Seven breeding lines F9, created by two-step hybridization of the purple-grain durum wheat with naked and awnless emmer, and five breeding samples of seminaked emmer wheat were studied. In the field experiments, plants were selected for selection valuable traits. Phenological observations, structural analysis, and evaluation of the quantitative traits of the plants of emmer wheat breeding forms with purple grain coloration were carried out from 2020 to 2022. Two-way analysis of variance showed significant factors - the breeding lines and the years of study. In the course of the study, it was found that for further breeding work, emmer wheat lines carrying a combination of economically important traits are of value. Short-stalked purple-grain form 27-1 is resistant to lodging, the yield of the grain - 80 %, the weight of 1000 grains – 34–37 g. Line 27–12 has grains with purple color, high grain-unit value of about 800 g/l and good grain productivity for emmer wheat reaching 400 g/m2. Purple emmer line 31–16 has a good bushiness (3–4 pieces), short stalk (71–74 cm), high lodging resistance (4–5 points) and grain threshing capacity (80 %). From 2021 to 2022, the same studies were conducted with emmer wheat from the collection of the N.I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR). The selection line of emmer wheat 41/14 was distinguished by the high indicator of threshed grains (85 %). The main disadvantages of the established forms of emmer wheat with purple-colored grains still remain relatively low grain yield, insufficiently strong ear shank, not complete grinding of the grain from the flowering glumes and husks. However, further breeding work can improve these traits, as well as increase the grain yield, the weight of 1000 grains and a more complete release of the grain from the chaff during threshing.","PeriodicalId":438227,"journal":{"name":"Siberian Herald of Agricultural Science","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124904679","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}

A total of 10 varieties were studied: Rodnik Prikamya, Novichok, Dina, Zazersky 85, Triumph, Tallon (hybridization and selection); Forward, Bionic, Vitrum (cell selection); In memory of Dudin (mutagenesis). The studies were carried out in 2021 under the climatic conditions of the Kirov region. Seeds of the plants of each variety were sown in vegetation containers filled with soddy-podzolic soil. Cadmium provocative background (6.4 ± 0.5 mg/kg) was created by adding cadmium acetate to the soil. The average yield of barley varieties in the control (soil background without cadmium) was 279 g/m2; against a provocative background – 216 g/m2. Under the conditions of cadmium stress, the yield of hybrids decreased compared to the control by 12.2 %, regenerants – by 29.6 %, mutant – by 42.4 %. Among the studied varieties, the Bionic variety, which has a regenerated origin, showed a consistently high yield both on the control (334 g/m2) and cadmium background (263 g/m2). Productive bushiness of hybrid barley varieties against the control background varied from 2.8 to 4.1; in regenerants – from 3.4 to 4.8; mutant varieties – 4.3 pieces. Under the conditions of cadmium stress, productive bushiness decreased by an average of 2.7 – in hybrids; for 3.4 – for regenerants, for 2.6 pieces – a mutant. Bionic, regardless of the soil background, compared with other varieties, had the highest productive bushiness. Significant differences in the content of polyphenols in the grain of the studied varieties on the control and provocation soil background for cadmium were not revealed. Under the conditions of cadmium stress, a decrease in the content of flavonoids in grain was noted, as well as the accumulation of cadmium (0.29–0.92 mg/kg). Varieties of hybrid origin showed the ability to accumulate cadmium in grain to a greater extent.","PeriodicalId":438227,"journal":{"name":"Siberian Herald of Agricultural Science","volume":"83 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121822053","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}

