Vegetables play a key role in food security and nutrition as the food system shifts from food quantity to dietary quality and health benefits. One of the main reasons for the low production and declining average yields of most vegetable crops is climate change. Important limiting factors in maintaining and increasing vegetable crop yields are rising temperatures, reduced water availability for irrigation, flooding and salinity. Under changing climatic conditions, crop failures, declining quality and increasing pest and disease problems are becoming commonplace and making vegetable production unprofitable. Since many physiological processes and enzyme activity are temperature dependent, they will be greatly affected. Drought and salinity are two important effects of rising temperatures that reduce vegetable crop yields. These impacts of climate change also affect the emergence of pests and diseases, host-pathogen interactions, distribution and ecology of insects, timing of emergence, migration to new locations, and their ability to overwinter, all of which become a major barrier to vegetable production. To mitigate the adverse effects of climate change on the productivity and quality of vegetable crops, sound adaptation strategies need to be developed. Emphasis should be placed on the development of production systems that improve water efficiency and are adapted to hot and dry conditions. Technological practices, such as mulching with crop residues and plastic materials, help maintain soil moisture. Excessive soil moisture due to heavy rains becomes a serious problem that can be solved by growing crops in raised beds. An effective way to solve these problems is to create genotypes that are resistant to high temperatures, moisture, salinity and resistance to climatic conditions, using traditional and non-traditional breeding methods, genomics, biotechnology, etc.

Relevance. The use of chemical mutagenesis on garlic is relevant for the creation of new forms with stable characteristics, better biochemical qualities, increased yield, for use in breeding practice.Results. The reaction of garlic treated with two chemical mutagens was evaluated: DES (diethyl sulfate) – 0.025; 0.05 and 0.1% (mutants 2, 3 and 4), as well as DMS (dimethyl sulfate) – 0.02; 0.04 and 0.08% solutions (mutants 5, 6 and 7). The aftereffect of chemical mutagens was noted with low and medium variability of signs in the second–fifth generation. According to the low variability of 1.6–9.4%, the height of plants (samples M 3 and 6), the number of leaves (M 5), the height of the false stem (M 3), the diameter of bulbs (M 6), as well as the length of leaves and the weight of bulbs samples M 3, 5 and 6 were distinguished. The effect of mutagens on morphometric signs of garlic were also tracked in the second generation (re-growing from air bulbs), where the parameters of low and medium variability of signs are marked. The majority of samples on 7 signs reflected a low variability of 5.5–10.0% and only 2 mutants showed an average variability of 11.4–16.4%: M 6 in plant height and false stem and M 3 in bulb diameter and yield. The correlation between their value in the 5th generation and in the 2nd generation also revealed strong direct and average connections. High heritability of h2 signs = 0.74–0.99 for DES preparations – 0.05%, VMI – 0.02 and 0.04%, was the most important indicator of the selection of valuable signs.

Relevance. Dagestan is a zone of prosperous agriculture, distinguished by the abundance of heat, sun and irrigation in the plain zone. Tomatoes occupy a special place among vegetable crops in the world, including in the Republic of Dagestan. Determinant varieties are now the most common in the production of tomatoes, especially in the open ground. The main areas of specialized cultivation of tomatoes in the open ground are concentrated in the Kizlyar and Derbent districts of plain Dagestan. In these areas, there are high average daily temperatures for the formation and ripening of tomato fruits in excess, which is favorably reflected in the overall productivity of the bushes. Whereas in the foothills of Dagestan, insufficient heat resources do not allow growing tomato varieties with a long growing season. In the foothill part of the republic there is a large labor-resource potential, vegetable growing, as a labor-intensive type of agribusiness, acts as a sphere of employment for a significant part of the rural population. The demand for tomato varieties with a short growing season in this part of the republic is great.Methods. The research was carried out on the basis of the Tersko Sulak subprovincion of the FGBNU of the FANC RD of the Kizlyar district. The soil of the experimental site is alluvial-meadow, medium-saline, medium loamy in mechanical composition. Agrotechnics is generally accepted in the Republic of Dagestan for tomato culture.Results. The method for the study was the new semi-stamp cultivars of FGBNU FNCO (VNIISSOK) selection: Fakel (counter), Blagodatny, Viking, Voskhod VNIISSOKa, Magnat, Severyanka, Sodruzhestvo, Perst, Patrice. According to the maturation dates, the samples were divided into three groups: very early – Severyanka, Blagodatny, Magnat, Voskhod VNIISSOK (97-100 days); early – Patrice, Viking, Perst (102-105 days); middle-early – Sodruzhestvo, Fakel (111-114 days). According to the type of bush, we have identified 5 ordinary and semi-lamb samples with a height of no more than 78 cm. Two samples had a height of 50-53 cm (Patrice, Perst) and an average fetal weight of 72 and 60 g. Three samples had a height of 70, 71, 72 cm (Voskhod VNIISSOKa, Blagodatny, Sodruzhestvo) and an average fetal weight of 107, 110, 130 g. According to the output of gross output, the best indicators were of the following varieties: Blagodatny – 86.3; Voskhod VNIISSOKa – 82.7; Sodruzhestvo – 77.6 t/ha; Patrice – 68.2 t/ha. The following grades had a high yield of marketable products: Voskhod VNIISSOKa, Patrice – 92%; Blagodatny – 91%; Perst – 90%. The varieties also have a relatively high dry matter index of 5.3-6.4%.

