AbstractThe study was performed at the Experimental Station of Agriculture - Khan Krum in the period 2018-2019. The experimental plantation was established in 2001, the early Bigareau Burlat, middle early Bing and the late Germersdorfer and Van were tested. The planting material was produced on a mahaleb rootstock. The distance of planting was 6 meters interrow spacing and 5 meters intrarow spacing. The experiment was based on three replications each of them reported on a separate tree. When analyzing the frost percentage of flowers, 400 blossoms were taken from three levels of the crown of each tree, the same number of fruits were taken to determine the cracking percentage. Percentage of damaged blossoms, yield kg/ha and percentage of fruit cracking as a result of fallen rains during harvest were established. The purpose of the study is to investigate the influence of abiotic factors on the yield and quality of four sweet cherry cultivars. In this regard, the frost percentage in the range of values was 67,3 - 100%. Bigareau Burlat yield was not obtained, and it was relatively low from Germersdorf and Bing (20,1 - 24,6 kg/ha) at Van 84,6 kg/ha. The number of cracked fruits due to fallen rains during harvest was relatively high in Van and Bing (39,8 - 47,4%), while in the Germersdorf cultivar it was lower - 21,2%.

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.

Susceptibility of 5 sweet cherry cultivars, grafted on Gisela 5, to rain induced fruit cracking was studied in the region of Sarajevo, during a two – year period (2010 – 2011). Testing of fruit cracking was done using index by Christensen. During the testing period, significant differences in susceptibility to fruit cracking among both the cultivars and the years of testing were found. All the cultivars had the highest fruit cracking index in 2010 year. The highest susceptibility to rain induced fruit cracking was evidenced in cultivar ‘Burlat’ during both years. Cultivars ‘Kordia’, ‘Regina’, ‘Karina’ and ‘Schneider's Spӓte Knorpelkirsche’ were moderately susceptible to fruit cracking.

Sweet Cherry Cultivars

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.

Abstract Background: Rain-induced fruit cracking is a major physiological problem in most sweet cherry cultivars. For an in vivocracking assay, the ‘Christensen method’ (cracking evaluation following fruit immersion in water) is commonly used; however, this test does not adequately simulate environmental conditions.Herein, we have designed and evaluated a cracking protocol, named ‘Waterfall method’, in which fruits are continuously wetted under controlled conditions. Results: The application of this method alone, or in combination with ‘Christensen method, was shown to be a reliable approach to characterize sweet cherry cracking behavior. Seventeen cherry cultivars were tested for their cracking behavior using both protocols, and primary as well as secondary metabolites identification was performed in skin tissue using a combined GC-MS and UPLC-MS/MS platform. Significant variations of some of the detected metabolites were discovered and important cracking index–metabolite correlations were identified. Conclusions: We have established an alternative/complementary method of cherry cracking characterization alongside to Christiansen assay.

The promotion of a cherry assortment with constant yield, low vigour of the trees, self-fertility and high productivity, resistance to biotic and abiotic factors and with ripening at the extremities of the cherries maturation season, represents a permanent concern of researchers. In this context, considering the current patrimonial situation and the perspectives of growing sweet cherry trees in the Iasi area, under a privatized agriculture, the selection of new cultivars to be introduced in the assortment requires a special attention. Analyzing the values of the fertility index during the three years of study (2018 – 2020) it was observed that all the cherry cultivars excepting ‘Kordia’ are highly fertility with values between 30.0% and 66.2%. The cultivars ‘Bucium’, ‘Croma’, ‘Van’, ‘Maria’, ‘Stella’, ‘Cătălina’, ‘Margonia’ and ‘George’ have large fruits (over 7 g and over 22.5 mm) and ‘Kordia’ (6.3 g and 21.1 mm), ‘Scorospelka’ (6.2 g and 22.3 mm), ‘Cetăţuia’ (6.0 g and 22.0 mm) and ‘Rivan’ (5.9 g and 21.6 mm) have small fruits. For ‘Scorospelka’, ‘Cetăţuia’ and ‘Rivan’, the fruits are large in comparison with other early cultivars. The values of soluble dry substance (SDS) varied between 13.6% (‘Scorospelka’ and ‘Rivan’) and 18.9% (‘Maria’). However, statistically, cultivars ‘Maria’ (18.9%), ‘Bucium’ (18.3%) and ‘George’ (18.1%) recorded superior values in comparison with all the other cultivars.
