The article presents the results of studies of the chemical composition, commercial qualities and taste of berries of promising strawberry varieties breeding of the All-Russian Horticultural Institute for Breeding, Agrotechnology and Nursery (Moscow) in the conditions of the Orenburg Urals. The studies were carried out in 2016-2018 on the basis of the Orenburg Experimental Station of Horticulture and Viticulture of the All-Russian Horticultural Institute for Breeding, Agrotechnology and Nursery in specific conditions, where almost annually dry and moderately dry climatic periods were observed during the formation of the yield (May-June). A comparative evaluation of varieties on the content of sugars, acids, vitamin C in berries, taste and attractiveness of appearance is given. The dependence of the studied parameters on the genotype of the variety and vegetation conditions was established. Depending on the variety and year, the content of soluble solids varied from 7.2 to 10.2 %, with an average content of 8.9 %; total acidity varied from 0.8 to 1.2 %, with an average content of 1.0 %; the content of ascorbic acid (vitamin C) was from 45.1 to 78.5 mg/100 g, with an average content of 56.4 mg/100 g. Varieties with high parameters of tasting evaluation (Darenka, Kokinskaya Zarya, Studencheskaya), soluble solids (Rosinka, Studencheskaya) and ascorbic acid (Kokinskaya Zarya, Bereginya) were revealed. They are recommended to be grown to obtain fresh consumption products and as processing products of various directions. Bereginya, Darenka and Rosinka varieties surpass control varieties in certain biochemical parameters and can be used in breeding in the Urals region to obtain new genotypes with an increased content of a specific biologically active substance. The variety Tsaritsa is selected for high commodity qualities of berries (weight, dessert taste, attractiveness of appearance) and is recommended for commercial production of berries and involvement in breeding process. It has been established that the taste of berries is determined by a complex of acids, sugars and aromatic substances. This parameter was greatly influenced by weather conditions, from which air temperature and precipitations were determining.

Active Substances

Grapes is a highly valuable food product due to the presence in it of a number of biologically active substances, among which vitamins occupy a special place. One of the most important and studied in grapes is vitamin C (ascorbic acid). The ascorbic acid contained in plant tissue participates in redox metabolism, thereby increasing the resistance of plant organisms to infections and low negative temperatures. Studies aimed at determining the concentration of vitamin C in plant material are important both for breeding and for identifying the most sustainable competitive varieties. The purpose of these studies is to study the content of vitamin C in grapes cultivated in the South of Western Siberia. Conducted research with 12 introduced varieties and selected forms growing in the collection of the Research Institute of horticulture of Siberia M.A. Lisavenko, allowed to establish dependence of accumulation of ascorbic acid in berries on weather conditions; to allocate 5 genotypes with high content of vitamin C. It is noted that the ripening period of berries, their color, as well as the direction of use and ecological and geographical origin of varieties and selected forms did not affect the accumulation of vitamin C in the period 2014–2016.

High nutritional significance of separate decorative species is demonstrated. A. caeruleum is shown to be a leader in the accumulation of ascorbic acid (more than 9000 mg/100 g d.w.) and polyphenols (more than 8000 mg GAE/kg d.v.). Detected ascorbic acid concentration range for 8 studies Allium species was 568 (A. ramosum) – 9980 (A. caerulum) mg/100 g d.w.; polyphenols 1392 (A. obliquum) – 8582 (A. caerulum) mg GAE/kg d.w.; water-soluble compounds 28 (A. aflatunense, A. obliguum) – 69 (A. ramosum) mg/kg d.w.; chlorophyll 0.54 (A.oreophilum) – 1.69 (A. ursinum) mg/100 g d.w.; carotene 0.07 (A. oreophilum) – 0.25 (A.ursinum) mg/100 g d.w.; selenium 72 (A. ursinum) – 245 μg/kg d.w., (A. ramosum). Adequate consumption level of vitamin C may be provides by 6.2 g of A.caerulum leaves. Antioxidant activity of Allium species alcoholic extracts composed a range from 1.5 (A. obliquum) to 6.4 (A. ursinum) mg GAE/g d.w. A. ramosum and A. oreophilum demonstrated the highest content of total soluble solids. The highest content of photosynthetic pigments happened to be typical for A. ursinum. The ratio between antioxidant activity of alcoholic and water extracts of Allium leaves was in the range between 0.89 and 2.21 depending on plant species: the highest value was registered in leaves of A. ursinum, the lowest – in leaves of A. ramosum. In a whole the highest content of antioxidants was demonstrated for leaves of A. caerulum. The highest levels of photosynthetic pigments and antioxidant activity of alcoholic extracts were indicated in leaves of A. ursinum.

Therapeutic Value

The aonla (Emblica officinalis Gaertn.) is commonly referred to as a "Miracle Fruit for the Health", owing to the high nutritious and therapeutic value of its fruits. But the fresh fruits are not ingested freely due to the astringent taste caused by fruit tannins. In production and acreage under aonla cultivation Uttar Pradesh is the leading state in the country. The study aims to understand the storage behaviour of the pickle prepared from the aonla fruit. Pickle was prepared from the eight aonla cultivars viz - Kanchan, Banarasi, Krishna, Chakaiya, NA – 8, NA – 7, NA – 6, and NA – 9. Physicochemical characters (such vitamin 'C' (ascorbic acid), total soluble solids (T.S.S.), browning, and acidity), and sensory/organoleptic scores were recorded at the monthly interval during storage. The result showed that the aonla pickle is acceptable up to nine months thereafter, reduction was noted in the physicochemical and organoleptic scores. Among all cultivars tested, NA-7 was found to be ideal for pickle preparation.

