NOVATEUR PUBLICATIONS JournalNX- A Multidisciplinary Peer Reviewed Journal ISSN No: 2581 - 4230 VOLUME 7, ISSUE 5, May. -2021 th Republic of Uzbekistan in 2017-2021” dated RESULTS AND DISCUSSION: February 7, 2017 and in relevant normative- According to the study, the beginning of legal documents, the research aimed at the growing season of raspberry cultivars was selecting varieties that meet all the observed on March 12 in the Progress (st) requirements of modern horticulture is of great cultivar, while in Vislukha (March 10) and importance. Vladimir (March 6) cultivars it was 2-6 days The healing properties of raspberries earlier. In Malboro (March 14), Barnaulskaya are known since ancient times. Its tincture (March 14) and Gigant (March 16) varieties, it from dried flowers was used as remedy when started 2-4 days later than the standard bitten by snakes and scorpions. The variety. harmonious combination of sugars, organic When the flowering period of the acids, vitamins C, P, В9 and hematogenous studied raspberry cultivars, in Progress (st) compounds in its content makes raspberry cultivar it started on April 3 and ended on May very useful in various diseases such as ulcers, 16, while only Vislukha (April 1) variety started anemia, impaired vascular permeability. to flower 2 days earlier than the standard Raspberries are rich in antibiotics that variety and ended on May 13. Among the have antiseptic effect on the upper respiratory cultivars, Malboro (April 12), Vladimir (April tract and prevent colds. The fruit contains 5- 11) cultivars were observed to flower 8-9 days 10% of sugar, 0.5 to 2.5% of organic acids, later than the standard variety, while the end of vitamins В1, В2, В6, В9, В12, С, D, Е, РР, Р, К, flowering was noted in Malboro cultivar on additives, dyes ( up to 1.5%), phosphorus, iron, May19, in Vladimir cultivar on May 10. From salts, pectin (0.5-0.9%) [1,4,6]. the studied cultivars, Gigant (May 1) and Fresh raspberry fruit is used in the preparation Barnaulskaya (May 6) cultivars had the latest of jams, juices, jelly, compotes, syrups, etc. flowering stage, that is 28-33 days later than the standard variety, while the end of flowering MATERIALS AND METHODS: was observed in Gigant cultivar on May 30, in The research is being conducted at the Barnaulskaya cultivar on June 6. The duration Andijan research and experimental station of of flowering stage varied from 29 days (Gigant) the Research Institute of Horticulture, to 43 days (Progress (st)). Viticulture and Wine-making named after When the ripening period of fruit of Academician Makhmud Mirzaev. raspberry cultivars was observed, it began on The object of study is the following May 30 in Progress (st) and ended on July 3, cultivars belonging to different ecological while only in Vislukha (May 29) cultivar it groups: "Progress (Russia)", "Malboro (USA)", occurred 1 day earlier than the standard "Vislukha (Russia)", "Barnaulskaya (Russia)", variety, the end of maturation was observed on "Vladimir (Russia)", "Giant (Russia)". June 29 in this cultivar. Among the studied Research on the evaluation of raspberry cultivars, the fruit ripening stage began too late cultivars was conducted on the basis of in Gigant (June 22) and Barnaulskaya (June 28) "Methods and programs for the study of cutivars, that is 23-29 days later than in varieties of fruits, berries and nuts" (Orel standard variety, the end of fruit maturation 1999). Mathematical and statistical processing was noted in Gigant cultivar on July 20, in of research data was performed using Barnaulskaya cultivar on Microsoft Excel according to the method recommended by B.A. Dospekhov (1985) [3,5]. 41 | P a g e
