Relevance. Currently, there is an increased need to replenish the grape assortment with adaptive, valuable agrobiological and technological properties, competitively capable varieties and clones, the introduction of which into production will ensure an increase in the profitability of the grape-growing industry.Methods. In the ampelographic collection of DSOSViO in 2012–2018, the study of breeding and introduced grape varieties was carried out: table varieties — Bulatovsky, Zhemchuzhina Yuga, Eldar, Suvenir DSOSViO, Yantar Dagestansky, Leki, Kishmish Derbentsky, Zarya Derbenta, Agadai (control), Moldova (control); technical varieties — Fioletta, Slava Derbenta, Saperavi (control). Grape culture is root-related, irrigated, not covered. The shape of the bushes is high-rammed (120 cm), double-shouldered cordon Kazenava. Planting scheme of grape varieties was 3.5 × 2.0 m.Results. Studies have found that grape varieties have high quality and productivity indicators: the fertility coefficient is 1.02–1.57, the yield from the bush is 10.4–16.5 kg. Mechanical composition and chemical properties of bunches and berries in the studied grape varieties: the juice content in the berries is low — Agadai (control); medium — Yantar Dagestansky, Zhemchuzhina Yuga, Leki, Eldar, Souvenir DSOSViO, Moldova; high — Fioletta, Saperavi (control), Slava Derbenta. The attachment of berries to the peduncle is very strong in table grape varieties and Agadai variety (control). Most of the DSOSViO grape varieties proved to be quite resistant to pests and major fungal diseases. The DSOSViO grape varieties exhibit high adaptability in the conditions of the South of Dagestan, which allows to achieve high yields and product quality in the changing climatic conditions of the region. Varieties of the station’s table breeding direction can take a worthy place in the pipeline of fresh grapes intake and consumption in the period July — October, and red varieties of the technical direction are promising for obtaining high-quality terroir wines.

В промышленных насаждениях Республики Дагестан нет сортов технического направления использования, выведенных на основе местных сортов и отвечающих требованиям современного, в т.ч. терруарного виноделия, а также обладающих устойчивостью к неблагоприятным условиям среды, болезням и вредителям. Цель работы - выведение генетически высокопродуктивных сортов винограда различного направления использования, устойчивых к грибным болезням и корневой форме филлоксеры, для возделывания в почвенно-климатических условиях юга России. В условиях Дагестана высокую адаптивность и урожайность проявляет сорт Первенец Магарача, который широко привлекается в селекционную программу скрещиваний станции как донор устойчивости. Исследования проводились на Ампелографической коллекции ДСОСВиО в 2013-2018 гг. В статье приводится агробиологическая и хозяйственно-технологическая оценка элитных сеянцев новой селекции, выведенных путем гибридизации аборигенных сортов и сорта Первенец Магарача как донора устойчивости к биотическим и абиотическим стрессорам. Выделенные элитные формы отличаются высокими показателями качества, биологической выносливостью в гибридном питомнике на сильном инфекционном фоне по филлоксере и болезням грибной этиологии. Использование сорта Первенец Магарача в селекции новых сортов с привлечением дагестанских аборигенных сортов позволяет получать генотипы с высокой устойчивостью к болезням и вредителям винограда в условиях Дагестана. Industrial plantations of Republic of Dagestan lack wine varieties breeded from local cultivars and meeting the requirements of modern, including terroir, winemaking, and resistant to adverse environmental conditions, diseases and pests. The purpose of this work is to develop genetically highly productive grape varieties resistant to fungal diseases and the root form of phylloxera for cultivation in the soil and climatic conditions of the South of Russia. In the conditions of Dagestan ‘Pervenets Magaracha’ grape variety shows high adaptability and productivity, and is widely involved in the breeding program of crossings of the Station as a donor of stability. Research was conducted on the Ampelographic collection of the Station in 2013-2018. The article presents agrobiological and economic-technological assessment of elite seedlings of new selection, bred by hybridization of local varieties and ‘Pervenets Magaracha’ variety as a donor of resistance to biotic and abiotic stressors. The selected elite forms are characterized with high quality parameters, biological strength in a hybrid nursery with a strong infectious background for phylloxera and fungal diseases. The use of ‘Pervenets Magaracha’ variety in the selection of new varieties, involving Dagestani local varieties, allows us to obtain genotypes with high resistance to grape diseases and pests in the conditions of Dagestan.
