В 2017–2020 годах проведены экологические испытания существующих сортов и новых селекционных образцов овсяницы красной, созданных на основе исходного материала, полученного из местных популяций, произрастающих в различных экотопах мелового юга Среднерусской возвышенности. Объектом изучения были сорта овсяницы красной газонного типа Россинант (стандарт), Гостёнка, Искринка, Везёлка и 14 селекционных образцов, выделившихся в селекционном питомнике по комплексу морфо-биологических признаков, характерных для сортов газонного направления. Опыты проводили в трёх экологических точках: г. Геленджике (Краснодарский край); пгт Новомихайловский (Туапсинский район Краснодарского края); с. Драгунское (Белгородский район Белгородской области). Изучали продуктивность побегообразования, выраженную в среднем количестве сформированных побегов в год, и урожайность зелёной массы. Установлено, что исходный материал обладает высокой побегообразующей способностью и невысокой надземной продуктивностью, сопоставимыми с сортами, широко используемыми в газонных культурфитоценозах. Анализ корреляции между изучаемыми признаками показал, что в условиях юга Среднерусской возвышенности (экологическая точка «Белгородская область») с высокой вероятностью можно вести селекционную работу и отбор ценных генотипов овсяницы красной для условий Черноморского побережья Западного Кавказа по признаку «Среднегодовой прирост побегов». Показана корреляционная связь этого признака между экологическими точками «г. Геленджик» и «Белгородская область», подтверждённая достоверной корреляцией рангов Спирмена средней силы (rs = 0,446, P > 0,05). Не установлено тесной связи между урожайностью зелёной массы в экологической точке «Белгородская область» и экологических точках Западного Кавказа. В связи с этим для оценки селекционного материала необходимо проводить широкие экологические испытания исходного материала в экологических точках регионов, в которых предполагается использовать перспективные сорта. Сделано заключение о возможности использования исходного селекционного материала мелового юга Среднерусской возвышенности для создания сортов газонного направления для условий Западного Кавказа. The variety trial for red fescue genotypes tool place in 2017–2020. Local populations growing in the south of the Central Russian Upland were used as parental material to obtain the genotypes. The following lawn varieties were tested: “Rossinant” (standard), “Gostenka”, “Iskrinka”, “Vezelka” as well as 14 other genotypes carrying the number of valuable traits. Plants were grown in three different locations: Gelendzhik; the Tuapse region; the Belgorod region. The trial tested the average number of shoots formed in a year as well as green mass productivity. Parental lines actively formed shoots but had low productivity similar to widely cultivated lawn varieties. Red fescue genotypes with high annual shoot yield were widely spread in Gelendzhik and the Belgorod region (rs = 0.446, P > 0.05). The correlation between green mass productivity and the Belgorod region were insignificant same as for the Western Caucasus. It is highly important to test parental lines in the area of respective cultivation. Parental material from the south of the Central Russian Upland can be used to develop lawn genotypes for the Western Caucasus.

The results of breeding work on creation of the new cultivar of red clover are presented. The hybrid population (15-10-D (2n)) was created by the method of crossbreeding and selection in the conditions of artifi cial climate. Selection of winterhardy high-yielding forms of this hybrid population was conducted in the forest-steppe zone of West Siberia. The population 15-10-D (2n) was tested in three cycles of competitive variety trial (crops of 2006, 2008 and 2010) and was submitted to the State variety testing under the name Prima. According to the results of the competitive variety trial during 2007–2013, the new early-ripening diploid cultivar Prima showed high winter hardiness of 97.0-99.0%. The duration of the growing season is 115 days (on the level of standard early-ripening tetraploid cultivar Meteor). The yield of green mass in two cuts is 19.6-58.7 t/ha, the yield of dry matter is 4.2-13.5 t/ha, the yield of seeds is 276-392 kg/ ha. The average yield of green mass in two cuts of the new cultivar is 38.8 t/ha, the average yield of dry matter is 8.7 t/ha, the average yield of seeds is 317 kg/ha, which exceeds standard cultivar Meteor by 52%. The seed content of Prima cultivar is 52%, Meteor – 38%. The crude protein content in dry matter is 16.1%, the fi ber content is 26.0%. Prima cultivar has been included in the State Register of Breeding Achievements of the Russian Federation to be grown in the West Siberian region since 2019. The copyright certifi cate and patent for the breeding achievement were received.

