Biodiversity of natural populations, biodiversity located on farm and the introduced cultivars and selections are a rich source of genetic variability in sour and sweet cherries, but they have never been bread with the aim of creating decorative varieties. Low vigour ? dwarfing and upright ? sour cherry genotypes, NS 1/16 KK and NS 1/24 KK, were selected from natural population of Fruska Gora and private arboretum, respectively. Sweet cherry selections NS 6/15 K and RS 8/27 were part of on farm conservation of genetic resources. Furthermore, reduction in vigour was achieved by defining specific combining abilities as a result of rootstock/scion interaction. The outcome of this study is unique columnar and dwarf forms that integrate specific genetic potential of varieties and selections, their interaction with rootstocks and traditional horticultural skills. Collected biodiversity is another confirmation that the Balkan peninsula is one of the most valuable secondary centres of genetic diversity and inexhaustible gene pool for breeding both, varieties and vegetative rootstocks.

SUMMARYQuinoa cultivation in Chile presents an ancient and active complex of geographic, climatic, social and cultural interactions that has determined its current biodiversity in the three main growing zones (north, central and south). Importantly, these interactions involve the participation of farmers, whose activities are at the base of seed exchange networks due to their knowledge andin situconservation of genetic diversity. The present study reports how a better understanding of farmers’ seed exchanges and local production practices could impact the genetic structure and diversity of quinoa at national scale in Chile. Using field interviews and characterization of 20 microsatellite genetic markers in a multi-origin set of 34 quinoa accessions representative of Chile and the South American region, the phenetic analysis of germplasm was consistent with the current classification of quinoa ecotypes present in Chile and Andean zone. This allowed the identification of five populations, which were represented by quinoa of Salares (northern Chile), Coastal/Lowlands (central and southern Chile), Highlands (Peru, Bolivia and Argentina) and Inter-Andean Valleys (Ecuador and Colombia). The highly informative quality of the markers used revealed a wide genetic diversity among main growing areas in Chile, which correlated well with natural geographical–edaphic–climatic and social–linguistic context to the expansion of quinoa biodiversity. Additionally, in addition to ancient seed exchanges, this process is still governed by the diverse agricultural practices of Andean farmers. Genetic erosion is considered an imminent risk due to small-scale farming, where the influence of increased migration of people to urban systems and export-driven changes to the agro-ecosystems may further reduce the diversity of quinoa plants in cultivation.

Inbreeding and coancestry coefficients were calculated for 66 sweet cherry (Prunus avium L.) selections released from four breeding programs in North America (HRIO, Vineland, Ont., IAREC, Prosser, Wash., NYSAES, Geneva, N.Y., and PARC, Summerland, B.C.). Highly used founding clones were `Black Heart', `Emperor Francis', `Empress Eugenie', `Napoleon' and `Windsor'. Coefficients of coancestry between all selections and these clones averaged 0.038, 0.045, 0.060, 0.091, and 0.033, respectively. In these five founding clones, coefficients of coancestry in self-compatible selections were over twice as much as those in self-incompatible selections except `Windsor'. In the analysis of coefficients of coancestry between self-incompatible and self-compatible sweet cherry, almost 20% of self-incompatible selections represent more than a half-sib relationship (0.125) to self-compatibles. Increasing and maintaining genetic diversity is needed in sweet cherry breeding program in North America for continued breeding progress.

AbstractPlums, sweet cherry, and sour cherry trees were spaced 4.5 m × 1.5 m to be trained to “Y” and “V”-trellising systems for mechanical harvesting, with a canopy contact harvester, attending to obtain fruits meeting the requirements of the fresh fruit market. The applied trellising systems were compared with the standard central leader system at the same spacing. The most of trellised trees grew less vigorously than the standard trees, and after 3 years of training, the trees were suitable for mechanical harvesting with the harvester designed at the Research Institute of Horticulture in Skierniewice. The trellised trees were able to set as many fruitlets as those grown in the form of central leader and gave a comparable yield, but differences between cultivars were significant. Light interception in the third year after planting was lower for trees of sour cherry and plum growing in the “Y”-20° and “V” in comparison to the trees with central leader. Illumination of trellised canopies at the level of 0.7 and 1.5 m was the most favorable in “V” system when compared to control and “Y” training systems. Cost of construction for the trellising systems of stone fruits calculated per 1 ha was two times higher when compared with the standard system.

