В настоящее время самым распространенным и вредоносным заболеванием огурца является пероноспороз (ложная мучнистая роса). В связи с этим, актуальным направлением селекции остается выведение новых, более устойчивых к пероноспорозу сортов огурца для выращивания в различных регионах. Решение этой задачи требует проведения поиска доноров устойчивости для использования в селекционной работе.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследования проводились в филиале ВИР Волгоградская опытная станция ВИР по общепринятым методикам. Материалом для скрининга послужила коллекция огурца ВИР.</p></sec><sec><title>Результаты и выводы</title><p>Результаты и выводы. В результате многолетнего, на протяжении 32 лет, скрининга 2873 образцов огурца из коллекции ВИР были выявлены 57 устойчивых и относительно устойчивых к пероноспорозу образцов, что составляет 2,0% от числа изученных. Иммунные образцы не найдены. Среди выделившихся форм можно особо отметить образцы с наибольшей продуктивностью: местные образцы из Азербайджана (вр. к.-3999 и вр. к-4004), а также сорта из Китая ‘Zungsungerum-oi’ (вр. к-3701), ‘Tianin mini cucumber’ (к-4490), ‘Tянь узинь яо № 5’ (вр. к-3840), ̔Тянь-узинь ян № 6’ (вр. к-3841). Из числа устойчивых и относительно устойчивых образцов 76% происходили из стран Юго-Восточной Азии. За время изучения 23 образца потеряли свою устойчивость и стали сильно поражаться пероноспорозом. Исходя из этого, можно сделать вывод о необходимости периодических повторных проверок устойчивых образцов. В группу толерантных были выделены 20 образцов. Из них наибольшей средней урожайностью обладают образцы ‘Yeo leam sam chuk oi’ (к-4545), ‘Crispy Top F1’ (вр. к-3549) и ‘Пчелка F1’ (вр. к-3981).</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Currently, the most widespread and harmful disease of cucumber is downy mildew. In this regard, a vitally important trend in cucumber breeding is the development of new cultivars, more resistant to downy mildew, for cultivation in different regions. Solution to this problem requires searching for donors of resistance for use in breeding practice.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The studies were conducted at Volgograd Experiment Station of VIR using conventional methods. The material for the screening was the collection of cucumber genetic resources held by VIR.</p></sec><sec><title>Results and conclusions</title><p>Results and conclusions. During 32 years of work, 2873 cucumber accessions from VIR’s holdings were screened. As a result, 57 accessions with resistance or relative resistance to downy mildew were identified, i. e. 2.0% of the total number studied. Immune accessions were not found. Among the selected accessions, those with the highest yield are noteworthy: landraces from Azerbaijan (temp. k-3999 and temp. k-4004) as well as the cultivars from China ‘Zungsungerum-oi’ (temp. k-3701), ‘Tianin mini cucumber’ (k-4490), ‘Tian Uzin Yao No. 5’ (temp. k-3840) and ‘Tian Uzin Yang No. 6’ (temp. k-3841). Of the resistant and relatively resistant accessions, 76% were from Southeast Asia. During the years of study, 23 accessions, previously resistant to downy mildew, lost their resistance and suffered severe damage from the disease. Hence, it seems obvious that resistant accessions should be periodically retested for susceptibility to downy mildew. Twenty accessions were selected to form a group of tolerant ones. Of these, ‘Yeo leam sam chuk oi’ (k-4545), ‘Crispy Top F1’ (temp. k-3549) and ‘Pchelka F1’ (temp. k-3981) had the highest average yield.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>огурец</kwd><kwd>коллекция</kwd><kwd>пероноспороз</kwd><kwd>источники</kwd><kwd>скрининг</kwd><kwd>устойчивость</kwd><kwd>толерантность</kwd><kwd>урожайность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cucumber</kwd><kwd>collection</kwd><kwd>downy mildew</kwd><kwd>sources</kwd><kwd>screening</kwd><kwd>resistance</kwd><kwd>tolerance</kwd><kwd>yield</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания согласно тематическому плану ВИР по теме № 0662-2019- 0003 «Генетические ресурсы овощных и бахчевых культур мировой коллекции ВИР: эффективные пути расширения разнообразия, раскрытия закономерностей наследственной изменчивости, использования адаптивного потенциала».</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">Буренин В.И., Артемьева А.М., Храпалова И.А., Пискунова Т.М., Кожанова Т.Н., Хмелинская Т.В.
