Стеблевой хлебный пилильщик Cephus pygmaeus L. относится к серьезным вредителям пшеницы в Алтайском крае. Устойчивость растений-хозяев к этому насекомому основана на выполненности соломины. Влияние данного признака на заселенность стеблей личинками пилильщика и морфобиологические признаки яровой мягкой пшеницы в условиях Алтайского края не изучено.Материалы и методы. Исследование проведено на опытном поле ФГБНУ «Федеральный Алтайский научный центр агробиотехнологий» в 2019–2021 гг. Индекс выполненности соломины оценен по 20-балльной шкале. Взаимосвязь выполненности соломины с заселенностью стеблей пшеницы личинками хлебного пилильщика изучена на 12 генотипах. Влияние выполненности соломины на морфобиологические признаки исследовано на шести парах сестринских линий. По индексу выполненности соломины изучено 100 сортов, по устойчивости к хлебному пилильщику – 184 сорта.Результаты. Коэффициент корреляции Спирмена между индексом выполненности соломины и заселенностью стеблей личинками хлебного пилильщика составил –0,77 в 2019 г. и –0,80 в 2020 г. Линии с выполненной соломиной в среднем за два года характеризовались меньшей высотой растения (–5 см), меньшей озерненностью одного колоска (–0,11 штук), массой 1000 зёрен (–1,7 г) и продуктивностью главного колоса (–0,08 г), но большей массой зерна побегов кущения (+0,11 г). Отрицательного влияния выполненности соломины на урожайность и качество зерна не выявлено. Обнаружено 11 сортов с индексом выполненности соломины &gt; 15 баллов: ‘Ершовская 33’, ‘Изера’, ‘Квинтус’, ‘КВС Аквилон’, ‘Тибальт’, ‘Cunningham’, ‘KW 240-3-13’, ‘KBC 3.13’, ‘Lillian’, ‘Sparrow’, ‘WW-4’.Заключение. Выполненность соломины существенно снижает вред, наносимый стеблевым хлебным пилильщиком, и не сказывается отрицательно на урожайности и показателях качества зерна. Рекомендуется использовать выделенные сорта с выполненной соломиной в селекции пшеницы на устойчивость к хлебному пилильщику.</p></abstract><trans-abstract xml:lang="en"><p>Background. European wheat stem sawfly (Cephus pygmaeus L.) is the main pest of wheat in Altai Territory, Russia. Resistance of host plants to this insect is based on a solid stem. The effect of a solid stem on the infestation of wheat stem sawfly larvae and on agronomic traits of spring bread wheat under the conditions of Altai Territory has not been studied.Materials and methods. The study was conducted on the experimental field of the Federal Altai Scientific Centre of Agro-BioTechnologies, Barnaul, Russia, in 2019–2021. The index of stem solidness was assessed according to a 20 point scale. The interplay between stem solidness and wheat stem sawfly larvae infestation of wheat plants was studied on 12 genotypes. The effect of stem solidness on agronomic traits was studied on 6 pairs of sister lines. One hundred cultivars were studied for the stem solidness index and 184 cultivars were tested for their resistance to wheat stem sawfly.Results. Stem solidness negatively correlated with wheat stem sawfly infestation (Spearman’s rank correlation coefficient was rs  = –0.77 in 2019 and rs  = –0.80 in 2020). Sister lines with a solid stem had significantly shorter plant height (–5 cm), less kernels per spikelet (–0.11 kernels), 1000 grain weight (–1.7 g) and grain weight per spike (–0.08 g), but higher grain weight per tiller spike (+0.11 g), compared to sister lines with a hollow stem averaged over two years. Stem solidness had no negative effect on yield or grain quality. Eleven cultivars with a solid stem index higher than 15 points were identified (‘Ershovskaya 33’, ‘Izera’, ‘Kvintus’, ‘KWS Akvilon’, ‘Tybalt’, ‘Cunningham’, ‘KW 240-3-13’, ‘KWS 3.13’, ‘Lillian’, ‘Sparrow’, ‘WW-4’).Conclusion. Stem solidness significantly decreases the damage from wheat stem sawfly and has no negative effect on yield or gluten and protein content in grain. The abovementioned cultivars with a solid stem are recommended for use in breeding for resistance to wheat stem sawfly. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>урожайность</kwd><kwd>качество зерна</kwd><kwd>вредитель</kwd><kwd>устойчивость</kwd><kwd>селекция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>yield</kwd><kwd>grain quality</kwd><kwd>pest</kwd><kwd>resistance</kwd><kwd>breeding</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>работа выполнена в рамках государственного задания Федерального Алтайского научного центра агробиотехнологий 0534-2021-0003 «Использование молекулярно-генетических и биотехнологических методов исследований в селекции растений».
