Climate change, urbanization, urban population growth and the globalization of unhealthy diets can lead to serious food security challenges. Rare fruit plants have a number of valuable consumer qualities and are resistant to abiotic and biotic environmental factors, high decorative qualities, versatile and wide potential for use in fruit growing, breeding and gardening. These species can serve as sources of biologically active substances. The aim of our research was to study the ecological and biological characteristics of rare fruit plants of the Rosaceae family of the gene pool of the VNIISPK arboretum for the effective use of the potential of species biodiversity in breeding. The objects of study were 14 species. The studies were carried out over three years (2018 - 2020). Based on the results of a comprehensive ecological and biological assessment of 14 species of rare fruit plants of the Rosaceae family of the gene pool of the VNIISPK arboretum, 8 promising adaptive genotypes were identified, which are recommended to be used as genetic sources for breeding for obtaining varieties with a complex of economically valuable characteristics. These are Chaenomeles Maulei, Crataegus submollis, Amelanchier Canadensis, Amelanchier ovalis, Mespilus germanica, Padus virginiana, Padus Maackii and Malus prunifolia. Malus niedzwetzkyana and Sorbus aria are recommended as sources of pest resistance.

The paper deals with the peculiarities of the biological characteristics of the most important fruit crops of temperate climates - apple and pear (Rosaceae family, subfamily Maloideae), taking into account the world, national and regional cultivation. Both cultures are characterized by significant food and commodity value, have some differences in the chemical composition of the fruit, including the leading components of the mass and biologically active substances, which determine the peculiarities of their use in the human diet. In both global and national fruit-growing, pears play a secondary role compared to apple, giving way to the number of varieties, the volume of production and the areas occupied. Based on the analysis of available statistical data of the FAO database, the dynamics of changes from 1990 to 2016 of the world production of apple and pear fruits with visualization on the continents, identifying world leaders and major trends are considered. For the USSR (from 1962 to 1990) and in Russian Federation (from 1992 to 2016) the paper presents a picture of changes in the volume of fruit production, discusses the status of fruit production in the country. The features of the historical development and current state of fruit growing in the Samara Region and prospects are discussed.

The fruit Malus prunifolia (Malus micromalus Mak.), which belongs to the Rosaceae family, grows mostly in the upper-middle reaches of the Yellow River area. It has long been popular as a fruit commodity and as a natural remedy. Its main biologically active components include vitamin C, phenolics, flavonoids, polysaccharides, and triterpenic acids. Recent phytochemical studies on the fruit have shed some light on its biological activities, such as anticancer, immunomodulatory, antioxidant, immunostimulating, hepatoprotective, and gastrointestinal protective activities. A stronger focus on clinical studies and phytochemical characterization of the fruit will be essential for future research efforts. This minireview could be useful for predicting its other medicinal uses and its potential drug or food interactions, and it could be beneficial for people living in areas where the fruit is endemic and where healthcare resources are scarce.

Rosa x damascena Herrm. represents one of the most popular and important plants of the Rosaceae family. For ages, rose oil, rose water and extracts from its flowers were used in perfumery, cosmetics, aromatherapy, and medicine due to diverse pharmacological efficacy. Nowadays, special attention is paid to the valorization of wastes from the rose oil industry in order to fully recover potent biologically active compounds. The present study describes in detail the microstructural features of the flower petals and provides data on chemical composition and biological potency of the aqueous extract of rose oil waste from the R. damascena Georgian cultivar. Up to 25 constituents were detected by HPLC-MS in the extract, and the content of total flavonoids in the extract reaches 2.29%. Amongst them hyperoside is dominating, which content is not less than 1%. Pharmacological evaluation of the extract on "Hot plate" and carrageenan-induced oedema models in mice revealed analgesic (42%) and anti-inflammatory (67%) effects of the extract. As well, the extract revealed antiplasmodial activity against Plasmodium falciparum (3D7) strain (IC50 =20.31 µg/mL)

