Sweet Cherry Cultivars

The research concerning the improvement of the cherry assortment, the cultivars’ quality and the avoiding of market crowding with fresh cherries only on a short term are extremely important objectives for cherries’ breeding. To accomplish some of these objectives, during 1981-2017, hybridization and selection of hybrids were performed at the Research Station for Fruit Growing Iași (RSFG Iași), in the N-E part of Romania, concluding with a series of promising hybrid selections. They have been grafted, planted and studied in trial fields. Therefore, during 1994-2016, RSFG Iași released 28 sweet cherry cultivars with high quality fruits and different maturation stages. In the studies performed during 2014-2017, there were analysed three new sweet cherry cultivars (‘Elaiaşi’, ‘Muşatini’ and ‘Croma’), obtained through controlled hybridization. The comparison of these new cultivars was performed against ‘Van’, used as control, this being a well-known cultivar in the orchards from the study area. Observations and measurements concerning the main phenological stages, natural fertility, physical features, organoleptic, quality and chemical traits of fruit were registered. The cultivars with the biggest dimensions of the fruits were ‘Elaiaşi’ and ‘Croma’ (with a weight between 8.9 and 9.4 g and a fruits’ diameter between 25.2 and 26.6 mm), having significantly larger dimensions in comparison with ‘Van’. In the new investigated cherry cultivars, the values of soluble solids content were comprised between 17.0 and 20.2 °Brix, titratable acidity was between 0.46 - 0.57 mg of malic acid 100 mL-1 juice and the total polyphenols content was recorded between 382.87 - 780.25 mg GAE 100 mL-1 of fresh juice.   ********* In press - Online First.

Abstract The studies were performed for four consecutive years (2016–2019) at the Fruit Growing Research Station (North-East part of Romania), using eleven sweet cherry genotypes as research material. Five of them are new cherry cultivars – ‘Cătălina’, ‘Andreiaş’, ‘Maria’, ‘George’, and ‘Margonia’ – obtained by means of controlled hybridization or open pollination, and six of them are their progenitors (‘Van’, ‘Boambe de Cotnari’, ‘Stella’, ‘Fromm’, ‘Ciliegia di Ottobre’, and the ‘HC 27/4’ hybrid). The experiment compared the traits of new cultivars with those of their progenitors. The following traits were evaluated: tree vigor, frost damage, the phenological stages, and the physical and chemical traits of the fruit. The highest values concerning the fruit's weight have been recorded for ‘Andreiaş’ (10.0 g) and ‘Maria’ (7.6 g), the content of soluble substance was between 16.6 and 19.5°Brix, the titratable acidity was between 0.413 and 0.675 mg malic acid·100 mL−1 juice, and the total content of polyphenols was recorded with values between 268.00 and 488.75 mg GAE·100 mL−1 of fresh juice. The new cultivars have mostly superior traits, especially frost damages, productivity, fruit quality, and fruit's cracking percentage compared with their parental genotypes.

Abstract The study was conducted to determine the effects of Myrobalan rootstock and Blackthorn interstock on fruit physical and chemical traits of five apricot cultivars. The results showed that cultivars grafted on Myrobalan rootstock appear to induce a higher fruit mass when compared with the Blackthorn interstock. Blackthorn interstock showed a tendency to induce a higher soluble solids/titratable acidity ratio than Myrobalan. Values of soluble solids content, total sugars, titratable acidity and fruit firmness between Myrobalan rootstock and Blackthorn interstock were not significant. Regarding cultivars, the greatest fruit mass observed in Roxana in both treatments, and the lowest in Biljana on Myrobalan and in Vera on Blackthorn. The lowest soluble solids, total sugars and soluble solids/titratable acidity ratio were found in Roxana in both variants of grafting, whereas the greatest titratable acidity also observed in Roxana in both cases, respectively. Based on the results from this study, the fruits of Roxana can be recommended for fresh consumption, whereas fruits of the other cultivars can be recommended for processing.

Sweet Cherry Cultivars

Banjaluka region is characterized by a very rich diversity of old and autochthonous sweet cherry cultivars, which represent a very important genetic potential for future breeding programs. Autochthonous sweet cherry cultivars are spontaneously propagated and used in very few areas for production and consumption in the fresh condition. A very small percentage of autochthonous cultivars are used in local markets or in some forms of processing. The main reason for this is the small number of individual trees whose fruits are used for own household and their poor management. In order to popularize the production and sale of autochthonous sweet cherry cultivars, during this research was perform the basic pomological measurements of the five most common autochthonous sweet cherry cultivars in the Banjaluka region (Ašlamka, Banjalučka crnica, Bjelica-Biljur, Cipov and Crveni hrušt). Pomological (the weight and dimensions of the fruit, weight and dimensions of the pit, dimension of the stalk and the firmness of the fruit flesh) and chemical (total soluble solids content of the fruit) fruit characteristics were determined. Results showed differences in investigated parameters between the cultivars.