The scientific article presents the results of research work on the study of varietal characteristics of sour cherry and sweet cherry and methods for artificial formation of tree crowns at the level of photosynthetic activity of leaves with the orientation of growing trees by their intensive technology. Zoned cherry varieties Shubinka, Podbelskaya and Shpanka chernaya, sweet cherry Bakhor, Revershon and Drogana jyoltaya grown on a weak vegetatively propagated rootstock BBA-1 and BCL-2 (Krymskiy-5) were used as the object of the study. As a result of the conducted research, it was found that the optimal crown system for varieties of sour cherry and sweet cherry is a five skeletal wall. The formation of the crown in these forms contributes to a decrease in the volume of the crown by an average of 25%, at which the net productivity of leaf photosynthesis in comparison with the usual formation of the crown — freely growing and sparse-tiered shape, reaches 34.73 g/m2 per day. With the formation of bushy crown forms in cherries and sweet cherries, the level of leaf formation improves and the chlorophyll content in the leaves increases to 13.42 mg /g of fresh weight of leaves.

Corylus heterophylla and Corylus kweichowensis are economically and ecologically important nut-producing woody shrubs that are distributed across northern and southern regions of China. However, few studies have examined the genetic diversity and genetic relationships between C. heterophylla and C. kweichowensis, and their taxonomic relationships have been questioned. In this study, 796 individuals collected from 34 natural populations (21 C. heterophylla and 13 C. kweichowensis populations) were investigated to assess the genetic diversity and population structure using 11 microsatellite loci. Analysis of molecular variance revealed that genetic differentiation of C. heterophylla and C. kweichowensis within populations accounted for 93.57% and 88.91% of total variation, respectively. The C. heterophylla and C. kweichowensis populations as a whole group were analyzed by multiple programs, which showed that the 34 populations were divided into two genetic clusters. One cluster included 21 C. heterophylla populations, and the second cluster contained 13 C. kweichowensis populations. We conclude from these results that C. heterophylla and C. kweichowensis are distinct species. The Mantel test showed that the genetic distance was significantly correlated with the geographic distance (r = 0.580, P < 0.001). The populations of C. heterophylla [e.g., populations WC (Weichang), MS (Mishan), and WA (Wu’an)] and C. kweichowensis [e.g., populations YX (Yuexi), ZP (Zhenping), LA (Lin’an), and TB (Taibai)] with high allelic richness are considered suitable for in situ conservation. Our study provides valuable information for breeding and conservation of genetic resources of C. heterophylla, C. kweichowensis, and related species.

Cherries are known as health friendly fruits due to their abundant phytochemical compositions. This study was conducted to determine phytochemical and pomological fruit properties of different cherry species including mahaleb (Prunus mahaleb L.), wild sweet cherry (Prunus avium L.), wild sour cherry (Prunus cerasus L.), two sweet cherries (‘Napoleon’ and ‘Starks Gold’) and one sour cherry (‘Kütahya’) cultivars. For this aim, together with various pomological traits, total phenolics and anthocyanin contents, antioxidant capacity, organic acids, sugars, were analyzed in fruits of relevant genotypes. Results of all examined traits significantly varied between genotypes. Mahaleb showed the highest TSS (30.17%), fructose (8.71 μg/g) and glucose (20.74 μg/g) contents. Wild sour cherry gave the highest antioxidant capacity (13.25 mmol TE/kg total weight), anthocyanin (351.0 mg Pg-3-glk/kg total weight), citric acid (0.56 μg/g) and malic acid (2.96 μg/g) contents. As a rootstock, mahaleb was found to be superior in some of the traits when compared to wild sweet cherry. Significant correlations were observed between various traits. Additionally, principal component analysis (PCA) revealed different relationships among the traits and evaluated genotypes.
