Relevance. Currently, downy mildew of cucumber (peronosporosis) is the most harmful disease on this crop in the open ground, has an epiphytotic character and causes significant damage to the crop of greens. Material and methods. The research was carried out on selection and collection material of the laboratory of selection and seed production of pumpkin crops in the open and protected ground of the Moscow region. At least 300 collection and selection samples of cucumber were sown in the open and protected ground (Moscow region) every year, for phytopathological evaluation. Their defeat by downy mildew was taken into account on a 5-point scale. Results. Among the varieties of FSBSI FSVC selection, were less affected by this disease: Edinstvo, Electron 2, Vodoley, Vodopad, F1 Debut, F1 Krepish, F1 Brunette, F1 Frant, F1 Krasotka and F1 VNIISSOK 1. The most resistant to peronosporosis were Japanese varieties – Sadao rishu, Jibai, Higan Fushinari, Tropical slicer and others. Some Polish hybrids – Aladyn (SKW 190), Heron (SKW 290) and Parys (SKW 390), also had increased resistance to downy mildew. It should be noted that the varieties Jerelo and Geim from Ukraine; Dutch hybrids – F1 Sequenza, F1 Bejo 1612, F1 Pontia, 85/2292, F1 Donia mix; from the United States – F1 Calypso. In the selection for resistance to downy mildew you can to use varieties created in the Far East, the Crimean experimental breeding station. As a result of the annual assessment of parent forms on a natural infectious background, samples with increased resistance to downy mildew were selected.

Приведены результаты испытания нового перспективного партенокарпического гибрида огурца корнишонного типа F1 Энеж 21, созданного селекционерами агрохолдинга «Поиск», в условиях открытого грунта в Северо-Западном, Центральном и Волго-Вятском регионах Российской Федерации: Костромская, Ярославская, Московская, Рязанская, Тульская область и Чувашская Республика. Высокие потенциальные возможности и адаптационные свойства гибрида F1 Энеж 21 наиболее значимо проявляются в Московской области (63,8 т/га), Чувашской Республике (39,4 т/га) и Рязанской области (31,2 т/га).The article presents the results of testing a new promising parthenocarpic pickling cucumber hybrid F1 Enezh 21, selected by the breedrs of the Agricultural holding «Poisk» in conditions of open ground in the North-West, Central and Volga-Vyatka regions of the Russian Federation: Kostroma, Yaroslavl, Moscow, Ryazan, Tula regions and the Chuvash Republic. The high potential and adaptation characteristic of the F1 Enezh 21 hybrid are most significantly presented in condition of the Moscow region (63.8 t / ha), the Chuvash Republic (39.4 t / ha) and the Ryazan region (31.2 t / ha).

Development institutions are an important modern instrument of government regulation of the economy in all developed countries. The system of development institutions of the Russian Federation includes the federal and regional development institutions. Key federal development institutions include such well-known state corporations as the investment fund of the Russian Federation; the State Corporation "Bank for Development and Foreign Economic Activity (Vnesheconombank)"; the state corporation "Russian Corporation of Nanotechnologies," etc. According to experts of the Ministry of Economic Development of the Russian Federation, about 200 regional development institutions operate on the territory of the constituent entities of the Russian Federation. The objectives of this extensive system of development institutions so far have been to overcome the so-called "market failures," which cannot be optimally realized by the market mechanisms, and to promote the sustained economic growth of a country or an individual region. In November 2020, the Government of the Russian Federation announced the reform of the system of development institutions in the country. The article analyzes the goals and main directions of the announced reform. On the example of the system of development institutions of the Far East, an attempt was made to assess its possible consequences.

On the basis of quantitative and qualitative expert sociological surveys, the article presents a model of anti-corruption education in Russia. This model is formed by seven main elements: basis, principles, subjects, objects, methods and means, content of materials (semantic orientation), indicators of the effectiveness of anti-corruption education. Comparing the obtained sociological data characterizing these elements with the corresponding elements of the anti-corruption mechanism enshrined in the current regulatory legal acts of the Russian Federation, the authors identified a number of inconsistencies. They concern, first of all, the principles, subjects of implementation of anti-corruption education, as well as indicators for assessing its effectiveness. For example, experts suggest using non-statutory principles of financial support and standardization of materials presented in the framework of such education when conducting anti-corruption education. At the same time, for the optimization of management decisions in the field of anti-corruption education, scientific and practical interest and contradictions identified within the obtained sociological data are of interest. Such contradictions are most clearly traced in relation to the subjects and objects of anti-corruption education.

В работе идет речь о реализации методики вероятностного цунамирайонирования побережья, известной под названием PTHA (Probabilistic Tsunami Hazard Assessment), для создания обзорных карт цунамиопасности дальневосточного побережья России. Обсуждаются методологические основы такого подхода, проблемы построения сейсмотектонических моделей основных цунамигенных зон, численные методики получения расчетных каталогов высот волн на побережье. Приведены примеры обзорных карт для различных повторяемостей, построенных с применением методики PTHA и представленных с помощью созданного веб-приложения WTMap. Упоминаются также некоторые проблемы применения методики PTHA, связанные как с недостаточностью данных наблюдений, так и со сложностью выполнения большого объема сценарного численного моделирования. The article describes the results of the implementation of the PTHA (Probabilistic Tsunami Hazard Assessment) methodology for creating the overview maps of tsunami hazard for the Far East coast of the Russian Federation. Such maps show the characteristics of the catastrophic impact of tsunami waves on the coast and the probability of their exceeding in a given period of time. The methodological basis of the PTHA approach to the assessment of tsunami hazard, the problems of constructing seismotectonic models of the main tsunamigenic zones, mathematical models and algorithms for calculating probability estimates of tsunami danger are discussed. The version of the PTHA methodology outlined in the article is implemented as a “WTmap” Web-application that has an access to the entire observational information related to coastal tsunami zoning and software packages used. The application allows to obtain the estimates of the expected tsunami heights and their recurrence estimates and to map them on specific parts of the Far Eastern coast of the Russian Federation. The obtained estimates can be quickly recalculated when replacing the observational catalogs with more complete and reliable ones, with the addition of new, previously absent events or the revision of their parameters, as well as the results of new scenario calculations. Examples of overview maps for various recurrence intervals, constructed using the PTHA methodology and presented using the “WTMap” application, are given. Some problems of using the PTHA methodology related to the lack of available observational data and to the complexity of performing a large amount of scenario simulations are also discussed.

The article is devoted to the analysis of the problems of protecting the right of indigenous peoples of the Far East to traditional fishing. To improve the legal regulation in this area, according to the author of the article, will allow the development of special procedures for resolving disputes with the participation of indigenous minorities, as well as amending the legislation of the Russian Federation regulating the rules of traditional fishing for indigenous minorities.
