Abstract
Local grapevine cultivars of Crimea are of interest for modern breeding and production as genotypes with a
number of valuable economic characteristics. The study of biological properties of these cultivars is relevant for identification and using sources of valuable traits. The purpose of the work is to study the indicators of productivity and quality of grapes of Crimean local grapevine cultivars and to identify sources of valuable traits maximum adapted to the conditions and needs of the Republic of Crimea. The place of research is the Basic Collection of Grapes of the FSBSI Institute Magarach of the RAS. The object of research is 72 local grapevine cultivars of Crimea. The research used standard methods of varietal study. As an assessment result of local grapevine cultivars of Crimea in 2019–2021, in terms of productivity and quality of grapes, the
sources of valuable for breeding economic traits were identified: wine cultivars ‘Abla Aganyn Izium’, ‘Tergulmek’, ‘Kapitan Yani Kara’, ‘Khersonesskiy’, ‘Kokur Belyi clone 46-10-3’, ‘Kokur Belyi clone 46-10-6’; table-wine cultivars ‘Emir Weiss’, ‘Solnechnaya Dolina 58’, ‘Tashly’; table grapes ‘Adgem Misket’, ‘Alburla’, ‘Manzhil Al’ and ‘Tanagoz’. In terms of cropping capacity, grape quality and resistance to stress factors in 2021, the quantity of 35 local cultivars of Crimean grapes of the Magarach Ampelographic Collection (AC) have been identified and included in the State Register of Breeding Achievements approved for usage: ‘Abla Aganyn Izium’, ‘Adgem Misket’, ‘Aibatly’, ‘Akseit Kara’, ‘Amet Agi Ibram’, ‘Artin Zerva’, ‘Biyas Aibatly’, ‘Bogos Zerva’, ‘Dardagan’, ‘Kandavasta’, ‘Kirmizi Sap Sudakskiy’, ‘Kok Habakh’, ‘Kokur Belyi Polurassechennyi’, ‘Kokurdes Belyi’, ‘Kurtseit Aganyn Izium’, ‘Kutlakskiy Chernyi’, ‘Misgiuli Kara’, ‘Misket’, ‘Murza Izium’, ‘Muscat Krymskiy’,
‘Nasurla’, ‘Sale Aganyn Kara’, ‘Saſta Durmaz’, ‘Solnechnaya Dolina 16’, ‘Solnechnaya Dolina 58’, ‘Sykh Dane’, ‘Tanagoz’, ‘Tashly’, ‘Tergulmek’, ‘Khalil Izium’, ‘Khachador’, ‘Chernyi Krymskiy’, ‘Shira Izium’, ‘Emir Weiss’ and ‘Yanykh Zerva’. The results obtained contribute to the efficient use of grape genetic resources in scientific research.
