Suitability of fruits of selected blackcurrant (Ribes nigrum L.) cultivars for fresh market
Journal of Berry Research, 2012
The fruit quality of 10 blackcurrant genotypes of Polish origin ('Bona', 'Gofert', 'Tines', D13B/11 and PC-425 very recently named as 'Tihope') and Ukrainian ('Chereshnieva', 'Yubylejnaia Kopania', 'Saniuta', 'Sofievskaia' and 'Vernisazh') was evaluated in Central Poland in 2008-2010. The yield, fruit size (weight of 100 berries), the length of strigs and number of berries per strig, fruit firmness, soluble solids, content of ascorbic acids (vit. C), fruit appearance, taste and aroma as well as the shelf-life of fresh fruit in a room temperature were assessed. Results obtained in studies showed that new Polish cultivars 'Tihope' (PC-425) and 'Gofert' as well as Ukrainian cultivars 'Jubilejnaja Kopania' and 'Vernisazh' were the most productive and had the highest average fruit yield. The largest fruits produced the Polish breeding clone (D13B/11). Large fruits also had the standard cultivar 'Bona', cv. 'Tihope' (PC-425) and 'Saniuta'. The highest number of fruit per strig was counted on Ukrainian cultivars ('Chereshnieva', 'Yubylejnaia Kopania', 'Saniuta') and Polish cv. 'Gofert'. These cultivars also produced the longest strigs. The tested cultivars differed slightly in the attractiveness of the fruits. 'Bona' and 'Tihope' (PC-425) boasted the best appearance of fruits. Fruits of 'Bona' were found as the most flavorful. 'Saniuta', 'Gofert' and D13B/11 demonstrated only a little less taste and aroma. The best shelf-life of fruits possessed 'Bona', 'Tihope' (PC-425) and 'Tines'. The firmest fruits were produced by 'Chereshnieva', 'Tihope' (PC-425), 'Sofievskaia' and 'Gofert'. The highest content of soluble solids was found in fruit of 'Gofert' and 'Tines'. The richest in vitamin C were fruits of 'Gofert', 'Sofievskaia' and 'Tihope' (PC-425).

The aim of the investigation was to evaluate the effect of genotype and growing conditions on blackcurrant fruit weight and biochemical composition. The trial was carried out during the years 2011 and 2012 in South Estonia with two cultivation methods (conventional and organic) and eight genotypes of different genetic background, including two Scottish, ‘Ben Alder’ and ‘Ben Lomond’; two Swedish ‘Intercontinental’ and ‘Titania’; a Belarusian ‘Pamyati Vavilova’, and three recently selected genotypes from the Estonian blackcurrant breeding programme, ‘Karri’, ‘Asker’, and ‘Mairi’. From each genotype and in both cultivation sites 500 g of fruit at full maturity was collected in three replications. Fruit weight, soluble solids (SS), sugars, organic acids, sugar/acid ratio, and ascorbic acid (AsA) concentrations were determined. Fruits from the organic cultivation site were smaller and contained more SS and sugars, they also had a higher sugar/acid ratio than conventionally grown berries....

The study was conducted in the years from 2011 to 2013 at the Research Institute of Horticulture in Skierniewice, Poland. The aim of the research was to assess the breeding value, based on the effects of general and specific combining abilities (GCA and SCA), of 15 parental genotypes of blackcurrant in terms of fruit yield and quality. The plant material consisted of F1 generation seedlings obtained by crossing, in a factorial mating design of twelve maternal (‘Bona’, ‘Big Ben’, ‘Chereshnieva’, Kupoliniai’, ‘Gofert’, ‘Tines’, ‘Sofievskaia’, ‘Tihope’, ‘Ores’, ‘Ruben’, ‘Titania’ and D13B/11) and three paternal cultivars (‘Ceres’, ‘Foxendown’ and ‘Saniuta’). It was found that the cultivars ‘Ruben’, ‘Big Ben’, ‘Gofert’ and D13B/11 had significant positive effects of GCA on fruit yield at least in two consecutive years. ‘Ruben’, ‘Saniuta’ and D13B/11 had positive GCA effects on fruit weight. For ‘Chereshnieva’, ‘Gofert’, ‘Tines’, ‘Sofievskaia’, ‘Tihope’, ‘Titania’, ‘Ceres’ and Saniuta’ p...
European Network for Blackcurrant (Ribes Nigrum L.) Cultivar Evaluation
Acta Horticulturae, 2012
According the COST 863 Action-"Euroberry research: from genomic to sustainable production, quality and health" a European network for blackcurrant (Ribes nigrum L.) cultivar evaluation was organized. Lithuania, Latvia, Estonia, Norway, Denmark and Romania have participated in this Network. The objective of studies was to investigate the influence of geographic and climatic conditions on plant performance, berry quality and resistance to pest and diseases. A common protocol for evaluation and descriptors for blackcurrants were developed. Plant maintenance and cultivation was performed according to the local technologies and requirements of each partner (country). Phenological, morphological, productivity, berry quality and plant resistance to pest and disease characteristics were evaluated in the period 2005-2009.
