Creation of new varieties that combine a complex of valuable traits, incl. the marketability and quality of fruits for updating the assortment of sweet cherry is an urgent direction of breeding research. The paper presents the results of a long-term work on the assessment of 12 varieties of sweet cherries of domestic and foreign breeding according to the main parameters of marketability and quality of fruits. The studies were carried out in 2015–2020 on the basis of the «Tsentralnoye» experimental production farm of the North Caucasian Federal Scientific Center of Horticulture, Viticulture, Winemaking. As a result of regional breeding and long-term variety study sweet cherry varieties of local breeding (Alaya, Volshebnitsa, Chernie glaza) and introduced varieties (Anonce, Vasilisa, Kroupnoplodnaya, Sweet Heart, Skina) with larger fruits (fruit weight of 8.5–12.0 g) were identified. These varieties correspond to world marketability standards. Varieties with high biochemical parameters have been revealed: vitamin C (10.9–13.0 mg/100 g) Volshebnitsa, Podarok leta, Anonce; vitamin P (81.6–116.0 mg/100 g) Volshebnitsa, Podarok leta, Kroupnoplodnaya; anthocyanins (213.5–390.0 mg/100 g) Madonna, Chernie glaza; sugars (14.2–15.2 %) Alaya, Volshebnitsa, Podarok leta; soluble solids (19.8–22.8 %) Alaya and Volshebnitsa. A greatest variation in parameters (Cv = 60 %) was noted in the number of anthocyanins from 87.0 in the Volshebnitsa variety to 390.0 mg/100 g in the Madonna variety. At the same time, the supposed direct correlation between the ripening period and the accumulation of sugars (R2 = 0.083) and dry matter (R2 = 0.107) was not revealed, due primarily to the varietal specifics and year conditions. For modern technologies of the production of high-quality cherry products in the south of the country, domestic varieties Krasnaya devitsa, Volshebnitsa, Alaya, introduced varieties Anonce, Kroupnoplodnaya, Sweet Heart and Skina, stably bearing fruit under stress conditions, with a yield of 20.0 t/ha with a planting scheme 5.3 m, high marketable and taste qualities were suggested. Super early ripening cherry variety Madonna was recommended to expand the regional cherry conveyor.

The main goal of breeding and seed-growing work with perennial grasses is the creation and reproduction of intensive varieties that are distinguished by high productivity, adaptability, and resistance to adverse factors. The tasks of varietal seed production of perennial grasses in the taiga zone include the preservation of biological and economically useful properties inherent in the variety during its reproduction; ensuring timely implementation of variety change and variety renewal; accelerated multiplication of seeds of new varieties. It is important to cultivate each crop according to modern scientifically based varietal technologies that are developed for the conditions of the region. To create highly productive seed herbage and successful harvesting, it is necessary to take into account the biological characteristics of species and varieties. The choice of seed farming methods is determined by the ability of populations to retain their valuable properties in the process of seed reproduction. When developing promising methods of seed production of new generation varieties, it is necessary to study the reaction of plants to stressful phenomena and develop agrotechnical methods that allow plants to adapt to them with a minimum decrease in seed productivity. The development of seed production of perennial cereal grasses in the extreme soil and climatic conditions of the taiga zone contributes to the growth and stabilization of the gross harvest of seeds with high sowing qualities. The article presents the main results for 2015-2019. on perennial cereal grasses in the Narym Department of Breeding and Seed Production of the Siberian Research Institute of Agriculture and Technology - a branch of the SFNCA RAS. Seed growing is carried out according to the traditional scheme. Due to adaptive varieties, the agroecological zoning of seed production is being improved. The aim of this work is to summarize the results of seed production on perennial grasses in the taiga zone of the Tomsk region.

