Изучено 19 ранее созданных отборных форм по компонентам зимостойкости в контролируемых условиях, устойчивости к основным грибным заболеваниям, компонентам продуктивности, прочности и биохимическому составу плодов. В качестве контроля выступал районированный сорт Гусар. Работа проводилась в 20182020 гг. согласно общепринятым методикам. Искусственное промораживание стеблей малины проводили в климатической камере TH-6 JEIO TECH. По результатам исследований выделены отборные формы 8-10х-1, 6-125-4, обладающие повышенной устойчивостью к отдельным компонентам зимостойкости. Совокупной устойчивостью к зимним повреждающим факторам обладали гибриды 2-115-1 и 1-188-1. По комплексной устойчивости гибридов малины к основным грибным заболеваниям выделились новые источники: формы 1-124-1, 2-115-1, 2-115-2, 1-111-21, 1-8-2, 2-35-1, 2-90-3, 6-125-4, 3-4-2, 8-10х-1, 4-33-21 и 4-122-2. Степень их поражения не оказывала значительного влияния на зимостойкость, продуктивность и качество ягод. По результатам изучения компонентов продуктивности малины были выделены отборные формы (1-111-21, 2-90-2 и 2-90-3), формирующие плоды средней массой более 4,0 г, и генотипы с крупными и одномерными плодами (1-176-21, 2-35-1, 4-33-21, 1-124-1), не мельчающими от сбора к сбору. Наибольшей потенциальной продуктивностью отмечены отборы 2-115-1, 1-111-21, 1-188-1, 4-46-2, 2-90-2 и 2-90-3, способные формировать урожай более 1,3 кг с куста. Повышенной прочностью плодов отличались отборы 1-124-1, 2-90-2 и 2-90-3. Они образуют плоды с усилием раздавливания, превышающим 5,0 Н, что обеспечивает сохранность целостности и транспортабельность при ручном сборе. По содержанию биологически активных веществ не выявлено комплексных источников повышенного их накопления. Отобраны генотипы с высоким содержанием отдельных биохимических веществ. Наибольшим накоплением растворимых сухих веществ и сахаров отмечены отборы 2-90-3, 18-11-4 и 2-115-1, витамина С - 6-125-4 (59,8 мг/100 г) и 2-90-3 (61,5 мг/100 г). В качестве новых источников в селекции на повышение вкусовых характеристик малины необходимо использовать отборные формы 2-90-2, 2-115-1 и 6-125-4, приближающиеся по вкусу к сорту-эталону Новость Кузьмина. Новыми источниками в селекции малины, объединяющими комплекс хозяйственно ценных признаков на высоком уровне, являются отборные формы 2-90-2, 2-90-3 и 2-115-1.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the research is to search new sources of the main economically valuable traits for further breeding of raspberry. Nineteen previously created selected forms were studied for winter resistance components under controlled conditions, for resistance to major fungal diseases, productivity components, strength and biochemical composition of fruits. The zoned Gusar variety was used as the control. The work was carried out in 2018-2020 according to generally accepted techniques. Artificial freezing of raspberry stems was carried out in the climate chamber TH-6 JEIO TECH. According to the results of the studies, selected forms 8-10х-1, 6-125-4, which have an increased resistance to certain components of winter resistance, have been identified. Hybrids 2-115-1 and 1-188-1 have cumulative resistance to winter damage factors. Based on the integrated resistance of raspberry hybrids to the main fungal diseases, new sources have been revealed: forms 1-124-1, 2-115-1, 2-115-2, 1-111-21, 1-8-2, 2-35-1, 2-90-3, 6-125-4, 3-4-2, 8-10х-1, 4-33-21 and 4-122-2. The degree of their damage did not have a significant influence on winter hardiness, productivity and quality of berries. As the result of study of components of the raspberry productivity, selected forms (1-111-21, 2-90-2 and 2-90-3), forming fruits with an average weight of more than 4.0 g, and genotypes with large and one-dimensional fruits (1-176-21, 2-35-1, 4-33-21, 1-124-1) not growing smaller from picking to picking were identified. The highest potential productivity was noted for selections 2-115-1, 1-111-21, 1-188-1, 4-46-2, 2-90-2 and 2-90-3, capable to form a yield of more than 1.3 kg per bush. The selections 1-124-1, 2-90-2 and 2-90-3 are distinguished by an increased strength of the fruits. They form fruits with a crushing force exceeding 5.0 N, which ensures the safety of integrity and transportability when manually harvested. No complex sources of increased accumulation of biologically active substances have been identified. Genotypes with a high content of individual biochemical substances were selected. The highest accumulation of soluble solids and sugars was noted in the samples 2-90-3, 18-11-4 and 2-115-1. Highest accumulation o the vitamin C was observed in the samples 6-125-4 (59.8 mg/100 g) and 2-90-3 (61.5 mg/100 g). As new sources in breeding to improve the taste characteristics of raspberry, it is necessary to use selected forms 2-90-2, 2-115-1 and 6-125-4, approaching in taste to the standard variety Novost Kuzmina. Selected forms 2-90-2, 2-90-3 and 2-115-1 are new sources in raspberry breeding, combining a complex of economically valuable traits at a high level.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>отборная форма</kwd><kwd>зимостойкость</kwd><kwd>грибные болезни</kwd><kwd>крупноплодность</kwd><kwd>продуктивность</kwd><kwd>прочность плодов</kwd><kwd>биохимический состав</kwd><kwd>вкус</kwd></kwd-group><kwd-group xml:lang="en"><kwd>selected form</kwd><kwd>winter hardiness</kwd><kwd>fungal diseases</kwd><kwd>large-fruited</kwd><kwd>productivity</kwd><kwd>fruit strength</kwd><kwd>biochemical composition</kwd><kwd>taste</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Минобрнауки РФ в рамках Государственного задания ФГБНУ ФНЦ Садоводства (тема №1. 0432-2021-0001).