Relevance. The use of biological preparations in agricultural technology of agricultural crops contributes to the preservation of agrophytocenosis, reduces environmental pollution and has a positive effect on the growth and development of the plants themselves. In this regard, the determination of the effectiveness of the use of biological products in the presowing treatment of common bean seeds is relevant and timely.Materials and methods. In our study, we studied the effect of presowing treatment of common bean seeds with biological products: Polydon Bio Profi, Polydon Amino Mix, Polydon Aminomix, Alfastim on germination energy, germination, seed sprout size, number of roots and length of the root system. Three varieties were taken as objects of study: Athlete, Omichka, Sirenevaya.Results. A different effect of preparations on the time of seed germination was revealed. The average germination time in options 1-4 was higher than the control values for all varieties, i.e. drugs slowed down germination. The seeds of the tested varieties responded positively to treatment with Alfastim (option 5): the average germination time in Fizkulturnitsa and Sirenevaya decreased by 8.5 and 9.8%, in the Omichka variety by 45%, compared with the control. Among the tested varieties, it is necessary to single out the Sirenevaya variety, which has the highest germination energy (ES) from 90% to 100% and seed germination (VS) from 98-100% in all treatment options. The most effective treatment of the Omichka variety was in option 2 (EP-90%, germination rate 90%), the values exceeded the control by 5%. For all options, the germination energy of the Fizkulturnitsa variety ranged from 72 to 90%, germination from 73 to 93%. A positive effect of drugs on the germination of seeds of this variety was established. The defeat of bean seeds by mold fungi was noted. Seed damage is mild to moderate. Seed damage by mold fungi in the variants using Polydon Bio Profi was absent, or it was weak up to 3.3% for all tested varieties. Morphobiometric indicators of seedlings and their root system in all varieties developed more effectively on variants with the use of Polydon Bio Profi and Alfastim preparations, and their mixtures

Relevance. The main source of the natural pigment betanin is table beet, known for its medicinal and antioxidant properties, earliness and long shelf life, rich in bioactive compounds, minerals and vitamins. This research was induced by the lack of information required by breeders to increase betanin content in beet. Metabolite profiling is an effective way to assess the interplay between individual metabolites and betanin content in table beet.Materials and methods. The material was selected from the the N.I. Vavilov Institute of plant industry (VIR) collection. Biochemical analysis was based on VIR’s guidelines, and metabolite profiling on gas chromatography, coupled with mass spectrometry.Results. 17 free amino acids were found in the beet root extract. The greatest number of positive correlations with other amino acids (r˃0.72) was found in tyrosine, alanine and phenylalanine. A significant (r = –0.66) negative correlation was observed between betanin and succinic acid, credibly associated with betalamic acid. Sucrose predominated among carbohydrates (95%). Sucrose and maltose showed a weak positive correlation with betanin. Unsaturated oleic and saturated palmitic acids dominated among fatty acids (52% and 20% of total fatty acids, respectively). Earlier-ripening and cold-resistant table beet accessions showed a predominance of unsaturated fatty acids and lower betanin content.

