Determination of S‐Allele Combination in an Italian Apple (Malus × domestica Borkh.) Germplasm Core Collection

ABSTRACTAn S‐RNase‐based gametophytic self‐incompatibility (GSI) system, a mechanism that forces outbreeding by preventing self‐fertilization, characterizes the genus Malus. Knowledge of the self‐incompatibility (S) genotypes of apple cultivars is crucial for choosing pollen donors for fruit production and breeding. Even though the S‐allele of most commercial apple cultivars has already been identified, limited information is available about the S‐allele diversity within local germplasm collections. In this study, 67 S‐allele combinations of local apple accessions were identified. The allele S3 was the most common among local apple accessions followed by S1 and S7. The main aim of this study is to provide new information on cultivar compatibility, and these results will be used to set up new parent selection in apple breeding programmes as well as pollinator selection for the commercial orchard.

Comparative Analyses of Biologically Active Substances and Antioxidant Activity in Fresh and Stored Fruits of Apple Varieties from the Republic of Tajikistan

Our purpose was to carry out a comparative phytochemical analysis of fruits (both fresh and stored for 1 month) of two local apple varieties of the Republic of Tajikistan. Assays were carried out to quantify total phenolic compounds, flavonols, catechins, tannins, phenolcarboxylic acids, pectins, and protopectins by UV spectrometry and ascorbic acid by titration. The profile and levels of phenolic compounds were investigated by high-performance liquid chromatography. Antiradical activity was quantitated by means of free radical DPPH (2,2-diphenyl-1-picrylhydrazyl). In fresh fruits, total levels of tannins (19 mg/g) and phenolcarboxylic acids (15 mg/g) (including chlorogenic acid: 451 μg/g) and of a flavonol (quercetin: 26 μg/g) and two catechins [epigallocatechin (173 μg/g) and L-epicatechin (50 µg/g)] were shown to be higher in the Surkhseb apple variety than in the Kosimsarkori variety. The antioxidant activity of water–ethanol extracts from Surkhseb apples (20 mg/mL) was also higher in comparison with Kosimsarkori apples. In the latter, concentrations of other detected biologically active substances, such as flavonols (0.78 mg/g), ascorbic acid (65 mg/100 g), and pectins (37 mg/g), were found to be higher, suggesting that the fruits of this apple variety have biological effects other than antioxidant, potentially anti-inflammatory, or antidiabetic. Further phytochemical and pharmacological studies on Kosimsarkori fruits may identify these other potential biological effects that may be useful in the prevention of disease. Fruits of the analyzed apple varieties should preferably be consumed fresh because after the apples were stored in the refrigerator for 1 month, indicators of antioxidant activity (22 mg/g in Surkhseb apples) and levels of almost all biologically active substances (tota) levels of tannins (14 mg/g), phenolcarboxylic acids (9 mg/g) (including chlorogenic acid: 250 μg/g) and catechin L-epicatechin (30 µg/g) in Surkhseb apples decreased. This study highlights the importance of conserving local, unique varieties of major worldwide crop plants because they may unearth novel combinations of compounds beneficial to humanity.

The complete mitogenome of Alternaria tenuissima (Kunze) Wiltshire 1933 (Pleosporaceae), a fungus causing apple leaf blotch disease

Alternaria tenuissima (Kunze) Wiltshire 1933 is a plant pathogenic fungus mainly causing leaf blotch disease. Here, we de novo assembled mitochondrial genome of A. tenuissima isolate AT-1224. The total mitogenome size is 57,475 bp with 29.00% G + C content. The genome contained 12 coding genes and 15 hypothetical proteins, 34 transfer RNA (tRNA) genes and 2 ribosomal RNA (rRNA). There are 227 SSR repeats, range from 2 to 4 base pairs, most five repeats were AT (144), AAT (54), AG (33), AC (13) and AAG (5). The results also found 13 tandem repeats (>100 bp), the largest repeat were forward 2 times located from 13,405 to 20,024 bp and 25,549 to 32,168 bp. Phylogenetic analysis based on 17 species complete mitogenomes indicated that A. tenuissima mitogenome was closest to 2 species, A. solani and A. alternata, sister clade to 6 species, representing Curvularia clavate, Exserohilum rostratum, Exserohilum turcicum, Bipolaris cookie, Bipolaris oryzae and Bipolaris sorokiniana. Further analysis among common fungus in local apple orchards using mitochondrial protein-coding genes revealed A. tenuissima were closing to 2 Alternaria fungi and a fungus representing Phoma sp. These results provide a basic reference for identification and evolution studies of A. tenuissima on apple trees.