Barley net blotch is dominant in the pathologic complex of barley diseases worldwide. The pathophysiological processes of infection development depend on the type of resistance of the variety. Net blotch on resistant varieties is noted as small dark rounded spots. Infection often occurs as a result of mechanical damage to the leaf plate. The symptoms of net blotch disease on a susceptible variety have a characteristic reticulate pattern with pronounced necrosis and extensive chlorosis. One of the main ways to protect crops from the disease is the cultivation of resistant varieties. The study was conducted during the  growing seasons of 2020–2022 on artificial infectious background in the sprouting phase phase of the vegetation experiment and in the adult plant on the natural infectious background in field conditions. 10 varieties of winter barley of domestic and foreign selection were selected. Immunological assessment in the sprouting phase revealed two varieties resistant to leaf net blotch, score: Vivat (1.7) and Kvant (1.6); the varieties Artel (3.8), Fox-1 (2.3) of domestic selection and Carioca (2.7) of foreign selection showed moderate resistance. Field moderate resistance was detected in four winter barley varieties, %: Vivat (18.3), Kvant (26.6), Marusya (19.9), Fox-1 (24.9). Immunological assessment of barley varieties recommended for sowing in the south of Russia is one of the main components in the strategy of increasing the efficiency of plant protection measures and improving the ecological component of crops.","PeriodicalId":438227,"journal":{"name":"Siberian Herald of Agricultural Science","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123710668","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}

It is noted that these animal species are of great importance in a number of southern countries, they are used as farm animals (milk, meat, wool), as draft, riding and sports animals. At present, much attention is paid to the study of camels in order to identify their genetic characteristics that can be used in breeding work. One of the research methods is multilocus analysis using labeled oligonucleotide probes. The latter selectively hybridize in separate regions of genomic DNA, leading to the appearance of specific genetic profiles characteristic of each individual. Labeling the probe with digoxigenin makes it possible to detect the results of hybridization on the filter. After the reaction of molecular hybridization of the probe with genomic DNA of camels, from 3 to 15 DNA fragments were detected, while the pattern of hybridization was very different in Dromedaries and Bactrians, which indicates a significant genetic difference in the organization of genomes. The coefficient of similarity of individuals in Bactrians was significantly higher than in Dromedaries (0.48 versus 0.39); interspecific similarity coefficient in this parameter was only 0.13. The calculation of the genetic distance between populations gave a rather high value of 0.305, which is significantly higher than the previously obtained data on cattle (from 0.05 to 0.10). Intrapopulation genetic diversity was assessed by the criterion of average heterozygosity. Calculations showed greater genetic diversity in the dromedary population (H = 0.72), which was indirectly confirmed by a lower similarity coefficient in this group of animals.","PeriodicalId":438227,"journal":{"name":"Siberian Herald of Agricultural Science","volume":"341 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134051566","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}

The data on leukemia at the time of the beginning of active recuperation work and the results after several years were presented. The infection rates of the livestock by different age groups and in different parts of the studied farms were analyzed for 2017-2022. The infection rate of cows on the farms tended to decrease slightly from 2017 to 2019 and was in the range of 8-4%. The infection rate of the heifers was 5-12%. Registration of new cases of serology response in the group of the calves in the farm No. 1 decreased from 9.9 to 4.9%, in the farm No. 2 from 14.2 to 7.1%. The positive dynamics of implementation of the recovery plan using enzyme-linked immunosorbent assay (ELISA) for serological diagnosis was shown. After switching from the immunodiffusion in agar gel reaction (AGID) to ELISA and its first use, the number of newly detected animals increased in all age groups in both farms compared to the previous period. In subsequent studies, the percentage of new cases decreased significantly. Physical separation of the groups of animals with different statuses, placing them in different sections and clear control with the immediate exclusion of infected animals from the production process led to a noticeable improvement in the epizootic situation on the farm. Aspects causing delay in sanitation work were noted, in particular, untimely separation of animals into groups after serological diagnosis and establishment of their infection status. Complete replacement of infected cattle in unhealthy herds or wards by groups of serology-negative animals can significantly reduce the recovery period, especially at the final stage.","PeriodicalId":438227,"journal":{"name":"Siberian Herald of Agricultural Science","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129604462","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}

