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.

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.

Fruit were studied to determine if anatomical and physiological features explain the difference in susceptibility to rain-induced cracking of the sweet cherry (Prunus avium L.) cultivars Sue (resistant), Lapins (moderately resistant), and Van (susceptible). Water uptake as a percentage of fruit weight at cracking tended to be high in `Sue', medium in `Lapins', and low in `Van' and was related to the percentage of cherries remaining sound after 4 hours of immersion, suggesting that this trait is a factor in determining resistance. Mesocarp cells of `Sue' were more rectangular in section than those of the other cultivars. Skin elasticity and thickness of the cuticle did not explain resistance of `Sue' to cracking. Magnesium, copper, and phosphorus mineral contents were not related to cracking susceptibility, but the content of calcium, which influences cell wall integrity, in the epidermis of `Sue' was lower than in `Van'. Calcium content was not different in the hypodermal cells of the two cultivars. None of the anatomical features examined in this study explain the resistance to fruit cracking of `Sue'.

Sweet Cherry Cultivars

During 2000 and 2007, rootstocks of different vigor have been tested in a high density sweet cherry orchard with 'Vera '® and 'Axel'® cultivars at 4 x 2 meter row and plant distance. Trees are trained to Hungarian Spindle with permanent basal branches; in the alley way naturally grown grass is managed by mowing. The first considerable fruiting was in 2004. Every year we measured trunk and canopy parameters of the trees, productivity and fruit size. Our conclusion is that the rootstocks considerably affected the growth, precocity, as well as tree and orchard productivity, fruit weight of sweet cherry cultivars, but these rootstock effects are modified by cultivars, except for growth vigor. According to our results Cema, SL 64, and Bogdany are vigorous rootstocks, moderate vigorous are MaxMa 97, Pi-Ku I , and Tabel® Edabriz, Gisela® 5 and Prob are dwarfing rootstocks. Besides the precocious Gisela® 5 also mahaleb rootstocks CEMA, Bogdany and SL 64 showed considerable precocity, which can be explained by the larger bearing surface to the time of turning to bearing, and a similar or relative large density of burse shoots on fruiting branches. Cumulative yield of 'Axel'® was the highest on Bogdany and on Cerna, contrary to Gisela® 5, which produced only 50% of the previous ones. Cumulative yield of 'Vera'® was the highest on SL 64, and no significant difference was found, compared to trees on rootstocks Cema, Bogdany and Pi-Ku I . Cumulative yield production of trees was smaller on Gisela® 5, Prob, Max Ma 97 and Tabel® Edabriz rootstocks. Corresponding to the literature data of yield efficiency calculated on TCSA basis was highest on Gisela® 5 rootstock. but the efficiency calculated on canopy volume of 'Axel•® trees was similarly high on CEMA and Bogdany, and that of 'Vera'® trees relatively high on CEMA, Bogdany, SL 64 and PiKu I rootstocks. When calculating orchard efficiency al spacing 4 x 2 meters (1250 tree/ha), we received highest yield values on Bogdany, CEMA, SL 64, and PiKu I rootstocks, with large fruit weight. Rootstocks also affect fruit weight. We measured the largest fruit weight on trees on Bogdany.

AbstractTo study possibility of protection of sweet cherry fruit against cracking several rows of ‘Lapins’ sweet cherry (Prunus avium L.) trees grafted on ‘Colt’ rootstock, spaced 5 × 2.5 m and trained to a central leader were covered with a plastic foil to a height of 5 m. Several rows were left uncovered as a control. In the years 2016 and 2018, sun irradiation, air temperature and fruit quality were evaluated. The plastic cover reduced solar irradiation under the tunnel roof by around 40%. Light distribution within tree canopies was depleted by roughly 50%, but in the lower parts of the tree canopies, it was reduced to 6%, which is below the critical level (20%) estimated for apple trees. These results indicate the necessity to remove the covers as soon as possible after harvesting. Mean daily temperature near the ground was lower under the covers than outside, but at the height of 4.0 m, daily mean temperature was 0.4 °C higher and mean temperature during midday hours was 1.5 °C higher. The plastic covering reduced the fruit cracking from about 20% to 2% in both seasons but did not affect the fruit yield. The plastic covering did not affect the firmness and antioxidant activity and total anthocyanin content, but in the year 2018, it reduced the mean fruit weight, soluble solid, titratable acidity, dry matter and total polyphenols content.

Abstract The work is focused on the evaluation of variability of morphological and pomological characteristics of several old sweet cherries (Prunus avium L.) that were found in different Slovak regions. The experimental work has been performed during two years, 2014 and 2015. The following characteristics according to the descriptor list of subgenus Cerasus were evaluated - period of flowering and ripening, morphological characteristics of the flowers, fruit size, fruit weight, and quality parameters. The results showed high variability of evaluated accessions. From the 13 surveyed localities, the most valuable accessions were found in the locality Hornį Streda - places Čachtice, Krakovany, Nitra, and Brdárka. During the collecting expeditions, 170 accessions of sweet cherry, with fruit of the different quality were found. The most interesting accessions were grafted onto rootstocks with different intensity of growth (Prunus avium L., Prunus mahaleb L., and ‘Gisela5’). Some of the selected cherry accessions can be used for commercial growing after tests, while some of them can be used only for collection of genetic resources and as potential genitors in breeding programmes.

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.

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.

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.