Sweet Cherry Cultivars

Starting with 1981, the objectives of the breeding programmes in the Research Station for Fruit Growing (RSFG) Iaşi, Romania, took into consideration the on-going improvement of the sweet cherry assortment with cultivars having fruit-bearing precocity, with great productions, self-fertile, with decreased trees’ vigour, crown compactness, resistant to anthracnose, monilia, frost and fruit’s cracking, flowering lateness, superior quality of the fruits and ripening time at the extremities of the sweet cherries’ maturation season. As a result of the breeding programmes that took place up till present at RSFG Iaşi, 28 new sweet cherry cultivars, obtained through controlled hybridization, free pollination and conservative clonal selection, were homologated during 1994-2017. The present results refer to a study led during 2015-2017, having as biological material nine sweet cherry cultivars (‘Cetăţuia’, ‘Cătălina’, ‘Golia’, ‘Bucium’, ‘Ştefan’, ‘Iaşirom’, ‘Oana’, ‘Radu’ and ‘Ludovan’) obtained through controlled hybridization. The comparision of the cultivars has been performed versus their genitors ‘Van’ (♀) and ‘Boambe de Cotnari’(♂). There have been taken observations and determinations concerning the trees’ vigour, resistance to frost and anthracnosis, the main growing and fructification phenophases, physical and chemical treats of the fruit. The highest values regarding fruit’s weight (7.5-8.9 g) have been recorded for the ‘Ludovan’, ‘Bucium’, ‘Ştefan’, ‘Iaşirom’ and ‘Golia’ cultivars, while the values of the soluble substance content have been between 15.20-19.25 °Brix, the titratable acidity has been between 0.455-0.764 g malic acid 100 mL-1 of fresh juice and the total content of polyphenols has recorded values between 97.41-574.95 mg GAE 100 mL-1 of fresh juice. The hybridization between ‘Van’ and ‘Boambe de Cotnari’ has allowed the obtaining of valuable cultivars, that got remarked by earliness (‘Cetăţuia’, ‘Cătălina’), decreased trees’ vigour (‘Ştefan’, ‘Golia’), particular quality of the fruits (‘Ludovan’, ‘Iaşirom’, ‘Golia’, ‘Bucium’, ‘Ştefan’, ‘Oana’, ‘Radu’) and resistance to diseases and frost (‘Bucium’, ‘Iaşirom’).

Sweet Cherry Cultivars

Transportation of sweet cherry fruits to distant markets and further marketing processes often takes approximately 2-3 weeks. The present study investigates the quality changes during this time period at three stages for three sweet cherry cultivars: ‘Early Burlat’, ‘Napoleon’, and ‘0900 Ziraat’. Following pre-cooling, the sweet cherries were placed in modified atmosphere packages and exposed to the following stages for the indicated durations: transportation (T) [8 days at 2 °C and 85% relative humidity (RH)]; distribution center (DC) (4 days at 6.5 °C and 80% RH), and shelf-life (SL) (2 days at 19 °C and 70% RH). Weight losses at the end of the SL stage were 3.11, 3.18, and 2.74%, respectively in ‘Early Burlat’, ‘Napoleon’ and ‘0900 Ziraat’.Fruit firmness decreased after SL as compared to that at other stages and was more remarkable in ‘0900 Ziraat’. Decreased Chroma values which indicates, the intensity or color saturation were observed in all cultivars, whereas decreased hue angle values colours expressed in degrees were observed in the ‘Early Burlat’ and ‘0900 Ziraat’. In addition, a decrease was noted in the titratable acidity of all cultivars at the end of SL. The total soluble solids, total phenolic content, and antioxidant activities were similar for all cultivars at all stages. The visual appearance scores of ‘Early Burlat’ cherries decreased at the end of SL, because of development of pitting on the fruit surface. The fruit quality changes were limited at T and DC stages; however, these changes became more distinctive during the SL period. It was thus concluded that the SL duration and conditions were of the highest significance with regard to maintenance of the sweet cherry fruit quality.

Field studies were conducted in 2011 and 2012 at the Sandhills Research Station near Jackson Springs, NC to determine the influence of weed-free strip width (WFSW) on newly planted ‘Navaho' blackberry plant growth, fruit yield, and fruit quality. Treatments consisted of 0-, 0.3-, 0.6-, 1.2-, 1.8-, and 2.4-m WFSW. Predicted blackberry yield increased from 718 to 1,015 kg ha−1at WFSW of 0 to 2.4 m. The currently recommended WFSW of 1.2 m resulted in a blackberry yield of 1,013 kg ha−1. Predicted individual blackberry fruit weight displayed a positive linear response to WFSW and increased from 3.1 to 3.6 g fruit−1at WFSW of 0 to 2.4 m. Soluble solids content (SSC) of dull black blackberry fruit was greatest (15.1 Brix) when WFSW was 0 m. Relative to a WFSW of 0 m, SSC was reduced 2.3 to 3.4% as WFSW increased from 0.3 to 2.4 m, respectively. WFSW did not influence shiny black blackberry fruit SSC, nor titratable acidity, sugar-to-acid ratio, or pH of shiny or dull black blackberry fruit or primocane number, length, and stem caliper.