Juice «vitgrass» made from green wheat sprouts is a valuable biologically active product that has a stimulating effect on the physiological state of a person. Hydroponically grown raw materials for juice production contain proteins, fats, carbohydrates, a large group of vitamins, macro- and microelements, antioxidants, enzymes and other substances. As a part of health programs, the use of this juice is recommended for overweight people to optimize the metabolic processes of the macroorganism. A healthy lifestyle involves reducing the negative impact of environmental factors, including diet correction, on the microbiota of the gastrointestinal tract. The cumulative biological assessment of wheatgrass juice should take into account the results of its effect on the indigenous microflora. Lacto- and bifidobacteria, including industrial strains for the manufacture of probiotic preparations, represent an adequate model for studying the bacteriotropic effect of any plant-based product. The experimental results indicate a pronounced stimulating effect of juice from green wheat sprouts on the growth parameters of probiotic bacterial cultures. Strains of lacto- and bifidobacteria when cultivated under conditions of maximum limitation of nutrients in the composition of the "poor" nutrient medium with the addition of "Vitgrass" juice reacted with an increase in the level of accumulation of cell biomass and a higher activity of acid formation in comparison with the control. The analysis of the results obtained makes it possible to estimate the magnitude of the effects of stimulation in relation to both bacterial cultures as quite comparable, taking into account the known intersstrain differences in growth parameters and their biochemical aspects. This is confirmed by an almost similar increased level of carbohydrate utilization in both variants of culture liquids in the presence of juice. The potential of the positive bacteriotropic activity of "Vitgrass" juice in relation to the representatives of the indigenous microflora can be realized in different ways. It seems expedient to use the product from green wheat sprouts more widely as part of programs for the complex health improvement of the macroorganism, including the prevention and correction of dysbiotic conditions.

Introduction. Plants are a valuable source of biologically active compounds, including antioxidants, which could prevent the development of oxidative stress. The members of Rosaceae family such as Sorbus aucuparia L. and Cydonia oblonga Mill. are the examples of plants contained antioxidants. Aim. The aim of the study was to evaluate the antioxidant potential of leaves and fruits extracts of rowan and quince, taking into account influence of the extrahent as well as extraction method on this activity. Material and methods. The extracts were obtained by classic extraction methods – shaking and extraction in Soxhlet apparatus. Methanol, acetone as well as 70 and 96% (v/v) ethanol were used as solvents. Antioxidant activity was estimated by DPPH, FRAP, Folin-Ciocalteu (F-C) and ABTS methods. Results. The highest antioxidant activity was found in leaf extracts of both plants. In most cases, rowan extracts showed higher potential than appropriate extracts of quince. The most effective extraction method was extraction in Soxhlet apparatus using methanol (in case of rowan and quince) as well as 96% (v/v) ethanol (quince) and 70% (v/v) ethanol (rowan). The highest results were obtained with FRAP method, whereas the lowest – with DPPH. Conclusions. The presented in vitro results confirmed, that the leaves and fruits extracts of selected plants belonging to the Rosaceae family showed antioxidant activity and could be applied in various industry branches.

Smallholder farmers across Zimbabwe have been facing a problem of food insecurity because of climate-induced droughts and lack of effective use of irrigation schemes. Rainfall patterns in the country have become more unpredictable and inconsistent with the traditional farming seasons. Faced with such challenges, many smallholder farmers in Shurugwi district in the Midlands province of Zimbabwe adopted small-scale irrigation schemes to improve food security. The principal objectives of this study were to examine the status of the irrigation schemes in the district; analyse the need to rehabilitate small-scale irrigation schemes; assess the initiatives towards the revival of irrigation schemes; establish the benefits that can accrue to smallholder farmers from small-scale irrigation schemes and discuss challenges faced by smallholder farmers in the running of small-scale irrigation schemes in rural areas. This qualitative study employed literature and interviews to obtain data from 40 purposively selected participants. The direct observation method was used to compliment the interviews. The findings of the study were that small-scale rural irrigation schemes have the capacity to significantly transform the lives of rural farmers through earning increased reliable income from farming if institutional and capacity issues of the farmers are addressed. Furthermore, the study found that small-scale irrigation schemes can also be a panacea to food security challenges mainly faced by rural households. As such, the article concluded that irrigation schemes are fortress and antidote to the effects of climate change. The study calls for capacity promotion on technical skills for the farmers, the establishment of many new irrigation schemes and the rehabilitation of the existing small-scale irrigation schemes in the country as well as calling on the farmers to adopt climate-smart irrigation.

