Conveyor of tangerine varieties for the Republic of Abkhazia

Abstract

The paper offers the results of tangerine varieties studying in the Republic of Abkhazia. Research was conducted in 2012-2015 in the territory of experimental sites of Research Institute of Agricul-ture (Abkhazian Academy of Science). Objects of research were 31 accessions of tangerine from the collection of citrus plants. The clones Apsny (25. 09), and Olympiyskiy 2014 (26. 04), the varieties Sentjabr’skiy (29.09), Slava Vavilova (02.10), Sukhumskiy sverhranniy (3. 10) are characterized by the earliest maturing of fruits; Citrus unshiu (typical form) (19. 11) and the variety Iveriya (2. 11) are characterized by the latest maturing of fruits. The longest period of fruits maturing is noted for Citrus unshiu (25 days) and the shortest period of fruits maturing is noted at the varieties Sukhumskiy sverhranniy (13 days) and Slava Vavilova (15 days). A conveyor of tangerine varieties of 14 forms including such as Citrus unshiu, Sochinskiy-23, Iveriya, Chernomorskiy, Kokhorskiy,Jubileyny, Abkhazskiy ranniy, Miyagawa Wase, Kowano-Wase, Sukhumskiy sverhranniy, Slava Vavilova, Sentjabr’skiy, as well as the clones Olympiyskiy 2014, and Apsny is offered. The varieties included in the conveyor are distributed on 4 groups: varieties with the latest maturing term, with medium maturing term, early varieties and new forms of extra-early maturing term. The listed varieties are characterized by medium and large fruits sizes, high productivity and allow to obtain fresh fruits from the third ten-day event of September till the middle of December. Data on biochemical composition of fruits are provided: solid basis, acidum ascorbinicum, titrable acids, sugars and glucoacetometric coeffi cient. The varieties Kowano-Wase, Sukhumskiy sverhranniy, Jubileyny and clones Olympiyskiy 2014 and Apsny were revealed according to the totality of quantitative and biochemical characteristics of fruits.
