Relevance. Viral diseases can significantly reduce the yield of stone fruit crops. More than 30 viruses have been characterized on stone fruits crops, among which the most harmful are Plum pox virus (PPV), Prunus dwarf virus (PDV), Prunus necrotic ringspot virus (PNRSV), Cherry leaf roll spot virus (CLRV), Apple chlorotic leaf spot virus (ACLSV). Viral diseases monitoring is essential for controlling the viruses prevalence and choosing a control strategy. In the absence of healthy plants of a certain variety, health improvement is carried out using laboratory methods, including thermotherapy. Sanitation methods need to be improved in relation to the culture characteristics and the virus type. Of considerable interest is the development of techniques that reduce the viruses concentration when growing stone fruit trees in the field.Methods. During 2016–2020 using the ELISA (“Loewe” diagnostic kits) diagnostics of viruses on varieties and clonal rootstocks of cherry, sweet cherry and plum (660 plants) was carried out in the conditions of the Moscow region. For plant health in 2019–2021 used thermotherapy for 3 months. To study the effect of Pharmayod (“Farmbiomed”) on viruses in open ground, 24 plum plants of 5 varieties were treated with this drug at a concentration of 0.3 ml/l.Results. The total prevalence of viruses on cherries varieties was 44%, sweet cherries — 40%, plums — 59%, on clonal rootstocks — 46, 55 and 56% respectively. The highest incidence of PNRSV and PDV viruses has been established. Cherry plants of 11 varieties, free from the main harmful viruses, 4 varieties of sweet cherries, 12 varieties of plums and 9 forms of clonal rootstocks were revealed. The use of the Pharmayod on plum trees in the open field contributed to a decrease in the infection index of the studied viruses. Plum plants in a heat chamber were characterized by a higher survival rate and growth parameters in comparison with cherry and sweet cherry. After the completion of thermotherapy, a significant decrease in the index of infection in plants was noted.

The authors present data of the studying of promise stone fruit crops clonal rootstocks bread at the Krymsk FBS in the nursery and orchard. Besides, their ability of cuttings rooting, compatibility with perspective stone fruit crops cultivars were researched as well as suitability for growing in different regions of the country. The prospect of applying industrial the intensive technologies of the sweet cherry cultivation in the south of Russia, became possible in the recent years in connection with the creation of new high-quality and productive varieties and inland low-growing clonal rootstocks, more adapted to the unfavourable environmental conditions, which often occur here. The low-growing rootstocks obtained recently at the Krymsk FBS concerning their characteristics can compete with the well – known foreign semi-dwarf ones, such as Gizela 5, Gizela 6, Inmil, Piku 1, Piku 3, Piku 4. The plum and peach dwarf rootstock Upriamiets as regards vigour similar to BBA 1, reduces the growth of the trees grafted on it by 50-60 %, is characterized with early maturity and compatible with all the varieties of the tested above mentioned crops. RVL 9 is a medium-sized and Rulan 8 semi-dwarf sweet cherry rootstocks. They have a very strong root system that provides good trees anchoring in the orchard and form root sprouting when have non-considerable mechanically damage only. Sweet cherry trees on RVL 9 are by 25-30 % and on Rulan 8 35-40 % a size smaller as compared to those grafted on cherry seedlings. The fruiting begins in the third year, the yield is high. The propagation using hard-wood cuttings, which does not require special structures, has significant advantages over others methods. It ensures the high reproduction coefficient at minimum expenditures, including manpower. Therefore just this method is the most perspective for utilizing in production. Among the zoned sweet cherry clonal rootstocks easily propagate only VSL 2, VSL 1 and L 2 are propagated easily when hard-woody cuttings are applied. The study of RVL 9 and Rulan 8 as for their ability of reproduction using the above mentioned cuttings has shown that in this respect they are close to the control standard clonal rootstock VSL 2. As a result of the breeding work which we have carried out, the clonal rootstocks Upriamiets, RVL 9 and Rulan 8 have been entered in the State Register of Breeding Achievements admissed for the application in Russian Federation.

Abstract On the basis of diversity of wild types of the genus Prunus L. (P. cerasifera, P. armeniaca, P. persica, P. fruticosa, P. lannesiana, P. maackii, P. tomentosa, P. pumila, and P. incana) in the collection of the Krymsk Experiment Breeding Station, highly adaptive, medium or weak vigour clonal rootstocks for stone fruit crops with good compatibility with grafted cultivars were selected: for plum, apricot and peach - Kuban 86, VVA-1, Evrika 99, Zarevo (Glow), Alab 1, Speaker, Best, VSV-1; and for sweet cherries and sour cherries - L-2, LC-52, VSL-1, VSL-2, and RVL-9. Part of the rootstocks were tested and successfully used in different parts of Russia and some near and far countries. The applied integration of tissue culture in vitro in the selection process at the station considerably promoted the rapid introduction of new rootstocks into world production. Technologies were developed for microclonal reproduction, and green and woody cuttings. The revealed light rooting of woody cuttings of stocks Kuban 86, Evrika 99, Zarevo, Best, VSL-1, RVL-9 (50-80%) allowed to develop technology for growing of young plants on these rootstocks directly in the first field of the nursery.

