Засуха моделировалась прекращением полива, устойчивость растений оценивалась по изменениям показателей флуоресценции хлорофилла (Fv /Fm, Y(II), NPQ) и морфометрических показателей (длина листьев, сырая и сухая масса) по сравнению с контрольной группой с нормальным водообеспечением. В бесстрессовых условиях растения сорта Леон демонстрировали статистически значимо меньшую эффективность фотосинтеза по параметрам Y(II) и Fv /Fm (0,535 ± 0,005 и 0,776 ± 0,004 соответственно) в сравнении с другими сортами (0,577 ± 0,005 и 0,788 ± 0,001 – для сорта Фокс 1; 0,574 ± 0,004 и 0,787 ± 0,001 – для сорта Ратник). При моделировании засухи отмечено снижение всех морфометрических показателей относительно контроля для всех сортов с наибольшей степенью угнетения для сорта Ратник (70,16 ± 3,88 %; 8,09 ± 0,73 %; 68,50 ± 4,42 % для длины листьев, сырой и сухой массы соответственно) и наименьшей – для сорта Леон (88,06 ± 7,83 %; 26,51 ± 7,11 %; 79,32 ± 11,17 % соответственно). Снижение интенсивности фотосинтеза проявлялось в подавлении Fv /Fm и Y(II) и увеличении NPQ с наиболее ранними изменениями параметров Y(II) и NPQ у Фокс 1 и Ратник (на 4-й и 5-й день соответственно) по сравнению с Леон (на 7-й день). В полевых условиях оценивалась урожайность сортов и ее зависимость от количества осадков. Выявлена положительная корреляция между разностью урожайности двух контрастных по ответу на засуху сортов Леон и Ратник и количеством осадков в период активной вегетации в 2014–2017 и 2022 гг. (R2-Пирсона = 0,77, р &lt; 0,05). Наиболее чувствительными параметрами фотосинтеза, по которым можно прогнозировать устойчивость к недостатку влаги, представляются Y(II) и NPQ.</p></abstract><trans-abstract xml:lang="en"><p>   The purpose of the current work was to identify photosynthetic parameters that are predictors of barley drought tolerance, determined at early stages of development, and to verify the results obtained in field conditions.   The study was carried out with the barley varieties ‘Leon’, ‘Ratnik’ and ‘Foks 1’, used in mutation breeding to develop drought-resistant genotypes. Drought was modeled by stopping irrigation. Plant resistance was estimated by changes in chlorophyll fluorescence (Fv /Fm, Y(II), NPQ) and morphometric parameters (leaf length, wet and dry weight) compared to the control group with normal water supply. Under stress-free conditions, the variety ‘Leon’ demonstrated a statistically significantly lower efficiency of photosynthesis in terms of Y(II) and Fv /Fm (0.535 ± 0.005 and 0.776 ± 0.004, respectively) in comparison with other varieties (0.577 ± 0.005 and 0.788 ± 0.001 for the variety ‘Foks 1’; 0.574 ± 0.004 and 0.787 ± 0.001 for the variety ‘Ratnik’). When modeling drought, there has been established a decrease in all morphometric indicators for all varieties relative to the control, with the highest degree of inhibition for the variety ‘Ratnik’ (70.16 ± 3.88 %; 8.09 ± 0.73 %; 68.50 ± 4.42 % for leaf length, wet and dry weight, respectively) and with the lowest degree for the variety ‘Leon’ (88.06 ± 7.83 %; 26.51 ± 7.11 %; 79.32 ± 11.17 %, respectively). A decrease in the photosynthesis intensity was manifested in the suppression of Fv /Fm and Y(II) and an increase in NPQ, with the earliest changes in the parameters Y(II) and NPQ in the varieties ‘Foks 1’ and ‘Ratnik’ (on the 4th and 5th day, respectively), compared to the variety ‘Leon’ (on the 7th day). In the field conditions, there has been estimated productivity of the varieties and its dependence on precipitation. A positive correlation between the difference in yield of two varieties ‘Leon’ and ‘Ratnik’, contrasting in their response to drought, and the amount of precipitation during the active vegetation period in 2014–2017 and 2022 (Pearson’s R2 = 0.77, p &lt; 0.05) has been identified. The most sensitive parameters of photosynthesis, which can be used to predict resistance to moisture deficiency, were Y(II) and NPQ.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фенотипирование</kwd><kwd>фотосинтез</kwd><kwd>урожайность</kwd><kwd>засуха</kwd><kwd>Hordeum vulgare</kwd><kwd>перспективные линии ячменя</kwd></kwd-group><kwd-group xml:lang="en"><kwd>phenotyping</kwd><kwd>photosynthesis</kwd><kwd>productivity</kwd><kwd>drought</kwd><kwd>Hordeum vulgare</kwd><kwd>promising barley lines</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Результаты получены при финансовой поддержке Российской Федерации в лице Министерства науки и высшего образования РФ (Соглашение № 075-15- 2021-1068 от 28. 09. 2021)</funding-statement><funding-statement xml:lang="en">results received with financial support from the Russian Federation represented by the Ministry of Science and Higher Education of the Russian Federation (Agreement No. 075-15-2021-1068 from 09/28/2021)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Доспехов Б.
