“…The objects of the study were four cultivars of winter wheat. They were selected according to the degree of resistance to various diseases [ 23 , 24 ]: “Kuren” (resistant to brown and yellow rust, moderately resistant to powdery mildew, moderately susceptible to septoria and yellow spot), “Bonus” (resistant to leaf rust and powdery mildew, moderately susceptible to septoria leaf spot, susceptible to yellow rust and yellow spot), “Aksinya” (resistant to leaf rust, moderately resistant to yellow rust, moderately susceptible to powdery mildew and septoria leaf spot, susceptible to yellow spot), “Krasnodarskaya 99” (resistant to yellow rust, moderately resistant to powdery mildew and septoria leaf spot, moderately susceptible to yellow spot, susceptible to leaf rust). The plot area of each cultivar was 20 m 2 in triplicate.…”

Leaf airborne diseases cause major shortfalls in agricultural crops. The introduction of technical means can significantly improve early-warning systems for plant diseases as well as provide timely and accurate forecasts. In this paper, we aim to evaluate the possibilities of detecting a phytopathogenic infection using a spore-catching device developed at the Federal Research Center of Biological Plant Protection (FRCBPP) on winter wheat varieties of different levels of susceptibility to major economically important leaf diseases, taking into account climatic conditions. The device captures spores in the surface layer of air among crop plants. We conducted research in the experimental fields of FRCBPP in 2019–2021. The objects of the study were four cultivars of winter wheat. They were selected according to the degree of resistance to various leaf diseases. We studied the progress of wheat diseases according to generally accepted international scales the onset of the first manifestations to their maximum development. We studied the aerogenic infection in wheat crops using the FRCBPP developed portable device for determining the infestation of plants. Sampling was carried out in the same period as the visual assessment. The samples were taken in the crops of each variety at five points. The sampling time was one minute. As a result of research on experimental crops of four varieties of winter wheat, we observed the development of such diseases as powdery mildew (Erysiphe graminis), yellow spot (Pyrenophora tritici-repentis), septoria leaf spot (Septoria tritici), yellow (Puccinia striiformis) and brown rust (Puccinia triticina). In a laboratory study of samples under a light microscope, all of the listed pathogens were found except for septoria leaf spot. Two-way analysis of variance confirmed the statistically significant separate and cumulative influence of the cultivar and year factor on winter wheat diseases. A generalized correlation analysis for three growing seasons (2019–2021) showed that an average statistically significant correlation coefficient (0.5–0.6) remains for the total groups for powdery mildew, yellow and brown rust. This indicator for the causative agent of yellow spot was equal to 0.4 with a high level of statistical significance. Thus, we conclude that by using a spore-catching device, it is possible to identify spores of economically significant pathogens in winter wheat crops and predict the further development of pathogens, taking into account the cultivar and annual climate factors.

В статье представлены результаты совместных многолетних иммунологических исследований сортов и селекционных линий озимой пшеницы селекции ФГБНУ «АНЦ «Донской» к северокавказской популяции возбудителя желтой ржавчины, проведенные при искусственном заражении в различных агроэкологических условиях (г. Зерноград, Ростовская область-ФГБНУ «АНЦ «Донской» и г. Краснодар-ФГБНУ «ВНИИБЗР»). Желтая ржавчина (возбудитель Puccinia striiformis f. sp. tritici West.) является опасным заболеванием пшеницы во всех регионах мира, возделывающих зерно, в том числе и на юге России. В годы с благоприятными условиями потери урожая пшеницы от данного патогена могут достигать 70-100%. Одним из наиболее эффективных методов защиты пшеницы является выращивание устойчивых к патогену сортов. Для их создания необходим регулярный скрининг источников устойчивости среди сортов и линий пшеницы различной селекции. В условиях полевых стационаров ФГБНУ «АНЦ «Донской» (2014-2016 гг.) и ФГБНУ «ВНИИБЗР» (2017-2019 гг.) на искусственных инфекционных фонах P. striiformis прошли испытание селекционные и коллекционные сорта и сортообразцы пшеницы, созданные в отделе селекции и семеноводства озимой пшеницы ФГБНУ «Аграрный научный центр «Донской». На протяжении 40 последних лет донские селекционеры, привлекая различные источники и доноры устойчивости, создавали сорта пшеницы с высокой устойчивостью к основным болезням, в том числе и к желтой ржавчине. Это сорта Донская безостая, Дон 85, Донщина, Колос Дона, Зерноградка 8, Дон 93, Дон 95, Донской маяк и др. В результате проведенных исследований в различных агроклиматических зонах среди изученного материала установлена высокая доля (от 52,0 до 87,3%) устойчивых к желтой ржавчине сортов и сортообразцов. Высокую устойчивость, по многолетним данным, проявляют сорта озимой мягкой пшени
