Productivity of apple variety Majesti in the foothill zone of Dagestan

The article presents the results of studying the productivity of the parameters of the introduced apple variety Majesti on the clonal rootstock M9 in the agro-ecological conditions of the southeastern foothill sub-province of Dagestan. The purpose of the research is to identify the biological potential of the variety, the adaptive potential for the construction of intensive-type orchards in the industrial horticulture zone. It is especially important to choose the optimal variety-rootstock combinations of apple trees, which should be distinguished by early maturity, annual productivity, high commercial quality of fruits and environmental sustainability. The southeastern foothill sub-province has great prospects for the development of industrial horticulture. Of the unfavorable environmental factors that negatively affect the vital activity of fruit crops, the most often noted are return colds in spring and early frosts in autumn, when fruit plants are still growing. In accordance with the research program of the Federal Agrarian Scientific Center of the Republic of Dagestan, it is envisaged to study the influence of different rootstocks (M9, SK-2, SK-7, MM106) on the productivity of the Majesti variety. Based on the research results, biometric indicators of the growth and productivity of trees in a young garden were determined, depending on the type of planting design. It was noted that at the age of three, the condition of trees on a 5-point scale is good. The height of the trees, depending on the rootstock, reached an average of 2.3 to 2.9 m. On dwarf rootstocks M9, the stem diameter of the Majesti variety was 4.2 cm, of the control variety Renet Simirenko — 3.5. The growth of annual shoots clearly reflects the growth activity of trees with different varieties of rootstock combinations. It has been established that the growth of dwarf rootstocks provides a weakening effect and allows growing lowgrowing trees with a compact crown, a strong stem, that are convenient for earning and harvesting. The largest number of fruit formations was noted in the introduced cultivar Majesti with a 3.0x1.5 planting pattern on a dwarf stock M9 (67 pieces) then in comparison on the control variety Renet Simirenko it was46 pieces. Productivity per tree was 7.1 kg, in the control variety Renet Simirenko — 5.3 kg. Calculated per hectare, productivity of the Majesti variety is 15.7 tons, Renet Simirenko — 11.7 tons.

Introduction. In 2019, thanks to Dani Savelli, Associate Professor of the University of Toulouse Jean Jaures (Toulouse, France) and Ms. Jacqueline Chasselut, the collection of archival materials of a Kalmyk emigrant family in France was received by the Archive of the Kalmyk Scientific Center. The collection contains unique documents testifying to the life of the Kalmyk diaspora abroad. The purpose of the article is to give a general overview of the collection, as well as to examine it as a source on the history of Kalmyk Buddhism. Results.The Zol´vanovs’ collection, now a part of the records of the Archive of the Kalmyk Scientific Center includes 66 items, such as photographs and copies of photographs, official and personal letters, postcards, Buddhist texts, and images of Buddhist deities (prints, photographs, and postcards). Thus, despite the relatively small size of the collection, it is an important source as an example of a Kalmyk family abroad both in terms of history of Russian emigration and of Buddhism of the Russian peoples. The article publishes some rare photographs illustrative of the ties between the Kalmyk emigrants settled in different parts of the world, as well as of their interaction with Tibetan monasteries.

Promising two-row covered cultivars for increasing yield and quality of barley grain in conditions of the southern forest-steppe of Western Siberia

Agroclimatic features of the regions of barley cultivation necessitate the creation and cultivation of cultivars characterized by adaptability to local bioand abiofactors. Such cultivars are able to form a stable high-quality crop regardless of the conditions prevailing during the growing season. The developing of potentially high-yielding cultivars is a priority task of barley breeding in the West Siberian region. Two-row barley is characterized by grain equalization, reduced husk content and increased extractive content, compared to sixrow barley. The aim of the study was to characterize the new promising cultivars of barley (two-row covered group) selected in Omsk Agrarian Scientific Center. The research was conducted in the southern forest-steppe of Western Siberia in 2012-2019. 8 cultivars of coverd two-row barley selected in Omsk Agrarian Scientific Center were studied. There are new promising cultivars among them: Omskiy 100 (included in the Russian State Register in 2019) and Omskiy 101 (sent to the State Registration Service in 2018). The standard cultivar was Omskiy 95 (2007). The biochemical parameters of grain were determined: protein content, crude fat, starch, husk content. Barley selection from 2000 to 2019 focused on the developing of drought-resistant cultivars, which formed increased productivity and quality of grain in dry and arid periods of vegetation in conditions of optimal moistening. New promising cultivars - Omskiy 100 and Omskiy 101 were characterized by the formation of increased indicators of grain quality and productivity in vegetation periods that were contrasting in climatic characteristics. Due to increased yield and grain quality, cv. Omskiy100 had increased protein (+57.91 kg/ha), starch (+0.3 t/ha) and fat (+11.7 kg/ha) harvest compared to the standard. Cv. Omskiy 101 increased protein harvest by 84.9 kg/ha in comparison to the standard.