The aim of this study was to characterize the capoeira-branca (Solanum granuloso-leprosum Dunal) fruits cultivated in Lavras, Minas Gerais, Brazil. The fruit growth was evaluated, from inflorescence to ripening. For this, measurements were made weekly. The fruits were harvested and separated at three developmental maturation stages (1-immature; 2-green mature; 3-mature), according to the color and size. Then, the fruits were evaluated by size, weight, color, respiration, firmness, pH, titratable acidity, soluble solids, soluble pectin, centesimal composition, vitamin C and antioxidant activity at three stages. During maturation, the fruits showed increase in mass (0.4076 to 0.9956 g), size (7.9 to 12.2 mm), glycidic fraction (15.95 to 27.23%) and ash (0.94 to 1.60%) and reduction in firmness (4.23 to 1.50 kgf), moisture (79.24 to 69.45%) and protein (3.49 to 1.41%) contents. Furthermore, there was increase in soluble solids content (8.80 to 13.80%), antioxidant activity (62.57 to 69.63 μM de trolox.g-1 and 1880.34 to 4602.40 mg.100g-1) and vitamin C (46.81 to 236.02 mg.100g-1) and a decrease in the total phenolics (257.58 to 171.00 mg.100g-1) and soluble pectin (0.92 to 0.69 mg.g-1). The fruits, even after ripening, maintained their greenish color, although less intense than that observed in immature and mature green fruits.

Over Time

The University of Florida strawberry (Fragaria ×ananassa Duch. ex Rosier) breeding program has maintained a continuous breeding effort since 1968 to develop cultivars that are highly adapted to winter production in west-central Florida. To gain insight into breeding progress over time, two advanced selections (UF1 and UF2) and 10 released cultivars, from Florida Belle (1975) to Florida Radiance (2008), were compared for various fruit quality traits in a two-location field study during the 2009–2010 season. Fruit size varied dramatically from 30.8 g for ‘Elyana’ to 16.2 g for ‘Dover’ at Balm, FL, and from 28.3 g for UF2 to 16.6 g for ‘Dover’ at Dover, FL. A linear regression of fruit size on year of release revealed an average gain of 2.6 g per year since 1975 for the cultivars and selections tested (R2 = 0.44). A similar analysis revealed a reduction over time in the proportion of cull fruit (R2 = 0.30). Gains were apparent for the redness of the internal flesh, from a colorimeter a* value of 16.1 for ‘Florida Belle’ (1975) to 34.7 for ‘Carmine’ (2002) but were not sustained for later releases and selections. Although there were significant differences among genotypes for all chemical traits affecting flavor, there were no discernable patterns over time. There were wide month-to-month variations in individual sugars and organic acids, except for citric acid, which was stable across months and locations. The ratio of soluble solids content to titratable acidity ranged widely among genotypes, from a high of 15.7 for ‘Florida Belle’ in February at Dover, FL, to a low of 6.4 for ‘Winter Dawn’ in January at Balm, FL. The observed variability and trends in fruit quality traits will help guide future genetic studies and inform decisions about future breeding priorities and selection procedures.

The Impact

Sweet cherry is a high value crop and the economic success of its cultivation depends not only on yield but also on fruit visual and nutritional quality attributes that influence consumer acceptability, as well as on fruit post-harvest performance and resistance to cracking. During the last few decades, cherry growers have tried to achieve these goals through exogenous applications of synthetic plant hormones and/or nutrients, but there is growing concern about the sustainability of the extensive use of these compounds in agriculture. For this reason, there is increasing interest in the possible adoption of different classes of biostimulants as sustainable alternatives to plant growth regulators. This research aimed to study the impact of foliar application of a novel tropical-plant extract, performed between full bloom and fruit set, on the yield and fruit quality of two important commercial sweet cherry cultivars, Kordia and Regina. The experimental design included a commercial control involving the application of a cytokinin promoter. In both cultivars, the tropical-plant extract induced significant increases in fruit yield. In addition, in the cultivar Kordia, the tropical-plant extract enhanced fruit calcium concentration, soluble solids content, flesh firmness, and skin color by 26.2%, 11.8%, 6.7%, and 12.0% (of fruits with mahogany skin color), respectively. Our results suggest that the tropical-plant extract tested as a biostimulant may be a sustainable and effective alternative to the exogenous application of synthetic hormones for sweet cherry cultivation.