Abstract: Fruit flies are the main pests of fruit growing in Brazil. They have been managed predominantly with the use of insecticides applied as cover spray and or/as toxic baits. Currently, the trend of management strategies is toward the adoption of methods that cause the lowest environmental impact in large areas. In this context, biological control is an excellent option to be used together with other management strategies, such as sterile insects, because it leaves no residues, does not disturb nontarget pests, and can be permanent if the natural enemy establishes itself in the field. This review paper addresses the current knowledge on the biological control of fruit flies in Brazil, highlighting the great biodiversity of its natural enemies, especially parasitoids, its biology and ecology. The classical biological control programs in Brazil are also reported, from the introduction of Tetrastichus giffardianus (Hymenoptera: Eulophidae), in 1937, to control Ceratitis capitata (Diptera: Tephritidae), to that of Fopius arisanus (Hymenoptera: Braconidae), in 2012, to control Bactrocera carambolae (Diptera: Tephritidae). Finally, the obtained advances are pointed out, as well as the main bottlenecks and perspectives for the effective use of biological control programs against fruit flies.

The article highlights the main achievements, problems and directions of the further development of the landing stock of Ukraine, the prospects of scientific research of Institute of Animal breeding and Genetics nd. a. M.V.Zubets of the NAAS in the areas of breeding, genetics, biotechnology of reproduction and preservation of the gene pool of farm animals. Institute is the initiator of four dairy herds (Ukrainian Red-and-White, Black-and-White, Red and Brown dairy bread) and four meat (Ukrainian, Volyn, Polissya and Southern meat) breeds of cattle. Its employees carry out scientific support of regional livestock development programs, development of systems for the creation and management of commercial herds of dairy and beef cattle, which contributes to solving the global food problem, and to ensure the nutrition security of Ukrainian population. The newly created Ukrainian Black-and-White, Red-and-White and Red dairy breeds for the predominantly intra-species breeding improvement and limited access to the gene pool of the Holstein breeding breed should remain the main areas of the breeding improvement of domestic dairy cattle breeding. The existing breeding system in cattle in Ukraine does not meet international standards and practically does not work in a complex way, and it threatens the final destruction of domestic breeding livestock, a significant dependence of the country on the import of breeding resources. To solve the problem, a new structure of the breeding service with a clear definition of the organizational basis for the management of tribal affairs and functional responsibilities of the subjects of its implementation was proposed, the formation of a centralized national information base for the identification, registration, origin and performance of animals, the keeping of state books of breeding animals as the basis estimation of their genetic value, and its realization is entrusted to the state enterprise created at the institute on Main scientific-production informational-elective center in livestock. Promising areas for farm animal breeding research are grouped into gene identification and the degree of development of quantitative attributes (QTL), early prediction and evaluation of breeding value of animals using markers (MAS). Research on molecular genetics is aimed at improving genetic analysis methods at individual and population levels, monitoring herds of cattle according to different types of genetic markers. Genetic systems for testing animals in 9 loci quantitative attributes, which are involved in the formation of qualitative indicators of dairy and meat productivity. A work is under way to test animals for the polymorphism of the BoLA-DRB3 gene of the major histocompatibility complex in animal populations for resistance to or susceptibility to mastitis. Biotechnology research focuses on reproductive biology methods, first of all, manipulations with gametes of farm animals, in vitro fertilization of pre-matured oocytes of cows and pigs, and others. The technology of obtaining oocyte cumulus complexes from ovaries of animals, the conditions of their storage, cultivation and fertilization out of the organism, which allows receiving a much larger number of embryos for both scientific and practical purposes, is developed. A separate direction is the work to improve the biotechnological methods of reproduction of farm animals using nanomaterials. It is based on the application in cryopreservation and sperm production of sperm and ovules of various variants of biologically active substances that are applied to highly dispersed silica molecules (albumin of blood serum of cattle, N-acetylneuramic acid – UFS / BSA / NANA). In order to monitor and preserve the diversity of genetic resources of agricultural animals in Ukraine, a complex of works under NAAS scientific program "System of work in populations and preservation of biological diversity of genetic resources of farm animals" ("Preservation of gene pool of breeds") with a coordination center on the basis of Institute of Animal breeding and Genetics nd. a. M.V.Zubets of NAAS. The research resulted in the development of the Program for the preservation of the gene pool of local and endangered breeds of farm animals in Ukraine for 2017–2025, in which the methodological bases for preservation of the gene pool were generalized, animal breeds were classified according to the criteria of risk, the minimum sizes of herds (real and virtual) of faulting species were substantiated, the minimum the size of subsidies for the proper functioning of small-numbered breeds, general methodological approaches to assessing the specificity of genetic resources are specified.