The article examines the scale and methods of the anti-Russian military-political activity of British emissaries in the Western Caucasus in the first half of the 19th century. The scientific novelty lies in the fact that for the first time in the work the intelligence activity of British “traveling” agents in the Western Caucasus is subjected to a special study, as an independent, gaining strength way of fighting in international contradictions for the Caucasus. The relevance of the topic of the proposed article seems to us indisputable due to the incompleteness of international rivalry and the eternal Eastern question. Russian Empire in the late 20s — early 30s XIX century. took possession of all legal rights to the North-West Caucasus and outlets to the Black Sea. With its confident military successes and new territorial accessions, Russia threw a serious challenge to the European powers, and especially England, the dominant power on the European continent at that time. One of the most important tasks of England is to nullify all the achievements of Russia in Turkey and prevent its consolidation in the territory of the Western Caucasus. England, adhering to the favorite method of “raking in the heat with someone else’s hands”, and in Circassia is testing its effectiveness. Since the 30s. XIX century. Numerous British agents flooded the Caucasus, turning the Circassians against Russia. The Black Sea coast of the Caucasus has become a place of uninterrupted supply of weapons to the mountaineers. As a result of the work, the author comes to the conclusion that the sources considered in the work can represent a scientific basis for confirming the involvement of Britain in anti-Russian agitation in the Western Caucasus. The uninterrupted supply of weapons to the highlanders organized by British agents helped to maintain military tension and a fighting spirit in Circassia.

The article presents the results of a four-year collection study of promising varieties of spring-sown vetch, Vicia sativa L., for zoning in the conditions of the south-eastern zone of the Kamchatka Territory according to statistical parameters. The aim of the study was to identify stress-resistant, environmentally plastic, stable and adaptive varieties of vetch seed calculated by the yield of green mass. The experimental field of the Kamchatka Research Institute of Agriculture is located in the area of the Pacific influence with a cold summer without a dry season. Hydrothermal conditions during the periods of green mass formation in 2014-2017 were characterized by excessive moisture content, hydrothermal coefficient = 2.0-4.6. The environmental index ranged from -12.08 to 13.2. The correlation analysis revealed a direct relationship between the total yield and the sum of active temperatures, r = 0.9. An inverse correlation was determined between the environmental conditions index and the hydro-thermal coefficient, r = -0.79. The average annual yield of green mass for 4 years was 18.7 t/ha. The level of the average yield of green mass varied from 10.0 to 26.8 t/ha, the limit values varied within 5.5-34 t/ha. In the course of work, 18 varieties of spring vetch were studied, of which 5 valuable varieties were identified for cultivation in the region: Lyudmila (Yср = 26.8 t/ha), Yubilejnaya 110 (25.5), Uzunovskaya 91 (22.8), Tayozhnaya (21.8) and the zoned variety Lugovskaya 85 (18.0 t/ha), capable of producing stable yields in favorable and extreme conditions.

To analyze processes that may lead to long-term changes in pH, lake sediments from five small lakes in the Western and Central Caucasus were studied according to diatomaceous complexes from sediment cores. A proprietary principle of hydrological parameter unification was used to reconstruct numerical pH values. In isotopic dating experiments, a series of numerical pH values for 2000–130 years were generated for the lakes. These data indicate an absence of noticeable changes in pH in the lakes of the Western Caucasus and alkalization processes in the lakes of the Central Caucasus.