Apple Pomace as a Potential Source of Oxidative Stress-Protecting Dihydrochalcones.

Among fruits, the apple is unique for producing large amounts of the dihydrochalcone phloridzin, which, together with phloretin, its aglycone, is valuable to the pharmaceutical and food industries for its antidiabetic, antioxidant, and anticarcinogenic properties, as well as its use as a sweetener. We analysed the phloridzin concentration, total phenolic content, and antioxidant activity in the peel, flesh, seeds, juice, and pomace of 13 international and local apple varieties. In the unprocessed fruit, the seeds had the highest phloridzin content, while the highest total phenolic contents were mostly found in the peel. In processed samples, phloridzin and the total phenolic compounds especially were higher mostly in juice than in pomace. Moreover, the total phenolic content was much higher than the phloridzin content. Juice showed the highest antioxidant activity, followed by the peel and flesh. Across all samples, antioxidant activity did not directly correlate with phloridzin concentrations, suggesting that the antioxidant activity ascribed to phloridzin may need re-evaluation. In the Ferric Reducing Antioxidant Power (FRAP) assay, phloridzin only showed antioxidant activity at high concentrations when compared to its aglycone, phloretin. Considering the large amounts of apple juice produced by the juice industry, residual pomace is a promising source of phloridzin. For technical use, processing this phloridzin to phloretin would be advantageous.

Ecological and economic evaluation of modern systems for apple tree protection from codling moth

This work substantiates the transition to biorational systems of plantation protection using low-toxic preparations to ensure high-quality yields. Regularities in the development of codling moth in Krasnodar Krai are revealed. During the period of 2021–2023, a 30% increase in the expenditures on protective measures in horticultural organizations of Krasnodar Krai was established. As a result, the production costs grew by an average of 17%, decreasing the entire efficiency of fruit production. This explains the need to develop modern protection systems for perennial plantations. Differentiated approaches to apple-tree protection from pests (on the example of codling moth), which are based on application of low-toxic chemical and biorational preparations according to phytophage development stages, are reviewed. An integrated system for protection of industrial fruit plantations in the Krasnodar Krai against coddling moth is proposed. The advantages of the proposed system over the existing approaches that apply highly toxic chemicals are described. These relate to the possibility of introducing flexible changes in protective measures in accordance with phytosanitary characteristics of orchards, including activation of local apple varieties and use of agrotechnical and biological methods based on toxicological monitoring. An ecological and economic evaluation of the integrated system of fruit plantation protection from codling moth is provided. This system enables a reduction in the background pesticide content in food chains (a 2-fold and 5-fold decrease in soils and fruits, respectively), a 1.3-fold reduction in pesticide load, the preservation of yield by more than 98% while complying with the regulations of ecological agrocenosis safety regulations, a 1.5-fold reduction in production costs, and a 10.5% increase in the product profitability.

Self-(in)compatibility in Tunisian apple accessions [Malus domestica. Borkh]: S-genotypes identification and pollen tube growth analysis.

