The soil and climate conditions in Romanian Northeastern area are favorable for cherry cultivation, but some times can occurred some calamities. The paper presents a study which during 2020 at the Research Station for Fruit Growing (N-E of Romania), using five sweet cherry genotypes as research material: ‘Van’, ‘Croma’, ‘Elaiași’, ‘HC920402’, ‘HC930208’. Observations and determinations were performed in regards to the frostdamages, the main growing and phenological stages and the physical and chemical traits of the fruit. The phenological stages were evaluated for beginning of flowering and fruit ripening (expressed in growing degree-days, GDD). For these sweet cherry cultivars, the highest values concerning the fruit’s weight have been recorded for ‘Elaiași’ (9.15 g) and ‘HC920402’ (7.7 g), while fruit’s equatorial diameter have ranged between 23.21 mm and 25.16 mm. The content of soluble dry solids (SDS) was between 14.6 and 20.2 °Brix. The proposed objective aims at introducing in the assortment the new varieties with quality fruits and their resistance to cracking, with ripening time at the extremities of the sweet cherry season.

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.

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.

A study was carried out during 2005 in the Maule Region of Chile (34.56°S, 71.5°W) to evaluate the effect of the co-application of Promalin® at different bud phenological stages and notching at different distances on lateral branching of three sweet cherry cultivars. Treatments significantly increased total feather length in comparison to the untreated control only in the case of ‘Bing’. Total feather growth in these cases was more than double that of control trees. On ‘Lapins’ treated trees, total number of lateral shoots was in most cases significantly increased. In ‘Stella’ trees, total feather length and total number of lateral shoots were not affected by treatments.

AbstractRain-induced fruit cracking is a major problem in sweet cherry cultivation. Basic research has been conducted to disentangle the physiological and mechanistic bases of this complex phenomenon, whereas genetic studies have lagged behind. The objective of this work was to disentangle the genetic determinism of rain-induced fruit cracking. We hypothesized that a large genetic variation would be revealed, by visual field observations conducted on mapping populations derived from well-contrasted cultivars for cracking tolerance. Three populations were evaluated over 7–8 years by estimating the proportion of cracked fruits for each genotype at maturity, at three different areas of the sweet cherry fruit: pistillar end, stem end, and fruit side. An original approach was adopted to integrate, within simple linear models, covariates potentially related to cracking, such as rainfall accumulation before harvest, fruit weight, and firmness. We found the first stable quantitative trait loci (QTLs) for cherry fruit cracking, explaining percentages of phenotypic variance above 20%, for each of these three types of cracking tolerance, in different linkage groups, confirming the high complexity of this trait. For these and other QTLs, further analyses suggested the existence of at least two-linked QTLs in each linkage group, some of which showed confidence intervals close to 5 cM. These promising results open the possibility of developing marker-assisted selection strategies to select cracking-tolerant sweet cherry cultivars. Further studies are needed to confirm the stability of the reported QTLs over different genetic backgrounds and environments and to narrow down the QTL confidence intervals, allowing the exploration of underlying candidate genes.

Aim. Ukrainian breeders have created a large number of sweet cherry cultivars, which still remain almost unexplored at the molecular level. The aim of our study was to identify the self-incompatibility alleles (S-alleles) in Ukrainian sweet cherry cultivars and landraces, and to elucidate, to which cross-incompatibility group the cultivars belong. Methods. The PCR was conducted using consensus primers to the first and second introns of S-RNAse gene and to the single intron of SFB gene. The electrophoretic analysis of the PCR products of the second intron of S-RNAse was carried out in agarose gel, whereas detection of fluorescently labeled DNA fragments of the first S-RNAse intron and the SFB intron was performed using a genetic analyzer. Results. The S-alleles of 25 Ukrainian sweet cherry cultivars and 10 landraces were identified. The S-alleles frequencies and affiliation of cultivars and landraces to the groups of cross-incompatibility were determined. The obtained data can be used in breeding programs and by planning of industrial plantings. Conclusions. In the study, 12 different S-alleles and 79 S-haplotypes were identified. The S1, S3, S4, S5, S6 and S9 alleles are the most widespread among Ukrainian sweet cherry cultivars and landraces. The high frequencies of S5 and especially of S9 alleles are characteristic for the Ukrainian cultivars and distinguish them from other European ones. For the Ukrainian sweet cherry cultivars, the XXXVII (S5S9) cross-incompatibility group appeared to be the most numerous.Keywords: Ukrainian sweet cherry cultivars, S-locus, Sgenotypes, self- and cross-incompatibility, Prunus avium.