The formation of costs in the cultivation of fruit crops have their own characteristics. Before establishing perennial plantings, it is necessary to grow planting material. The high cost of planting material is due to the rather sophisticated technology of growing it. Nowadays, seedlings grafted on low rootstock and have 3 or more branches are chosen to lay modern intensive gardens, thus accelerating the formation of crown in the garden and the entry of trees into the the fruiting period for 1-2 years, as well as by its growth strength and reduction of harvest costs. For cultivation of sweet cherries planting material, summer budding and winter grafting are used, but in these methods seedlings are poorly branched or well branched, but with sharp angles of lateral branches offset. Spring grafting with long stalks can become a promising and resource-saving way of obtaining branched sweet cherry seedlings. This method does not require the use of a grafting complex, provides minimal costs for grafting care, there is also no need for special methods of seedlings branchings strengthening.

This paper is about studying the rootstocks for stone fruit breeds (sweet cherry) in condition of Hissar valley in Tajikistan. Each type of rootstock has its own biological characteristics and imposes specific requirements for growing and development, both during reproduction in the mother plantation and during the growth of trees. For example, the root system in sour cherry is more superficial that of wild sweet cherry. Therefore, the care of trees grafted on sour cherry and wild cherry and of mother plantation bushes of these rootstocks cannot be same. Besides, there are very significant differences among the individual groups of rootstocks. Wild cherry, Mahaleb cherry and Lubskaya cherry are used as rootstocks in the conditions of the Hissar Valley in Tajikistan. High specificity of sweet cherry cultivar varieties depends on the rootstocks. Phenological observation were carried out in our experiments during years 2013-2018 in order to study their winter resistance, yield capacity and fruit quality. The same care for root and grafted plants was carried out during the entire observation period. At the same time a certain ratio between the leaf system of the rootstock and the graft was maintained by trimming the crown. As a result of the evolution and selection, we have identified the wild cherry forms which are distinguished by the highest yields. The most valuable cultivar varieties are Napoleon cherry and Bagration cherry. Compotes made of these varieties have received high evaluation in tasting.

The aim of this study was to evaluate the usefulness of the texture and geometric parameters of endocarp (pit) for distinguishing different cultivars of sweet cherries using image analysis. The textures from images converted to color channels and the geometric parameters of the endocarp (pits) of sweet cherry ‘Kordia’, ‘Lapins’, and ‘Büttner’s Red’ were calculated. For the set combining the selected textures from all color channels, the accuracy reached 100% when comparing ‘Kordia’ vs. ‘Lapins’ and ‘Kordia’ vs. ‘Büttner’s Red’ for all classifiers. The pits of ‘Kordia’ and ‘Lapins’, as well as ‘Kordia’ and ‘Büttner’s Red’ were also 100% correctly discriminated for discriminative models built separately for RGB, Lab and XYZ color spaces, G, L and Y color channels and for models combining selected textural and geometric features. For discrimination ‘Lapins’ and ‘Büttner’s Red’ pits, slightly lower accuracies were determined—up to 93% for models built based on textures selected from all color channels, 91% for the RGB color space, 92% for the Lab and XYZ color spaces, 84% for the G and L color channels, 83% for the Y channel, 94% for geometric features, and 96% for combined textural and geometric features.

In the present study, we utilized high throughput and Sanger sequencing to determine the complete nucleotide sequence of a putative new ilarvirus species infecting sweet cherry, tentatively named prunus virus I (PrVI). The genome of PrVI is comprised of three RNA segments of 3474 nt (RNA1), 2911 nt (RNA2), and 2231 nt (RNA3) and features conserved motifs representative of the genus Ilarvirus. BlastN analysis revealed 68.1–71.9% nt identity of PrVI with strawberry necrotic shock virus (SNSV). In subsequent phylogenetic analysis, PrVI was grouped together with SNSV and blackberry chlorotic ringspot virus (BCRV), both members of subgroup 1 of ilarviruses. In addition, mini-scale surveys in stone fruit orchards revealed the presence of PrVI in a limited number of sweet cherries and in one peach tree. Overall, our data suggest that PrVI is a novel species of the genus Ilarvirus and it consists the fifth member of the genus that is currently known to infect Prunus spp.

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.

As growers adopt and diffuse improved food crop cultivars, their investment decisions for producing new cultivars control product accessibility and directly affect the entire supply chain. In this study, we estimated growers’ willingness to invest (willingness to pay (WTP)) in cultivars with improved quality traits for five rosaceous fruit crops: apple, peach, strawberry, sweet cherry, and tart cherry. WTP values differed by crop, but fruit flavor was consistently rated one of the most important traits, with higher WTP. This information will help breeding programs focus resources to develop superior cultivars for long-term economic sustainability of the rosaceous fruit industry.

After a spring frost occurred in second half of March 2008, with temperatures below 0°C for 8 days consecutively and an absolute minimum of -5.5°C, a lot of observations have been made on the sweet cherry flowers damages. In three different orchards “Italian palmetta” trained on grassing ground soil, the percentage of the flowers killed by frost, was detected and recorded considering the different genotypes and flowers height from the ground. Furthermore, in one orchard only it was possible to find relationship between flowering stage and frost damage. The results clearly confirm our previous works about the highest mortality of the flower in the upper part ( > 1.50 m) of the canopy and in the full bloom open flowers. So, in this area, the easiness of agronomic operations, like pruning and, especially, fruit harvest, due to the crown proximity to the ground, is cancelled by the frequency of spring frost.