The studies on the effect of different ratios of the grinding mixture of wheat and amaranth grains on the chemical and physico-chemical properties of wheat-amaranth flour as a result of their joint processing are presented. The object of the study was the grain of winter wheat of the variety Nemchinovskaya 85 and the grain of amaranth of the variety Voronezhsky. Processing of the control sample of common wheat and milling wheat-amaranth mixtures of various ratios was carried out in the laboratory grinding mills (LGM-4) with threaded (for break systems) and smooth microroughened rollers (for grinding systems). It has been found that in the control sample of wheat flour, the weighted average content of fat and protein was 1.12% and 11.57%, respectively, with the addition of 5% amaranth to the grinding wheat-amaranth grain mixture, the weighted average fat content in wheat-amaranth flour was 2.47 %, and the protein content - 12.55%, with the addition of 10% amaranth to the grinding wheat-amaranth grain mixture, the weighted average fat content of wheat-amaranth flour was 3.13%, and the protein content - 12.66%, with the addition of 15% amaranth in the milled wheat-amaranth grain mixture, the weighted average fat content in wheat-amaranth flour was 3.88%, and the protein content was 13.34%, with the addition of 20% amaranth to the milled wheat-amaranth grain mixture, the weighted average fat content in wheat-amaranth flour was 4.29%, and the protein content was 13.78%, respectively. It has been found that the addition of amaranth grain to the milled wheat-amaranth mixture up to 20% of amaranth grain significantly increases the yield of wheat-amaranth flour.

It was found that on condition of using 9,0 m wide reapers with Russian models of combine harvesters and 9,2 m with Byelorussian models, for harvesting works it is rational to use Vector 410 with the yield of 1,8-2,4 t/ha and GS 10 PRO with the yield of 2,45-3,00 t/ha. In this case, their technical potential can be fully realized and the maximum productivity in terms of both harvested area and threshed grain can be ensured. The use of more productive combine harvesters for direct harvesters in Siberia is not always justified, because at the current level of grain yields here their technical potential cannot be fully realized.

Infectious diseases of horses are registered in almost all countries in Asia, Europe and America. In Russia, Kazakhstan, Kyrgyzstan, and Mongolia, the most common diseases are strangles of horses, rhinopneumonia, and salmonella abortion, which cause significant economic damage to herd horse breeding. Various monovaccines are developed and produced in foreign countries, most of them have no use in Russia. We have found a simultaneous disease of mares with rhinopneumonia and salmonellosis, as well as young horses with rhinopneumonia, salmonellosis and strangles. In this regard, the development of monovaccines and combined immunobiological preparations is becoming an urgent problem. Immunogenicity of infectious vaccines should be enhanced by immunomodulators, especially in the extreme conditions of herd horse breeding. At a time when antibiotic-resistant strains of microorganisms are a problem, alternative antibacterial agents should be developed: probiotics and bacteriophages. Eight new microbial strains have been isolated, identified, and deposited in all-Russian collections. Sahabaktisubtil probiotic has been developed, which is used to prevent and treat dysbacteriosis, mycotoxicosis, strangles, leptospirosis, decontamination of manure. New effective vaccine preparations and “Yakutskaya Koumissnaya” starter culture have been developed that can be successfully used to increase the productivity of horse breeding in other regions of the Russian Federation and abroad.

It is of great interest to study the experience of using this innovative tool to produce pigs with specified traits. The development of molecular genetic research and the discovery of gene-phenotype relationships has provided the platform needed to modify specific genes to significantly shorten the reproductive cycles and improve the efficiency of pig breeding. The relatively recent CRISP/Cas9 system has already found use in many advanced fields of research, but its application is limited in the challenges of pig breeding, including the production of transgenic pigs. It is due to the fact that there are ethical and regulatory issues associated with genetically-edited products and the potential non-target effects of CRISPR/Cas9 that need to be investigated. Genomic editing technology is actively developing worldwide. Russia is implementing the 2019-2027 genetic technology development program. The main goal of the program is to comprehensively address the problems of accelerated development of genetic technologies, including genetic editing technologies. Obtaining results through genomic editing of farm animal lines with new, improved properties is one of the program’s target indicators.