Self-incompatibility studies have revealed a potential use of Tunisian apple resources for crop improvement and modern breeding programs and a likely correlation between the pollen tube growth and flowering period. Apples [Malus domestica. Borkh] exhibit an S-RNase-based gametophytic self-incompatibility (GSI) system. Four primer combinations were used to S-genotype eighteen Tunisian local apple accessions and twelve introduced accessions that served as references. Within the Tunisian local accessions, S2, S3, S7, and S28 S-alleles were the most frequent and were assigned to 14 S-genotypes; among them, S7S28, S3S7, S2S5, and S2S3 were the most abundant. PCA plot showed that population structuring was affected by the S-alleles frequencies and revealed a modern origin of the Tunisian varieties rather than being ancient ones. Nonetheless, the results obtained with 17 SSR markers showed a separate grouping of local Tunisian accessions that calls into question the hypothesis discussed. Pollination experiments showed that the pollen started to germinate within 24h of pollination but 48h after pollination in the "El Fessi" accession. The first pollen tubes arrived in the styles within 36h of pollination in two early flowering accessions known as "Arbi" and "Bokri", and after 72h of pollination in late flowering "El Fessi" and 48h after pollination in remaining accessions. The first pollen tube arrests were observed in accessions "Arbi" and "Bokri" within 84h of pollination, within 108h of pollination in "El Fessi" and within 108h of pollination in remaining accessions. In the apple accession called "Boutabgaya," the pollen tubes reached the base of the style within 120h of pollination without being aborted. Nevertheless, the self-compatible nature of "Boutabgaya" needs more studies to be confirmed. However, our results revealed the malfunction of the female component of the GSI in this accession. To conclude, this work paved the path for further studies to enhance the insight (i) into the relation between the flowering period and the pollen tube growth, (ii) self-compatible nature of "Boutabgaya", and (iii) the origin of the Tunisian apple.

Eco-physiological behaviors of some apple genotypes (Malus x domestica Borkh.) in the hot-and-dry climate of an inner area of Southern Italy

The Italian internal areas are distant from the main trade flows and service centers, but have important environmental and cultural resources. The Italian “National Strategy for Inner Areas” represents a novel policy aimed at contrast the abandon of these territories by supporting multiple activities aimed at stimulating economic development and promoting territorial cohesion. The condition of marginality offers the chance to pursue economic development according to the principles of sustainability. These internal areas are often distinguished by a purely rural vocation. Genotypes of fruit crops traditionally grown in inland areas cope often with difficult climatic conditions and low-input farming techniques, showing generally a good tolerance to abiotic tresses. Exploring their eco-physiological behaviors in response to the agri-environmental context is useful for identifying crops capable of stimulating the recovery and expansion of a sustainable agriculture system in inland areas. The present work reports some results of a research conducted on three traditional local apple genotypes grown in an internal hot-arid summer area of Southern Italy, evaluating their water status and the intensity of leaf gas exchange compared to those of a well-known “standard” cultivar, in a hot, dry summer period. The local genotypes tested in this case study proved to be more eco-physiologically performing. The experiment allowed to estimate their probable relative eco-physiological advantages compared to the “standard” apple genotype taken as reference.

STUDY OF GENETIC DIVERSITY OF APPLE TREE IN THE GUBIN REGION OF AZERBAIJAN

The work is devoted to the study of the genetic diversity of local apple varieties common in the Guba region of Azerbaijan. The purpose of this work was to study biomorphological characteristics, identify them based on molecular markers and determine the degree of genetic relationship between species and forms of apple varieties. Based on DNA analysis of apple tree varieties from the collection, patterns of distribution of genes that control the long-term preservation of fruits in apple tree varieties and forms were identified. Unique genotypes carrying rare alleles at microsatellite loci were identified.

Anti-methicillin resistant Staphylococcus aureus (MRSA) activity of fermented apple peels kombucha and their chemical content

The production of kombucha using local apple peels is expected to reduce the production of apple peel waste while increasing the nutritional and functional value of kombucha products. This study aimed to determine the active compounds and antibacterial activity of kombucha apple peels against MRSA (Methicillin Resistant Staphylococcus aureus). This research was carried out experimentally in a completely randomised design with two factors: the apple varieties (Anna, Manalagi, and Romebeauty) and the concentration of the apple peel substrate (2.5%, 7.5% and 12.5%). The analyses comprised phytochemical screening and antimicrobial activity testing, both qualitative and quantitative. The results showed that the kombucha apple peel contains tannins, saponins, flavonoids, polyphenols, and organic acids. The average total phenolic, total acid, and antibacterial activities of Kombucha apple peels were significantly (α≤0.05) differently affected by apple cultivar and substrate concentration. Antimicrobial activity against MRSA showed a range of weak to moderate inhibition, with the highest inhibition zone diameter value of 6.58 ± 0.52 mm in the Anna variety treatment at 12.5% substrate concentration. The MIC of the best treated kombucha was found at a concentration of 85%, while the MBC could not be determined.