Relevance and methods. For the production of chicory seeds, care must be taken not only to obtain a high-grade source material, i.e. varietal seeds and masterbatch root crops, but also to store the resulting root crops in winter with minimal losses. The main requirement for growing mother chicory root crops is the placement of crops on fertile soils that are clean of weeds. Installed. That on podzolized loams the best dose of mineral fertilizers for this crop is N45P120K60, where an increased dose of superphosphate increases the yield and rootability of Queen cells, increases seed productivity for the second year. Materials and methods. The purpose of this work is to analyze the safety of root crops of chicory root and the degree of their damage by root rot during winter storage in plastic bags in burts. The purpose of the study is to identify the best way to store the mother chicory root crops and the effect of reproduction on the rootability of root crops in winter. Questions of storage of the mother material of root chicory were studied in the laboratory of selection and seed production on the example of the Petrovsky variety in 2017-2019. The material for research was the families of chicory of the Petrovsky variety in the control and elite nursery. Results. The obtained data show that when evaluating and selecting families for the purpose of obtaining highly productive seed material, the safety of root crops in long-term winter storage should be taken into account. If its values are low, the entire family should be completely excluded from the process of primary seed production. In selection and seed-growing work, a mandatory component of the assessment should be the safety of root crops during long-term winter storage.

The main goal of the scientific institution was and remains to improve the assortment of fruit and berry crops for the development of domestic horticulture. Black currant breeding at VNIISPK was started by A.F Tamarova and continued by the doctor of agricultural Sciences T.P.Ogoltsova and doctor of agricultural Sciences S.D. Knyazev. A long-term breeding program has been developed. The main goals of the program are to create black currant cultivars with continuous resistance to diseases, first of all powdery mildew, as wells resistance to pests, i.e. bud mite. As a result of the long-term work, over 40 black currant cultivars have been developed, 14 of them are zoned. Red currant breeding was led by the candidate of agricultural Sciences L.V. Bayanova; since 2001 the work has been continued by the candidate of agricultural Sciences O.D. Golyaeva. ‘Heinemanns Rote Spӓtlese’, the descendant of R. multiflorum Kit., was involved in the red currant breeding for the first time in Russia. On its genetic basis, a series of late maturing cultivars with long and dense racemes was created. At the Institute, in total 21cultivars of red currants have been developed, 13 of them are zoned. At present, red currant cultivars make up 25.5% of the zoned assortment in Russia. The first research on gooseberries was stated by V.P. Semakin and A.F Tamarova; since 1992 the systematic gooseberry breeding has been carried out by the candidate of agricultural Sciences O.V. Kurashev. On the basis of Grossularia robusta, we have created gooseberry forms that are resistant to powdery mildew and leaf spots. These forms are highly productive, weakly thorned, having bush habit suitable for mechanized harvest. The result of breeding activities was the transfer of 6 gooseberry cultivars to State agricultural testing: ‘Solnechny Zaychik’, ‘Nekrasovsky’, ‘Yupiter’, ‘Zemlianichny’, ‘Moryachok’ and ‘Discovery’.

ABSTRACT Within the context of the work and achievements of James Croll, this paper reviews the records of direct observations of glacial landforms and sediments made by Charles Lyell, Archibald and James Geikie and James Croll himself, in order to evaluate their contributions to the sciences of glacial geology and Quaternary environmental change. The paper outlines the social and physical environment of Croll's youth and contrasts this with the status and experiences of Lyell and the Geikies. It also outlines the character and role of the ‘Glasgow School’ of geologists, who stimulated Croll's interest into the causes of climate change and directed his focus to the glacial and ‘interglacial’ deposits of central Scotland. Contributions are outlined in chronological order, drawing attention to: (i) Lyell's high-quality observations and interpretations of glacial features in Glen Clova and Strathmore and his subsequent rejection of the glacial theory in favour of processes attributed to floating icebergs; (ii) the significant impact of Archibald Geikie's 1863 paper on the ‘glacial drift of Scotland’, which firmly established the land-ice theory; (iii) the fact that, despite James Croll's inherent dislike of geology and fieldwork, he provided high-quality descriptions and interpretations of the landforms and sediments of central Scotland in order to test his theory of climate change; and (iv) the great communication skills of James Geikie, enhanced by contacts and evidence from around the world. It is concluded that whilst direct observations of glacial landforms and sediments were critical to the long-term development of the study of glaciation, the acceptance of this theory was dependent also upon the skills, personality and status of the Geikies and Croll, who developed and promoted the concepts. Sadly, the subsequent rejection of the land-ice concept by Lyell resulted in the same factors challenging the acceptance of the glacial theory.

