Sweet Cherry Cultivars

Pomological properties of 11 newly sweet cherry cultivars grafted on Colt rootstock were studied in the region of Macva over a three-year period (2010- 2012). An investigation has included phenological traits (flowering and maturing), the elements of productivity (number of flowers in an inflorescence, fruit set and yield), the most important fruit characteristics (physical, chemical and sensory), and fruit cracking index. Average time of flowering of tested cultivars was in the first and the second decade of April, while the maturing time was between 15 May (?Early Lory?) and 20 June (?Penny?). The highest yield was achieved by cultivars ?Giorgia?, ?Sunburst?, and ?Crystalina?. Large fruit size was found in cultivars ?Penny?, ?Santina?, ?Sunburst?, ?Olympus?, and ?Kordia?. The lowest susceptibility to fruit cracking was manifested in cultivars ?Early Lory? and ?Giorgia?. Cultivars ?Kordia? and ?Cristalina? were given the highest sensory ratings. Overall, the best results were shown by medium-early season cultivar ?Santina?, which can be recommended for commercial cultivation. In addition, the early-season cultivar ?Early Lory?, and the late-season cultivar ?Kordia? can also be recommended for cultivation.

Lapins and Sunburst are new self-compatible, dark fleshed sweet cherry cultivars named by Agriculture Canada Research Station, Summerland, British Columbia. Lapins matures late in the cherry season and has outstanding split resistance combined with other desirable fruit and tree characteristics. Testing to date has shown it to be better than presently grown cultivars. Sunburst is an early cultivar ripening in Bing season and is outstanding because of very large fruit size and very heavy yields. It should be a suitable cultivar in locations where fruit set is a problem and lengthy storage is not required.Key words: Prunus avium, self-compatible, split resistance, cultivar description

Sweet Cherry Cultivars

Fruit cracking is one of the main concerns in sweet cherry production and is caused by a heavy rainfall before and during the harvest. This physiological disorder leads to severe economic losses, which can be more or less effective depending on the cracked region of the fruit: in the cheeks (side cracks), in the stylar scar region, or in the stem cavity region. Sweet cherry cracking can be affected by several factors such as cultivar, growing conditions, rootstock, fruit size, flesh osmotic potential, cuticular characteristics of the skin, and stage of fruit development. In this sense, the objective of this work was to evaluate the cracking incidence in two sweet cherry cultivars (Early Bigi and Lapins grafted on “Saint Lucie 64” rootstock) and correlate the cracking index with other quality parameters. Fruits were harvested on 2 May (cv. Early Bigi) and on 27 May (cv. Lapins) 2019 at their commercial ripening stage. In the field, the total yield and the trunk cross-sectional area were determined for each tree in order to calculate the yield efficiency. In the laboratory, the cracking index was determined in 150 fruits without visual defects. In addition, fruit size and weight, wax content, flesh firmness, epidermis rupture force, total soluble solids, pH, titratable acidity, and maturity index of 30 fruits were also evaluated. In general, all the analyzed quality parameters were influenced by the cultivar, being that cv. Lapins presented larger, heavier, firmer, and sweeter fruits, with more acidity and higher maturation index. However, cv. Lapins also presented higher cracking index, which was positively correlated with all the parameters above-mentioned and negatively correlated with the wax content. In fact, cv. Early Bigi presented a high wax content and simultaneously a low cracking index. The stylar scar region cracks were the most prevalent in both cultivars. These results allowed us to conclude that, in the North Portugal region, the Lapins cherries presented better quality attributes than the Early Bigi cherries. However, the latter are still very valuable to the region due to its early ripening. Additionally, it was also possible to conclude that bigger, firmer, more mature, and with lower wax content cherries were more sensitive to cracking than the smaller fruits, soft-fleshed, less mature, and with higher wax content.

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.

AbstractThe aim of the work was to select pollinators for sweet cherry cultivars: ‘Vanda’, ‘Techlovan’, ‘Syl–via’ and ‘Regina’, which are of great economic significance in Poland. As pollinators, three or four different cultivars with the same or similar flowering time as the pollinated cultivars were evaluated annually. The pollinators belonged to different incompatibility groups. Pollination was carried out over four consecutive seasons. Assuming that for a good yield more than 20% of the flowers should develop fruits, a good polli–nator for the cv. ‘Vanda’ was ‘Techlovan’, and for the cv. ‘Regina’ - ‘Sylvia’. The cv. ‘Techlovan’ was pollinated to best effect by ‘Vega’, and the cv. ‘Sylvia’ by ‘Regina’, but the setting of fruits in the last two combinations was moderately good. Low to moderately good fruit setting but depending on the year was observed in the combinations ‘Sylvia’ x ‘Summit’, ‘Regina’ x ‘Summit’, and ‘Regina’ x ‘Rainier’. Cultivar ‘Summit’ for ‘Sylvia’, and ‘Summit’ and ‘Rainier’ for the cv. ‘Regina’ should not be used as pollinators because the low percentage of fruit set obtained annually does not guarantee a satisfactory yield.

Plant Sci. 94: 1555–1558. ‘SPC136’ (Suite Note™) is a new early-season sweet cherry being released for commercial production by the Agriculture and Agri-Food Canada sweet cherry breeding program at Summerland, BC, Canada. Harvest timing in Summerland (Jul. 09) is similar to that of ‘Bing’ or ‘Van’ but fruit size is much larger (over 12 g). Fruit firmness, soluble solids content and susceptibility to rain splitting resemble those of other cultivars of similar harvest timing, but stem detachment force is higher. The trees are not self-fertile and bloom late in the cherry blossom season.

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.

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%.