Analysis of Methanol Content in Different Varieties of Traditionally Fermented Alcohol Found in Chandannath Municipality of Jumla District, Nepal

Background: Alcohol poisoning associated with traditionally fermented alcoholic beverages have been reported in Nepal with the constituents of these beverages not being quantified usually. In traditionally fermented alcoholic beverages, methanol, due to its cheaper cost and similar physiochemical properties with ethanol, is adulterated most commonly and readily. The objective of the present study was to quantify four different varieties of traditionally fermented alcoholic beverages available in Chandannath, Jumla for methanol level.Methods: The present study is a cross-sectional study in which four different types of traditionally fermented alcoholic beverages were collected from Chandannath, Jumla and they were analyzed for methanol content. From Chandannath municipality, the ward number two was selected for collection of samples. Further, from this ward, four different households regularly involved in brewing local alcohol were also randomly selected. These households belonged to three different ethnic groups (Indo-Aryan, Tibeto-Burman and Newar) and these samples were chhyang (sample- 1), local raksi (sample- 2), nigar (sample- 3) and local apple cider (sample- 4). In air tight containers, the samples were sealed and transported to Zest laboratory, Bhaktapur, Nepal for quantification of methanol using Gas Chromatography.Results: The residents in half of these four households belonged to the Tibeto-Burman ethnic groups. Methanol was detected in two samples among the four analyzed beverages. These samples, sample- 2 and sample- 4, on quantification showed the concentrations of 10.050ppm and 13.721ppm of methanol respectively. Conclusion: Among four samples of locally brewed alcoholic beverages, methanol was detected in two samples, but at a concentration below the level that would be considered toxic. This finding emphasizes the importance of conducting larger-scale quantification of traditionally fermented alcohol to mitigate the various health risks associated with its potential toxicity, as these beverages are currently not being quantified.

Exploring Wild and Local Fruits as Sources of Promising Biocontrol Agents against Alternaria spp. in Apples

Biological control agents (BCAs) are a promising option for managing postharvest diseases. Their environmentally friendly nature makes them valuable for sustainable and eco-friendly postharvest disease management. This study evaluated the antagonistic potential of epiphytic yeasts isolated from a local apple genotype known as “Niğde Elması” and a range of wild fruits: rosehip, hawthorn, and wild pear. There were 375 yeast isolates obtained and screened in vitro and in vivo. Initially selected were 32 isolates able to inhibit the growth of Alternaria alternata mycelia in the in vitro experiments and identified using molecular methods as candidate BCAs. These isolates were identified as Aureobasidium pullulans using sequence analysis of the internal transcribed spacer (ITS) and the translation elongation factor EF-1α gene (EF1α). Based on two rounds of in vivo screening, four isolates were subsequently selected for their capability to control the infection of apple fruits under high inoculum pressure. Finally, their volatile and non-volatile antimicrobial activity was tested against Alternaria spp. These findings showed how wild fruits and a local apple genotype could represent a promising source for new BCA isolation. However, further studies are needed to reveal the mechanisms of action of these putative BCAs for application during the postharvest processing and storage of apples.

A Study of Apple Orchards Extraction in the Zhaotong Region Based on Sentinel Images and Improved Spectral Angle Features

Zhaotong City in Yunnan Province is one of the largest apple growing bases in China. However, the terrain of Zhaotong City is complicated, and the rainy weather is more frequent, which brings difficulties to the identification of apple orchards by remote sensing. In this paper, an improved spectral angle feature is proposed by combining the Spectral Angle Mapper and Sentinel-1 data. Based on the Google Earth Engine and Sentinel image, a random forest classifier was used to extract apple orchards in the Ganhe Reservoir area, Zhaoyang District, Zhaotong City, which provides a theoretical basis for extracting the spatial distribution and sustainable development of the local apple industry. The classification results show that the improved spectral angle characteristics can improve the overall accuracy and F1 score of apple orchards. The RGB band combined with NDVI, GLCM, and improved spectral angle features obtained the most favorable results, and the F1 score and overall accuracy were 88.89% and 84.44%, respectively, which proved the reliability of the method in identifying apple orchards in Zhaotong City.