The main source of the natural pigment betanin is table beet, known for its medicinal and antioxidant properties, earliness and long shelf life, rich in bioactive compounds, minerals and vitamins. This research was induced by the lack of information required by breeders to increase betanin content in beet. Metabolite profiling is an effective way to assess the interplay between individual metabolites and betanin content in table beet.Materials and methods. The material was selected from the the N.I. Vavilov Institute of plant industry (VIR) collection. Biochemical analysis was based on VIR’s guidelines, and metabolite profiling on gas chromatography, coupled with mass spectrometry.Results. 17 free amino acids were found in the beet root extract. The greatest number of positive correlations with other amino acids (r˃0.72) was found in tyrosine, alanine and phenylalanine. A significant (r = –0.66) negative correlation was observed between betanin and succinic acid, credibly associated with betalamic acid. Sucrose predominated among carbohydrates (95%). Sucrose and maltose showed a weak positive correlation with betanin. Unsaturated oleic and saturated palmitic acids dominated among fatty acids (52% and 20% of total fatty acids, respectively). Earlier-ripening and cold-resistant table beet accessions showed a predominance of unsaturated fatty acids and lower betanin content. The disclosed interactions are important for betanin-rich red beet breeding.","PeriodicalId":23570,"journal":{"name":"Vegetable crops of Russia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86877761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Relevance. The article describes zones with one or another predominant type of melioration depending on the territorial location of the reclaimed lands, a brief classification of channels is given according to design features, cross-sectional shape, throughput capacity and technical and operational characteristics. Channels are the main elements of reclamation systems. Ensuring high-quality operation of channels with the required bandwidth guarantees the efficient operation of the entire reclamation system. Characteristic canal deformations that occur during operation are given, as well as factors affecting the throughput of canals, such as the appearance of sediment, silting and grass vegetation, the growth of shrubs and small trees. The article presents sewer cleaning machines used on canals of reclamation systems during cleaning and restoration work, describes their design features for cleaning canals of various types and cross sections. Canal cleaners are described, which, according to the mode of operation, are both intermittent and continuous machines, which most effectively and efficiently clean the bottom and slopes of channels of various reclamation systems. The article also provides an explanation of the increase in the efficiency of canal cleaning and the subsequent high-quality work of the reclamation system in the case of using various complexes of sewer cleaning machines, including a variety of machines with different working bodies, sizes and quantities. The choice of the number of machines is directly related to technical and economic indicators: the use of a large number of machines may not be economically feasible, and the use of a minimum number of machines will not provide the re-quired cleaning. Thus, it is important to choose the optimal number of machines of various sizes that form a separate complex.

Relevance. The study is aimed at evaluating the biological effectiveness of insecticides to reduce the number of tobacco thrips and gourd aphids in a film greenhouse on gourds. These pests cause significant damage to plants and can carry a viral infection. In greenhouse conditions, tobacco thrips can produce up to 7-8 generations, and melon aphid – up to 16 generations per season. The recommended pest control products have a limited protective duration in protected ground conditions, and in most cases promote the development of resistance in insects.Results. The article presents the results on the use of the insectoacaricide MatrinBio, BP against melon aphids and tobacco thrips, and the biological effectiveness in reducing the number of pests is determined. A single treatment with a bioinsecticide kills up to 90% of tobacco thrips insects. Efficiency against melon aphids is 27% lower. It is noted that the period of the protective action of MatrinBio, BP lasts up to seven days, then decreases. On the fourteenth day, the biological effectiveness against pests is; for thrips – 72%, and for aphids – 40%. For comparison, bioinsecticide Fitoverm, EC, was chosen as a standard, which showed worse results in reducing the number of tobacco thrips (less by 20...25%), but had the best protective effect against melon aphids - by 19...21%. Re-treatment with drugs seven days after the first one significantly reduced the number of pests. To prevent the emergence of resistance in pests in protected ground conditions, it is recommended to include MatrinBio, BP in the integrated protection system and alternate with insectoacaricides from other classes or use in various combinations.

Relevance. Cucumber green mottled mosaic virus (CGMMV) is a highly specialized virus (group Tobamovirus). It is a significant threat to cucurbits. On a high infectious background, cucumber yield losses, both in open and protected ground, can be close to 100%. The spread of the virus occurs in many ways. The most dangerous is the infected seed material. One of the effective methods of preventing CGMMV is the creation of genetically resistant hybrids to viral diseases. An experiment was conducted to determine the effectiveness of the use of the marker F295 for the selection of resistant samples.Results. When comparing the results of determining resistance against an artificial background and the results of PCR analysis for the same samples, we calculated the efficiency of the genetic marker F295, which was 65%. Since the level of effectiveness is average, for a more objective assessment, it is necessary to create another – the main marker, which will determine the direct presence of resistance to CGMMV. The use of the F295 marker is relevant in combination with other methods for deter[1]mining resistance, which will speed up and increase the efficiency of the breeding process.
