ее влияние на хозяйственно полезные показатели изучено недостаточно. В представленной статье исследована агрономическая ценность транслокации 7DL-7Ae#1L·7Ae#1S у аналогов яровой мягкой пшеницы сортов Саратовская 68 и Саратовская 70 в течение 2019–2021 гг. Наличие гена Lr29 у исследуемого материала было подтверждено с помощью ПЦР-анализа с маркером Lr29F24. Линии с геном Lr29 характеризовались высокой устойчивостью к Puccinia triticina как на фоне естественной эпифитотии, так и в лабораторных условиях. Транслокация 7DL-7Ae#1L·7Ae#1S у аналогов сорта Саратовская 68 снижала продуктивность зерна во все годы исследований. В среднем понижение составило 35 и 42 %, или в абсолютных цифрах 1163 и 1039 против 1802 кг/ га у сорта-реципиента. В то же время у линий-аналогов сорта Саратовская 70 отмечено понижение урожайности зерна в 2019 и 2020 гг. и не было отличий в 2021 г. В среднем понижение урожайности было 18 и 32 %, или в абсолютных цифрах 1101 и 912 против 1342 кг/ га у сорта-реципиента. У аналогов обоих сортов выявлено значимое понижение массы 1000 зерен, которое колебалось от 14 до 20 % на сорте Саратовская 68 и 17–18 % – на сорте Саратовская 70. Увеличение периода «всходы–колошение» обнаружено только у линий-аналогов сорта Саратовская 68, которое составило в среднем 1.3 суток. У аналога сорта Саратовская 70 различий по этому показателю не было. Транслокация 7DL-7Ae#1L·7Ae#1S не влияла на высоту растений и устойчивость к полеганию у всего набора линий. Исследования качества муки и хлеба у линий с транслокацией 7DL-7Ae#1L·7Ae#1S выявили значимое увеличение содержания зернового белка и клейковины. Однако наблюдались различия между линиями сортов Саратовская 68 и Саратовская 70 по влиянию на показатели альвеографа. Если у линий сорта Саратовская 68 отмечалось понижение упругости, отношения упругости теста к растяжимости, то у линий сорта Саратовская 70 эти показатели повышались. Все линии увеличивали силу муки и объем хлебцев, но если у линий сорта Саратовская 68 была повышенная хлебопекарная оценка, то линии сорта Саратовская 70 не отличались от реципиента.</p></abstract><trans-abstract xml:lang="en"><p>The 7DL-7Ae#1L·7Ae#1S translocation with the Lr29 gene attracts the attention of bread wheat breeders by its effectiveness against Puccinia triticina. However, its impact on useful agronomic traits has been little studied. In this report, the prebreeding value of 7DL-7Ae#1L·7Ae#1S was studied in analogue lines (ALs) of spring bread wheat cultivars Saratovskaya 68 and Saratovskaya 70 during 2019–2021. The presence of the Lr29 gene was conf irmed by using molecular marker Lr29F24. The ALs with the Lr29 gene were highly resistant to P. triticina against a natural epiphytotics background and in laboratory conditions. 7DL-7Ae#1L·7Ae#1S in Saratovskaya 68 ALs reduced grain productivity in all years of research. On average, the decrease was 35 and 42 %, or in absolute f igures 1163 and 1039 against 1802 kg/ha in the cultivar-recipient. In Saratovskaya 70 ALs, there was a decrease in grain yield in 2019 and 2020, and there were no differences in 2021. On average, the decrease was 18 and 32 %, or in absolute f igures 1101 and 912 against 1342 kg/ha in the cultivar-recipient. The analogues of both cultivars showed a signif icant decrease in the weight of 1000 grains, which ranged from 14 to 20 % for Saratovskaya 68 and 17–18 % for Saratovskaya 70. An increase in the period of germination-earing was noted only in Saratovskaya 68 lines, which averaged 1.3 days. ALs of Saratovskaya 70 had no differences in this trait. 7DL-7Ae#1L·7Ae#1S did not affect plant height and lodging resistance in all ALs. Studies of the bread-making quality in lines with 7DL-7Ae#1L·7Ae#1S revealed a signif icant increase in grain protein and gluten content. As for the effect on the alveograph indicators, there were differences between ALs of both cultivars. While Saratovskaya 68 ALs had a decrease in elasticity and in the ratio of dough tenacity to the extensibility, Saratovskaya 70 lines had an increase in these indicators. All lines increased the f lour strength and the loaves volume, but while Saratovskaya 68 ALs had an increased porosity rating, Saratovskaya 70 ALs had the same rating as the recipient.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>мягкая пшеница</kwd><kwd>транслокация 7DL-7Ae#1L·7Ae#1S</kwd><kwd>линии-аналоги</kwd><kwd>эффективность гена Lr29</kwd><kwd>влияние на продуктивность и качество зерна</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bread wheat</kwd><kwd>translocation 7DL-7Ae#1L·7Ae#1S</kwd><kwd>analogue lines</kwd><kwd>eff iciency of the Lr29 gene</kwd><kwd>effect on grain productivity and bread-making quality</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Atia M.A.M., El-Khateeb E.A., Abd El-Maksoud R.M., Abou-Zeid M.A., Salah A., Abdel-Hamid A.M.E.