Quantification of phytochemical and antioxidant properties of aqueous apple extracts from the high atlas mountains in Morocco and their anti-inflammatory effect on Wistar rats

Apples are a valuable source of health-promoting polyphenols. However, a considerable variation in the polyphenol contents and bioactivities may exist among different apples from different origins. As the apples derived from traditional agriculture in the Moroccan High Atlas Mountains (above 2000 m of altitude) are less explored. This study aimed to investigate the polyphenol contents, antioxidant and anti-inflammatory activities of aqueous extracts derived from five varieties of apples from the High Atlas Mountains in Morocco compared to two imported European varieties of apples. The content of phenol acids, flavonoids, tannins, and reducing sugars were spectrophotometrically measured. Ferric reducing antioxidant power (FRAP), radical scavenging activity (RSA), and total antioxidant capacity (TAC) were assessed in vitro. The anti-inflammatory activity was conducted using paw edema induced by sub-plantar injection of formalin (0.05 mL, 4%) in rats. The results showed that local apples, particularly the Imilchil extract, contained the highest content of polyphenols (9.11 ± 0.36 GAE mg/gE), flavonoids (7.59 ± 0.23 RE mg/gE), and tannins (2.94 ± 0.05 CE mg/gE) but lower content of reducing sugars. Among all the tested extracts, Imilchil also exhibited the highest antioxidant activity in 1,1-diphenyl-2-picrylhydrazyl RSA (IC50= 1.12 ± 0.02 mg/mL), FRAP (110.55 ± 1.55 Fe2+E mMol/gE) and TAC (731.48 ± 3.02 AAE µg/gE) when compared with imported apples (Alpe and Golden), that have the lowest antioxidant activities in RSA (IC50 3.46 ± 0.12 and 3.92 ± 0.10 mg/ml), FRAP (18.30 ±.08 and 21.27 ± 0.99 Fe2+E mMol/gE) and TAC assays (133.22 ± 6.42 and 225.06 ± 2.88 AAE µg/gE), respectively. The administration of a single dose (500 mg/kg BW) of local apple extracts significantly inhibited about 54.77% of paw edema, while the imported apples produced about 30.60%. It is concluded that apples from the Moroccan High Atlas Mountains could be a rich source of natural polyphenols with anti-inflammatory and antioxidant potentialities.

Detecting Locus of Resistance to Scab in Local Apple Varieties in Uzbekistan Using Molecular Genetic Markers

The apple tree (Malus sp.) is the most cultivated plant in the world. Apple orchards cover a large area. scab (Venturia inaequalis) causes significant damage to the economies of many countries that are engaged in the production of apple trees. In Uzbekistan, most of the orchards are apple orchards. The present study includes a molecular genetic analysis of the resistance of local apple cultivars to pathogens Venturia inaequalis in local apple cultivars grown in Uzbekistan and the results of identification of resistance genes. The paper presents the results of molecular genetic analysis of the combination of scab resistance genes (Vf, Vfa1, Vfa2) found in 15% of samples. In 58.7% of the studied samples, a “high level of resistance” to scab was revealed.

The occurrence of entomopathogenic fungi in apple orchards and their biocontrol potential against Eriosoma lanigerum

Eriosoma lanigerum (Hausmann) (Hemiptera: Aphididae), woolly apple aphid (WAA) is an important pest on apples globally and a key pest of apple production in South Africa. The aphid has developed some level of resistance against several chemical insecticides. Entomopathogenic fungi (EPF) have been identified as promising biological control agents against a wide array of insect pests. The main aim of this study was to conduct a survey in local apple orchards in the Western Cape province for EPF and to use isolates to test the susceptibility of WAA under optimum laboratory conditions. Soil samples were collected from apple orchards and EPF, baited and isolated using larvae of Galleria mellonella and Tenebrio molitor. Six EPF species: Beauveria bassiana, Cordyceps fumosorosea, Metarhizium brunneum, M. pinghaense, M. robertsii and Purpureocillium lilacinum were identified from the soil samples. The results from bioassays showed that Metarhizium robertsii and M. pinghaense isolates were the most effective with an average percentage mortality of > 90%. Metarhizium brunneum also proved to be effective when used against the insect with an average percentage mortality of > 80%, while B. bassiana and C. fumosorosea were the least effective with average percentage mortality of 52% and 48%, respectively. The LT50 and LT90 of M. robertsii (2.12; 4.19) and M. pinghaense (2.05; 4.45) showed to require similar mortality time in days of E. lanigerum. The results obtained in the study have provided an insight into the diversity of EPF species across apple orchards of the Western Cape and shown the efficacy of the Metarhizium isolates as potential biological control agents of the WAA.