Characterization of Ribes Nigrum in Relation to Fruit Maturity and Genotype
II International Organic Fruit Symposium, 2013
Black currant (Ribes nigrum L.) production on Prince Edward Island, Canada is a new industry, requiring a baseline evaluation of berry quality and the factors that affect it. The overall goal of this research was to determine the influences of fruit maturity (harvest timing) and cultivar on berry quality. The quality characteristics of interest in this research were berry size, juice pH, titratable acidity (TA), total soluble solids (TSS), and total antioxidant capacity. In a harvest timing trial, quality of 'Titania' black currant berries was measured at 3, 6, 10 and 18 days after 95% of the berries turned black at two farms. In a cultivar trial, berry quality of seven cultivars ('Titania', 'Ben Alder', 'Ben Connan', 'Ben Sarek', 'Ben Tirran', 'Blackhome' and 'Whistler') was determined at 6 and 10 days after 95% of the berries turned black. In the timing trial, berry size unexpectedly decreased with time, most likely due to early berry splitting and drop associated with atypically warm and wet weather. Total antioxidant capacity increased with time, while there were marginally significant increases in TSS. Berry firmness was not measured, but was observed to decrease with time. There was a significant cultivar effect on berry size and TSS, and a significant timing × cultivar effect on TA. 'Whistler' berries had the largest size, highest TSS and lowest TA, compared with the other cultivars. Further analysis of the berry quality characteristics (including flavour) and timing of harvest effects are needed to verify the most appropriate management options for PEI producers.
Factors influencing quantities of sugars and organic acids in blackcurrant concentrates
Zeitschrift f�r Lebensmitteluntersuchung und -Forschung A, 1998
of endogenous non-volatile flavour components, i. e. sugars and organic acids, in fruit juice products is desirable. A study of 133 blackcurrant concentrates from three seasons examined variation in sugars and acids arising from storage of fruit at freezing or sub-ambient temperature, seasonal differences, geographical origin and choice of conventional thermal-evaporative or freeze concentration technology. Compared with freeze concentrates, conventional concentrates had significantly higher contents of total sugars and acids, notably malic acid, and higher fructose/ glucose, lower malic/citric acid and similar sugar/acid ratios. Concentrates from frozen fruit generally had smaller amounts of fructose, total sugars and fructose/glucose ratios than those from fresh fruit, as well as less citric, ascorbic and total acids and lower sugar/acid ratios. Principal component analysis of 40 randomly chosen concentrates showed that variance is dominated by differences in fructose, total sugars and ascorbic acid contents and sugar/acid ratios. Geographical origin and concentration technology were major sources of variance but changes in post-production sub-ambient storage could not be excluded.
Quality changes in black currant berries during ripening
Black currant 'Pilėnai', 'Vyčiai', 'Kriviai' and 'Gagatai' berries of different stages of maturity were studied at the Lithuanian Institute of Horticulture. At technical maturity, black currant 'Pilėnai' and 'Vyčiai' berries were distinguished for having the greatest masses: 1.54 g and 1.48 g, respectively. When berries overripened, their mass decreased from between 2.9 % ('Kriviai') to as much as 38.3 % ('Gagatai'). During berry ripening, the skin of black currants decreases in firmness. Overripe berries of cvs. 'Pilėnai' and 'Vyčiai' softened the most: 3.8 times and 3.4 times, respectively. At technical maturity, berries of cvs. 'Pilėnai' and 'Kriviai' were distinguished for having the most firm skin: 63.09 N cm-2 and 53.9 N cm-2 , respectively. The highest levels of ascorbic acid were found in berries at the beginning of ripening. Overripe berries had the lowest levels of ascorbic acid. Among various cultivars, 'Pilėnai' and 'Gagatai' berries of differing maturity had the highest levels of ascorbic acid, 152-114 mg 100 g-1 and 147-103 mg 100 g-1 , respectively. With the exception of berries of cvs. 'Vyčiai' and 'Pilėnai', larger amounts of pigments accumulated in overripe berries. Among all cultivars, mature and overripe berries of cvs. 'Kriviai' and 'Gagatai' had the highest levels of anthocyanins, at 387.61-450.63 mg 100 g-1 and 349.79-393.91 mg 100 g-1 , respectively. The greatest amounts of dry soluble solids were found in overripe berries. The highest levels were present in the mature and overripe berries of cv. 'Kriviai' (14.55-16.95 %). The amount of titratable acidity in black currant berries decreased during ripening. Significantly greater amounts of acids were found in 'Pilėnai' berries of various stages of maturity (3.27-2.41 %).
Fruit Growing Research
Blackberries are an important commercial fruit crop, widely grown. The blackberries contain significant amounts of polyphenol antioxidants such as anthocyanin pigments linked to potential health protection against several human diseases, so the demand is increasing. In order to identify the most suitable varieties for the Vlasia Plain area, in 2020 an experimental plot with 6 stable accessions was established. The cv. ‘Chester’, ‘Dar 8’, ‘Navaho’,‘Polar’, ‘Thornfree’, ‘Triple Crown’, were planted in a plantation scheme 3.0 m × 1.0 m. For each variety, during 2021, ripened fruits were harvested and biometric determinations have been done in the laboratory, being measured fruit weight and diameter, firmness, titratable acidity and pH, all fruit quality indicators. The preliminary results showed that blackberry varieties without thorns are larger than thorny varieties and more suitable for fresh fruit consumption, while the ‘Dar 8’ fruit are not so fragrant, their pulp is stronger, so ...
Foods
Black fruits, especially blackberries and black currants, are highly appreciated by consumers due to their nutraceutical properties, which have reported health benefits. This study aimed to assess the fruit quality of the blackberry (cv. ‘Čačanska Bestrna’) and black currant (cv. ‘Čačanska Crna’) created at the Fruit Research Institute, Čačak (Republic of Serbia) by evaluating basic quality parameters (fruit weight, soluble solids), and content of primary (sugars and organic acids) and secondary (phenolic compounds) metabolites. Additionally, the study examined the quality of frozen and long-term frozen storage (6, 9, and 12 months). The results showed that ‘Čačanska Crna’ contained a high level of total soluble solids (15.23°Bx), sugars (93.06 mg g−1), and a high index of sweetness (159.48) as well as a high content of acids (34.35 mg g−1) in the fruit. Both species were found to contain forty-seven phenolic compounds, including phenolic acids, flavanols, and anthocyanins, analyzed...
