The sweet cherry genetic collection of RUE "Institute of Fruit Growing" is including 273 accessions, which have been studied for the main economic and biological traits. The main features for selection are large-fruited combined with winter hardiness and resistance to cherry leaf spot. After an evaluation of the collection, three large-fruited accessions with tough pulp of the fruit were selected. The Ukrainian early fruit ripening variety ‘Annushka’ was selected among the introduced cherry varieties. This variety has large fruits of excellent taste and is characterized by high winter hardiness. Two Belarusian promising selections ‘84-10/98’ (‘Narodnaya’ o.p.) and ‘94-30/41’ (‘Vityaz’ × ‘Aelita’) were selected on these grounds. Selection ‘84-10/98’ has a medium and ‘94-30/41’ has late fruit ripening terms.

The results of the evaluation of the genetic cherry collection of the Republican Unitary Enterprise “Institute for Fruit Growing” for winter hardiness, resistance to coccomycosis and large-fruited are presented. Among the studied 213 cherry accessions 6 highly winter resistant, 105 resistant to cherry leaf spot, three genotypes with very large fruits (varieties Krupnoplodnaya, Lyubava Donetskaya, Legenda Mliyeva, the fruit weight of which exceeds 8.3 g) and 11 accessions with a fruit weight exceeding 7.0 g (varieties Krasavitsa, Dar Mlieva, Donetskaya Krasavitsa, Donchanka, Sashenka, Ugolek, Yaroslavna, Lambert Compact, hybrids 10/98, D-7-87, № 5) were identifi ed. Two sources (varieties of sweet cherries of the Belarusian breeding Severnaya and Syubarovskaya), combining high winter hardiness and resistance to coccomycosis, were revealed. On the base of the identified genotypes a characteristic collection of sources of winter hardiness, large-fruited and resistance to coccomycosis has been formed for use in the new sweet cherry breeding program.

Sweet Cherry Cultivars

The aim of this study was to evaluate the cherry leaf spot (CLS) incidence on 12 sweet cherry cultivars in integrated sweet cherry production in three consecutive years from 2010 till 2012. Assessed cultivars (cvs.) were ’Aida’, ’Axel’, ’Biggareau burlat’, ’Blaze Star’, ’Celeste’, ’Germersdorfi 3’, ’Izabella’, ’Katalin’, ’Krupnoplodnaja’, ’Linda’, ’Sunburst’, ’Vera’Results showed that year had an essential effect on the CLS disease incidence. Cultivars showed great differences within years. Cultivar ’Celeste’ showed the lowest disease incidence on leaves in all years lower than 10%. The largest disease incidence on leaves was on cv. ’Sunburst’ in 2010, on cv. ’Germersdorfi 3’in 2011 and on cv. ’Axel’ in 2012. Disease incidence on these cultivars ranged between 10 and 25%.

Sweet Cherry Cultivars

The aim of this study was to demonstrate the 10% threshold level for cherry leaf spot incidence on 23 commercial sweet cherry cultivars in two training systems. Twenty three cherry cultivars were evaluated in the two training systems with a spacing of 4 x 1 m and with a spacing of 2 x 5 m. Results showed that leaves of many cultivars were heavily infected, e.g. cultivars (cvs) ’Biggareau Burlat’, ’Sunburst’, while others showed low disease incidence e.g. cvs ’Celeste’ and ’Blaze Star’. According to the 10 % threshold level, cv ’Celeste’ proved to be the most resistant cultivar to leaf infection, while cv ’Münchebergi korai’ exceeded extremely the 10% threshold level. Leaf spot incidence was affected by training system on most cultivars. Thirteen cultivars had less than 10% infection in the 4 x 1 m spacing (i.e. they did not reach the 10% disease threshold level). At the same time, only 3 cultivars showed less than 10% infection in the 5 x 2 m spacing.

Investigations were made on 12 sweet cherry cultivars (‘13-S-22-8’, 'Sunburst', `Kozerska'., 'NY 13791', 'Royalton', 'NY 13688', 'Hartland', `Sumerset', 'Pollax', 'Patriotka Krima', 'Castor', and `Lapins') in an experimental orchard of cherry cultivar collection in the Institute of Agriculture at Kyustendil, Bulgaria during the period of 1997-2003. The trees were planted in 1996. All cultivars were grafted on Prunus mahaleb. Four biological properties of the cultivars were assessed such as blooming time, resistance to late spring frost, fruit ripening and fruit mass. Among cultivars, a good resistance to late spring frost was observed on cultivar 'Sunburst'. The fruit mass varied between 4.2 g (cv. 'Patriotka Krima') and 8.5 g (cv. `Sunburst'). The susceptibility of the cherry cultivars to cherry leaf spot caused by Blumeriella jaapii was assessed in mid-September in each year. The estimation of the rate of attack was made according to the grade of Townsend and Neuberger. All cultivars showed symptoms of cherry leaf spot but the degree of susceptibility was different. Cultivar `Patriotka Krima' was the least susceptible, while cultivar `Somerset' was the most susceptible to Blumeriella jaapii.

Abstract This chapter provides information on the processes that occur in the sweet cherry fruit during ripening prior to harvest. Some pre-harvest disorders, such as fruit cracking, and their management are presented. Some factors to consider during the harvesting of the fruits are also discussed, along with various harvesting techniques. Some postharvest fruit quality considerations are highlighted and the importance of postharvest temperature and humidity control and safe transport of fruits from the orchard to the packing house are pointed out.

The investigations were made in the experimental sour cherry orchard from the Institute of Agriculture, Kyustendil, Bulgaria, during the period 2010-2014, in order to compare conventional and integrated sour cherry protection against cherry leaf spot and cherry fruit fly. Two variants were investigated, with two different treatment approaches for the control of cherry leaf spot and cherry fruit fly. Variant 1 – cherry leaf spot was controlled by protective treatments with dodin and tebuconazole + trifloxystrobin and cherry fruit fly was controlled by treatments with deltametrin and thiacloprid, independently of density. Variant 2 - cherry leaf spot was controlled by post-infection (curative) treatments with tebuconazole + trifloxystrobin and cherry fruit fly was controlled by treatments based on biological threshold: 10-11 cherry fruit fly females caught in traps up to the moment for chemical treatment. It was established that Blumeriella japii can be successfully controlled by post-infection treatments and by this the number of insecticide treatments was reduced. The treatments against cherry fruit fly can be avoided or reduced when the attack control is based on the biological threshold established in the studied area.

High Quality Genome

Blumeriella jaapii is the causal agent of cherry leaf spot (CLS), the most important disease of tart cherry in the Midwestern United States. Infection of leaves by B. jaapii leads to premature defoliation, which places trees at heightened risk of winter injury and death. Current management of CLS relies primarily on the application of three important fungicide classes, quinone outside inhibitors, sterol demethylation inhibitors, and succinate dehydrogenase inhibitors. Here, we present the first high-quality genome of B. jaapii through a hybrid assembly of PacBio long reads and Illumina short reads. The assembled draft genome of B. jaapii is 47.4 Mb and consists of 95 contigs with a N50 value of 1.5 Mb. The genomic information of B. jaapii, representing the most complete sequenced genome of the family Dermateaceae (Ascomycota) to date, provides a valuable resource for identifying fungicide resistance mechanisms of this pathogen and expands our knowledge of the phytopathogenic fungi in this family.
