Potatoes with pigmented tubers contain anthocyanins and other phenolic compounds that demonstrate antioxidant activity and have a beneficial effect on human health. The nutritional value and other consumer qualities of available potato varieties must be combined with resistance to various infections, primarily late blight, which leads to significant yield losses and considerable costs for chemical protection. The purpose of this work was to assess late blight resistance of 46 promising potato hybrids with different pigmentation patterns, both in the field and by laboratory methods, including molecular screening. The objectives of this study included obtaining promising hybrids of colored potatoes characterized by a set of economically importatnt traits, laboratory and field assessment of the resistance of leaves and tubers to the late blight pathogen Phytophthora infestans, as well as molecular screening of late blight resistance gene markers (Rpi genes). The production, cultivation and evaluation of the hybrid material was carried out using standard methods. Field and laboratory resistance of leaves and tubers was assessed on a 9-point scale. Molecular screening was carried out using PCR analysis. The scientific novelty of the work lies in the fact that for the first time a comprehensive assessment of the resistance to late blight of hybrid material of colored potatoes obtained on the territory of Russian Federation was carried out. According to the results obtained, the studied samples demonstrated a high level of resistance of tubers and leaves in field conditions and laboratory tests. However, the results of the study did not reveal a relationship between laboratory or field resistance and the presence of Rpi gene markers, which may be due to the influence of many independent factors that determine horizontal resistance.","PeriodicalId":125083,"journal":{"name":"Agrarian Bulletin of the","volume":"73 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140378264","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 scientific novelty lies in the assessment of the sectoral development of agro-industrial territorial systems, through the study of the dynamics of the main indicators of agricultural activity using trend analysis in a fairly short period of modern economic uncertainty, which is a significant step forward in this area of scientific research. To identify the dynamics and forecast the development of the main sectors of agricultural production, methods were used to graphically identify linear dependence and construct linear trends using homogeneous statistical indicators. The main results of the study are the developed measures for the stable sectoral development of rural areas of the Russian Federation in modern conditions and overcoming the existing regional differentiation. The implementation of measures involves the introduction of innovative solutions that provide an adaptive response to market trends and changes in the influence of external factors in the regional management of sectoral development of rural areas. Thus, the study provides a basis for understanding the components of sectoral development of rural areas and allows us to identify ways to constructively solve complex and multifaceted problems associated with the stabilization of agricultural production.

The scientific novelty lies in the development of a structural model for making a managerial decision, taking into account the use of AI systems, the main components of this process are identified. The research methods were the analysis of publications in the WoS scientific citation network on the topics “agriculture” and “artificial intelligence”, as well as the abstract-logical method in the analysis of the main stages of making a managerial decision. The results of the study were the determination of the composition and content of the stages of the procedural decision invariant, taking into account the use of artificial intelligence systems.

The purpose is to assess the impact of factors determining the magnitude of the environmental impact of agricultural production on land resources. Methodology and methods. In the course of the study, nonparametric statistical methods were used to identify dependencies in the data set. When constructing predictive models, ROC-analysis was used to find the values of the cut-off point. Results. The study made it possible to localize three groups of regions of the Russian Federation that differ quite significantly in terms of the environmental impact of agricultural production on land resources and are characterized by a high level of dispersion within the groups. The analysis of the interrelations between the parameters characterizing the level of environmental impact made it possible to identify factors that have a decisive influence on the indicators of reproduction of land fertility. In regions with a high negative environmental impact, only the yield value is crucial, the growth of which leads to an increase in the uncompensated removal of soil fertility elements, and, accordingly, to the progression of land degradation. In regions with an average level of negative environmental impact, its magnitude also depends on the amount of organic fertilizers applied, which forms a less high level of uncompensated removal of soil fertility elements and, accordingly, environmental damage in the regions included in this group. In the group with a positive environmental impact, it is the level of application of organic fertilizers that has a decisive influence on the reproduction of land fertility. The regression analysis showed that when approximating the values of the positive environmental impact on land resources, the amount of organic fertilizers can be the most reasonable variable. ROC-analysis regarding the application of organic fertilizers for grain crops as a potential predictive parameter of positive environmental impact showed that its threshold value at the cut-off point is 2.56 tons per 1 ha.