The aim of this work was to investigate and compare the amounts of biologically active compounds, dry matter and soluble solids in pulp and peels of four pear cultivars (‘Ksena’, ‘Beloruskaja pozdniaja’, ‘Alna’ and ‘Aleksandr Lucas’). The research was carried out at Vytautas Magnus University Agriculture Academy (Lithuania) in 2020. Four pear cultivars (‘Ksena’, ‘Beloruskaja pozdniaja’, ‘Alna’ and ‘Aleksandr Lucas’) were cultivated at a farm in the Joniškis District of Lithuania. Pears were grown following traditional pear production technology. The amounts of dry matter, soluble solids, vitamin C and fiber were determined using the standard method. The total content of phenolic compounds was determined using a Folin-Ciocalteu reagent with a UV/VIS spectrophotometer. The research results showed that significantly the highest amounts of soluble solids were found in the ‘Alna’ pear fruit pulp (14.25% f. w.). The ‘Alna’ peel sample had significantly the highest amount of total phenolic compounds (1290.99 mg 100 g–1 d. w.). The highest content of dry matter was found in the ‘Aleksandr Lucas’ pear fruit peel (24.67%). The ‘Aleksandr Lucas’ and ‘Beloruskaja pozdniaja’ pear fruit peel contained significantly the highest amounts of vitamin C (2.70 and 2.63 mg 100 g–1 f. w., respectively). The highest content of fiber was found in the ‘Ksena’ fruit peel (36.12% d. w.). The investigated pear peel sample had significantly higher amounts of dry matter, vitamin C, total phenolic compounds and fiber than the pulp. However, the pulp contains the highest contents of soluble solids.

The fruit physical and chemical characteristics can vary during the maturation period and this variation depends, among other factors, on the weather conditions during fruit development. This study aimed to evaluate the changes in physical and chemical characteristics of eight peach cultivars during two seasons. The cultivars Campinas 1, Coral, Maciel, Marli, Premier, Regis, Rei da Conserva and Tropic Beauty were planted on Okinawa rootstock at the experimental orchard of the Federal University of Viçosa (UFV), Viçosa-MG, Brazil, in 2008 and the following characteristics were evaluated: fruit weight, skin color, firmness, soluble solids, titratable acidity, ascorbic acid and total carotenoids. The experiment was conducted during 2011 and 2012 growing seasons in a completely randomized design with eight treatments (cultivars), three repetitions and 10 fruits per plot. There were differences between the variables for the two seasons, with the largest variations observed for firmness, ascorbic acid and total carotenoids. Cultivars Maciel and Marli produced fruit with higher mass, Tropic Beauty with greater firmness and Rei da Conserva, Coral and Marli with higher soluble solids contents. The cultivar Rei da Conserva presented higher values for most of the evaluated variables in both seasons. The yellow color, evaluated by the hue angle, is associated with total carotenoids content in peaches.

The chemical composition of 30 mango varieties from the Fortuna Substation in the Southern Region of Puerto Rico was studied. The proportion of peel, pulp, and seed, as well as the moisture content, total and soluble solids, ascorbic acid, total and reducing sugars, pH, total titrable acidity, and ß-carotene were determined for each variety. Of these varieties, the Edward gave the highest pulp yield; and the Julie and the Francisque had the highest vitamin C values, providing the MDR with 200 g. of pulp. The Carrie, Palmer, Paheri, Adams, Zill, Edward, and Sensation surpassed the MDR of 5,000 I.U. for vitamin A, with the Carrie showing the highest with 7,9001. U. per 100 g. of pulp. Six of these varieties were again analyzed the following year. The resulting differences between the same varieties in the 2 years that they were analyzed could be attributed to an error in the visual evaluation of the degree of ripeness of the fruit at harvesttime.

To conduct research in 2016 - 2018 at the L.P. Symyrenko experimental station IS NAAN the following varieties of cherry fruits were selected: Alpha, Zhadan, Chance, Elegant, Artemenko Memory, Optimist, Podbelskaya. The cherry was harvested in the consumer stage of ripeness during the first decade of July. According to the complex of physicochemical and organoleptic parameters, the selection of the best variety of cherry fruits was performed by the method of multicriteria optimization. The aim of the work was, on the basis of a comparative analysis of a set of physicochemical and organoleptic indicators of cherry fruits, using multicriteria optimization, to determine the best varieties recommended for production. The results of studies showed that the weight of cherry fruits ranged from 4,2 to 5,2 g. The content of soluble solids in cherry fruits was at the level of 15,26–15,89% and was predominant for cherries in Artemenko memory and the lowest in Podbelska variety. The sugar content of cherry fruits was 10,14 −10,96%. The level of titratable acids that determine the taste of cherry fruits together with the gourds is in the range from 1,67 to 2,02%. It is the highest for cherry fruits of the Artemenko memory, and the lowest for the Elegant variety. The cherry fruits of the experimental varieties have a significant content of ascorbic acid − 19,15−16,25 mg/100 g. The cherries of the Artemenko memory, and the lowest of the Optimist variety, prevail in the fruits. The tasting rating of cherry fruits is 8−8,7 points. According to the complex of the mentioned above physicochemical and organoleptic indicators by the method of multicriteria optimization such varieties of cherry fruits as Artemenko Memory, Alpha and Zhadana are recommended for production implementation