The tensile strengths of graftings between three selected sweet cherry cultivars and five selected cherry rootstocks were determined with an Instron instrument 6, 12, and 18 weeks after grafting and compared with the tensile strength of self-grafted rootstocks and graftings of rootstocks used as scions. The combination of sweet cherry cultivars and rootstocks was selected to provide a range of compatibility based on preliminary work. The tensile strengths of sweet cherry cultivars grafted on different rootstocks never exceeded the tensile strengths of the self-grafted rootstocks. Rootstocks grafted as scions on Prunus avium L. rootstocks and self-grafted rootstocks produced some of the strongest unions tested and also produced union strength much faster than any of the other combinations. The degree of compatibility was quantified and results indicated that if this value was below 0.2, measured 18 weeks after grafting, it corresponded to combinations with major risks of delayed incompatibility.Key words: tensile strength, grafting, compatibility, sweet cherry, Prunus avium.

The aim of this study was to evaluate and compare the content of a number of bioactive compounds and antioxidant activity of fruits of selected local and commercial sweet cherry (Prunus avium L.) cultivars. The experiment showed that the selected cultivars of sweet cherries differ significantly in the content of polyphenolic compounds and carotenoids. The fruits of commercial sweet cherry cultivars were, on average, richer in polyphenols (the sum of phenolic compounds determined chromatographically), flavonoids, as well as anthocyanins and were characterized by higher antioxidant activity when compared to the local, traditional cultivars. In the group of the traditional sweet cherry cultivars, particular attention could be paid to Black Late cv., showing the highest antioxidant activity of fruits. In the group of commercial sweet cherry cultivars, Cordia and Sylvia fruits could be recognized as being rich in bioactive compounds with high antioxidant activity. Yellow skin cultivars were characterized by the highest concentrations of carotenoids. Strong positive correlations between the identified bioactive compounds and antioxidant activity of fruits were also found. Although different cultivars of sweet cherries show a high variability in phenolics and carotenoids profiles as well as in the antioxidant activity of fruits, they all should be, similarly to other types of cherries, recognized as a rich source of bioactive compounds with an antioxidant potential.

Sweet cherry (Prunus avium L.), originated around the Caspian and Black Sea, is an important fruit tree species of economic interest, and hence, breeding and conservation are requested (. Genetic analysis at the molecular level can be used effectively to study molecular polymorphism existing between intraspecific and interspecific tree species and phylogenetic relationships between them and their hybrids. The purpose of this study was to characterize and determine genetic relationships among the sweet cherry native genotypes belonging to Fruit Research & Development Station Bistrita, Romania, using RAPD markers. To eliminate the existence of possible synonyms from national romanian collection, we collect four Van cultivars, from four different national collection. For molecular analysis of the 16 varieties of sweet cherry were considered 13 RAPD primers selected from the literature. They were later used to determine the genetic variability at the molecular level using PAST program, and the dendrogram was generated based on Jaccard’s genetic distance. The dendrogram constructed by PAST software. The quantity and quality of the DNA obtained was suitable to achieve PCR amplification step. Only seven out of the 13 RAPD primers have generate polymorphic bands. The rest of seven were monomorphics. The most polymorphic primer was OPB10 which generated 11 bands from which 100% were polymorphic.Seven RAPD primers generated a high level of polymorphism which allowed to divide these cherry varieties into two groups according to their genetic geographical origin and the pedigree.
