The rapid spread of this disease in the territory of Russia requires new effective diagnostic tools for the timely detection of infection. To solve this problem, antisera specific to Dickeya spp. were obtained. Polyclonal antibodies isolated from antisera have shown high affinity for the main species of Dickeya spp. ( D. solani, D. dianthicola, D. chrysanthemi, D. dadantii, D. paradisiaca ). Enzyme linked immunosorbent assay (ELISA) and lateral flow immunoassay (LFIA) test systems have been developed based on specific and high affinity antibodies that were obtained. For ELISA, the detection limit was 0.8 105 cells/mL for D. solani and 2 104 cells/mL for D. dianthicola . For LFIA, suitable for use in non-laboratory conditions, the detection limit of D. solani was 2 105 cells/mL and the analysis time was 15 minutes. When testing potato seed material, LFIA test system confirmed positive results of ELISA determination in 75 % of samples, and negative - in 100 % of samples.","PeriodicalId":53086,"journal":{"name":"RUDN Journal of Agronomy and Animal Industries","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44187769","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 allows to provide comprehensive selection on different agronomic traits and to achieve permanent assortment improvement. The main aim of the research was to select seabuckthorn varieties distinguished by characteristics that meet the requests of industrial sector with focus on various technological approaches. Seabuckthorn varieties of hybrid origin from crossbreeding of 1993-2005 were studied. The experiments were carried out in forest-steppe zone of Altai Krai in 2016-2020. According to the results of comprehensive evaluation, groups of the most promising varieties were proposed as a source of various agronomic traits. The potential of breeding activity was shown as well as possibility of seabuckthorn assortment improving was proved. In particular, within sweet-fruited varieties such samples as 57-01-1, 146-02-1 and 226-00-1 with sugar-acid index of 6.4, 5.4 and 5.3, respectively, have been selected as well as fruit of 198-99-3a and 62-01-2 varieties weighed about 1.0 g, that is almost 0.3 g higher compared to Chuiskaya variety (control) and Altaiskaya (the sweetest one). Two varieties - 149-00-3 and 664-00-2 - were included to the group with very low tear-off force of fruits - 95 and 110 g, respectively, which was significantly lower compared to the control (Chuiskaya) and the standard variety (Anastasia). That means high suitability of these varieties for harvesting by hand picking. The hybrid 185-99-5 had an average fruit weight of 1.67 g which was two times higher than fruit weight of the control variety. Highly promising red colored variety (258-03-1) had high oil content in fruits. That positions it as an extremely promising variety for seabuckthorn oil concentrate processing. Most of estimated varieties were included in various reference groups demonstrating by that the combination of agronomic traits.","PeriodicalId":53086,"journal":{"name":"RUDN Journal of Agronomy and Animal Industries","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44909953","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 genus Destructor is one of the most problematic genera of plant-parasitic nematodes. The numerous species reported for this genus have been cited from various sources. Due to the morphological similarity of many species and the lack of separation characteristics, the identification of D. destructor is difficult. Molecular taxonomy and phylogeny were used to confirm the identification. In the current study, PCR-RFLP illustrative models for the amplification of the ITS-rRNA gene were provided with two enzymes that could recognize D. destructor in potato tubers. Analysis of the rDNA sequences spanning both ITS1-ITS2 regions was carried out on the collected populations. The digestion of the PCR product of the ITS1-5.8S-ITS2 region with the enzyme TaqI produced three fragments; 100, 190, 550, and with Tru1I, two fragments were produced; 300 and 480 bp. The obtained DNA sequences were compared with those DNA sequences deposited in GenBank of populations isolated in other countries. The results showed no distinction between populations isolated from different host plant species, including populations found in the Russian Federation.

In this regard, chemical plant protection requires special attention in terms of safety management. The method of strip chemical treatment of crops reduces the effects of chemically hazardous substances on plants, emphasizing the importance and relevance of the research direction. Based on the analysis of production costs for chemical treatment, the shortcomings of serial machines for chemical plant treatment were identified. A technology and technical solution for strip spraying with redistribution of operating solutions to the exposure objects, considering plant growth stage, were proposed. It allowed to accurately adding the active substance to the object, which caused decrease in application rate per hectare, reduction of plant stress, and saving in costs for chemical treatment. Simultaneously, it contributed to the solution of environmental problems by reducing chemical load on soil. This method reduces the risk of emergencies when using chemically hazardous substances in agriculture.","PeriodicalId":53086,"journal":{"name":"RUDN Journal of Agronomy and Animal Industries","volume":"11 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41296603","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}

Productivity is one of the most important traits that breeding is aimed at. It is a very complex trait, the formation of which is influenced by many different factors, both internal (the genotype of the plant) and external. The genes responsible for the gibberellin sensitivity played a large role in multiplying yields of cereal crops. Another such gene is the Gid1, which encodes a receptor for gibberellins. This article compares the DNA sequences of the Gid1 gene obtained from six Dasypyrum villosum samples. Using a sequence of wheat and rye taken from the GenBank database (NCBI), we selected primers for regions of different genomes (A, B, and D subgenomes of wheat and the R genome of rye), and carried out a polymerase chain reaction on D. villosum accessions of diverse geographical origin. The resulting PCR product was sequenced by an NGS method. Based on the assembled sequences, DNA markers have been created that make it possible to differentiate these genes of the V genome and homologous genes of wheat origin. Using monosomic addition, substitution, and translocation wheat lines, the localization of the Gid1 gene of D. villosum was established on the long arm of the first V chromosome. A phenotypic assessment of common wheat lines carrying substituted, translocated, or added D. villosum chromosomes in their karyotype was performed. Tendency of disappearance of the first chromosome of D. villosum in the lines with added chromosomes was revealed.","PeriodicalId":53086,"journal":{"name":"RUDN Journal of Agronomy and Animal Industries","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41803497","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 research revealed that there was no significant difference in agrophysical indicators between the soil cultivation variants. Data on weed infestation of winter rape fields showed that the number of weeds and their weight increased significantly after subsoil tillage. At the budding stage, the number of weeds increased 2.1-fold compared to the control (real tillage), and the weight of weeds increased 1.88-fold.