Autochthonous Apple Cultivars from the Campania Region (Southern Italy): Bio-Agronomic and Qualitative Traits

Apple (Malus × domestica Borkh.) is an important fruit crop widely spread in the cold and mild climates of temperate regions in the world, with more than 93 million tons harvested worldwide in 2021. The object of this work was to analyze thirty-one local apple cultivars of the Campania region (Southern Italy) using agronomic, morphological (UPOV descriptors) and physicochemical (solid soluble content, texture, pH and titratable acidity, skin color, Young's modulus and browning index) traits. UPOV descriptors highlighted similarities and differences among apple cultivars with a depth phenotypic characterization. Apple cultivars showed significant differences in fruit weight (31.3-236.02 g) and physicochemical trait ranging from 8.0 to 14.64° Brix for solid soluble content, 2.34-10.38 g malic acid L-1 for titratable acidity, and 15-40% for browning index. Furthermore, different percentages in apple shape and skin color have been detected. Similarities among the cultivars based on their bio-agronomic and qualitative traits have been evaluated by cluster analyses and principal component analyses. This apple germplasm collection represents an irreplaceable genetic resource with considerable morphological and pomological variabilities among several cultivars. Nowadays, some local cultivars, widespread only in restricted geographical areas, could be reintroduced in cultivation contribution to improving the diversity of our diets and contemporary to preserve knowledge on traditional agricultural systems.

Development and Evaluation of a Small-Scale Apple Sorting Machine Equipped with a Smart Vision System

One of the most important matters in international trades for many local apple industries and auctions is accurate fruit quality classification. Defect recognition is a key in online computer-assisted apple sorting machines. Because of the cavity structure of the stem and calyx regions, the system tends to mistakenly treat them as true defects. Furthermore, there is no small-scale sorting machine with a smart vision system for apple quality classification where it is needed. Thus, the current study focuses on a highly accurate and feasible methodology for stem and calyx recognition based on Niblack thresholding and a machine learning technique using k-nearest neighbor (k-NN) classifiers associated with a locally designed small-scale apple sorting machine. To find an appropriate mode, the effects of different numbers of k and metric distances on stem and calyx region detection were evaluated. Results showed the effectiveness of the value of k and Euclidean distances in recognition accuracy. It is found that the 5-nearest neighbor classifier and the Euclidean distance using 80 training samples produced the best accuracy rates, at 100% for stem and 97.5% for calyx. The significance of the result is very promising in fabricating an advanced small-scale and low-cost sorting machine with a high accuracy for the horticultural industry.

Rationale for choosing optimal yeast races for the production of sparkling cider

The article considers issues related to identifying the most suitable varieties of apples of technical maturity of summer and autumn – winter varieties growing in the Republic of Adygea and the possibility of their use in the technological process of cider production using champagne yeast races. Local apples are in demand both in food and processing industries and among the population. This is due to their unique chemical composition. Technological maturity of experimental varieties of apples have been studied and assessed for a number of technological indicators. The article presents a comparative description of summer and autumn-winter varieties of apples that have reached technological maturity. The study has revealed that autumn-winter varieties of apples are the best for the production of cider. The possibility of using champagne yeast races in the technology of sparkling cider production has been investigated and proved. A significant influence of yeast races on the formation of aroma and taste has been established. According to the literature data, various biochemical processes occur during the fermentation process with a change in the main components of the wort, the formation and synthesis of new compounds that are involved in the formation of aroma and taste. Apple wort fermented with 7–10 Champagne race differed from the control sample and the Novotsimlyanskaya-3 race in a more harmonious taste, fresh and expressive aroma.At present, the main task of the agro-industrial complex of the Russian Federation is to use of local raw materials for the development of new technologies that meet the needs of the population. The results of the experiment have shown the possibility of using autumn-winter varieties of apples growing in the Republic of Armenia in the cider production, and also has made it possible to justify the use of champagne yeast races in this technology to obtain wine materials with high organoleptic characteristics.These studies allow to improve the technological process of cider production.