AbstractThermal modification is an effective method that induces significant expansion of the antimicrobial properties and other valuable properties of chicken egg white lysozyme. In our latest research, a new innovative method of enzyme modification was developed, in which microwave radiation was used as an energy source to process liquid lysozyme concentrate (LLC). After modification, high-quality preparations were obtained. However, long-term storage in a concentrated form initiated various processes that caused darkening over time and could also lead to other significant changes to their structure and, consequently, to their functional properties. This necessitated multidirectional research to explain this phenomenon. This paper presents the results of research aimed at assessing the physicochemical changes in the properties of microwave-modified lysozyme in the form of a liquid concentrate after long-term storage under refrigeration conditions. The assessment also considered the conditions under the acidity of the modifying medium and the duration of the microwave modification. The analysis showed that the values of the basic parameters determining the quality and usefulness of the modified enzyme significantly improved during long-term storage of the preparations. The greatest changes were observed in the preparations modified for the longest time and in the most acidic environment (process time 260 s, pH 2.0), the number of oligomers under these conditions increased by 18% after 12 months of holding, and the surface hydrophobicity increased by as much as 31%. In addition, microbiological tests showed that the preparations of microwave-modified lysozyme had an effect on gram-positive bacteria as well as on gram-negative, and this effect was significantly enhanced after 12 months. The results confirm that LLC modification with microwave radiation is a highly efficient method to prepare high-quality and high utility potential lysozyme. Notably, an interesting and important phenomenon was the observation of the unconventional behaviour of the preparations during their long-term storage, which increased their utility potential significantly.

This paper describes the Passive microwave Neural network Precipitation Retrieval algorithm for climate applications (PNPR-CLIM), developed with funding from the Copernicus Climate Change Service (C3S), implemented by ECMWF on behalf of the European Union. The algorithm has been designed and developed to exploit the two cross-track scanning microwave radiometers, AMSU-B and MHS, towards the creation of a long-term (2000–2017) global precipitation climate data record (CDR) for the ECMWF Climate Data Store (CDS). The algorithm has been trained on an observational dataset built from one year of MHS and GPM-CO Dual-frequency Precipitation Radar (DPR) coincident observations. The dataset includes the Fundamental Climate Data Record (FCDR) of AMSU-B and MHS brightness temperatures, provided by the Fidelity and Uncertainty in Climate data records from Earth Observation (FIDUCEO) project, and the DPR-based surface precipitation rate estimates used as reference. The combined use of high quality, calibrated and harmonized long-term input data (provided by the FIDUCEO microwave brightness temperature Fundamental Climate Data Record) with the exploitation of the potential of neural networks (ability to learn and generalize) has made it possible to limit the use of ancillary model-derived environmental variables, thus reducing the model uncertainties’ influence on the PNPR-CLIM, which could compromise the accuracy of the estimates. The PNPR-CLIM estimated precipitation distribution is in good agreement with independent DPR-based estimates. A multiscale assessment of the algorithm’s performance is presented against high quality regional ground-based radar products and global precipitation datasets. The regional and global three-year (2015–2017) verification analysis shows that, despite the simplicity of the algorithm in terms of input variables and processing performance, the quality of PNPR-CLIM outperforms NASA GPROF in terms of rainfall detection, while in terms of rainfall quantification they are comparable. The global analysis evidences weaknesses at higher latitudes and in the winter at mid latitudes, mainly linked to the poorer quality of the precipitation retrieval in cold/dry conditions.