Assessment of Brassicaceae Seeds Quality by X-ray Analysis

A serious problem of vegetable production is the quality of sown seeds. In this regard, assessment of seed quality before sowing and storage is of great practical interest. The modern level of scientific research requires the use of instrumental automated methods of seed quality evaluation, allowing to obtain more information and in a shorter time. The material for the study was a variety of samples from the collection of Brassica oleracea L., var. capitata, Raphanus sativus L., var. radicula, and Lepidium sativum L. seeds from the Federal Scientific Center of Vegetable Breeding and the Timofeev Selection Station. Digital X-ray images of seeds were obtained using a mobile X-ray diagnostic device PRDU-02. Automatic analysis of digital X-ray images was performed in the software “VideoTesT-Morphology 5.2.” The following latent defects of cabbage seeds of economic importance were revealed and identified: irregular darkening, significant “patterning” with deep separation of embryo parts, “angularity of seeds” leading to the loss of their viability. Automatic analysis of digital X-ray images of seeds confirmed the informativeness of brightness indices of digital X-ray images, as well as shape indices. Their connection with sowing qualities of the studied seeds was established.

Genital endometriosis: controversial issues and alternative approaches to diagnosis and treatment

On the basis of the Department of Operative Gynecology of the Scientific Center for Obstetrics, Gynecology and Perinatology of the Russian Academy of Medical Sciences from 1992 to 2002. examination, treatment and monitoring of 1234 patients with endometriosis was carried out, which served as material for the study of morphofunctional, endocrine, immune, biochemical, genetic aspects of endometriosis. Our clinical and scientific experience allowed us to determine our own positions and a circle of discussion questions corresponding to the main directions of further research on this problem, which are: is endometriosis a disease or not ?; development mechanisms; classification; diagnostic criteria; features of histological characteristics; endometriosis and genetics; endometriosis and the immune system; endometriosis and adenomyosis; retrocervical endometriosis; endometriosis and pelvic pain; endometriosis and adhesions; endometriosis and infertility; traditional and non-traditional approaches to diagnosis and treatment.

A NEW VARIETY AND PROMISING SAMPLES OF NURSERIES BREEDING GALEGA

Биоклиматический потенциал Псковской области позволяет ежегодно получать качественные семена практически всех видов многолетних злаковых и некоторых видов бобовых трав. Первостепенная роль в производстве кормов принадлежит сеянным травам как в полевом (площадь земель составляет 182,8 тыс. га), так и луговом кормопроизводстве (естественные сенокосы (230 тыс. га) и пастбищам (244 тыс. га). Основными направлениями в повышении продуктивности и улучшении качества кормовой базы, на наш взгляд, должны стать новые сорта многолетних трав, возделывание которых ведется с использованием современных агротехнологий. Селекционная работа по выведению новых сортов козлятника восточного ведется в 7 питомниках на полях ФГБНУ ФНЦ ЛК Обособленного подразделения г. Пскова. На каждом этапе селекционного процесса, в каждом питомнике выделены лучшие образцы по ряду хозяйственно ценных и морфологических признаков. На заключительной многолетней стадии, в питомнике конкурсного испытания высеяны сортообразцы, которые выделены из различных питомников с сохранением отличительных признаков, морфологических или хозяйственно-ценных. Селекционерами института создан новый сорт козлятника восточного Талисман (сортообразец №24), превышающий по продуктивности и качеству сорт-стандарт Кривич на 7-10%, в среднем за годы испытаний (5 лет) урожайность зеленой массы составила 38,1 т/га, сухой массы – 9,7 т/га, что выше стандарта на 11%. Семенная продуктивность в среднем за 5 лет была на уровне 4,5 ц/га. Содержание сырого протеина в сухом веществе данного сорта было на уровне от 20 до 22,0%. Выход сырого протеина с урожаем составил 1,9 т/га. The bioclimatic potential of the Pskov region makes it possible to annually obtain high-quality seeds of almost all types of perennial grasses and some types of legumes. The main role in feed production belongs to sown grasses both in the field (the land area is 182.8 thousand hectares) and in meadow forage production (natural hayfields (230 thousand hectares) and pastures (244 thousand hectares). In our opinion, the main directions for increasing productivity and improving the quality of the feed base should be new varieties of perennial grasses that are cultivated using modern agricultural technologies. Breeding work on breeding new varieties of Eastern goat is carried out in 7 nurseries in the fields of the Federal state budgetary scientific center of the LPR, a separate division, Pskov. At each stage of the breeding process, each nursery selects the best samples for a number of economically valuable and morphological characteristics. At the final multiyear stage, in the nursery of competitive tests, varietal samples were sown, which were isolated from various nurseries with the preservation of distinctive features, morphological or economically valuable. Breeders of the Institute have created a new variety of Eastern talisman goat (variety type No. 24), which exceeds the productivity and quality of the standard Krivich by 7-10% on average, over the years of testing (5 years), the yield of green mass was 38.1 t/ha, dry mass – 9.7 t/ha, which is 11% higher than the standard. Seed productivity on average for 5 years was at the level of 4.5 c/ha. The content of crude protein in the dry matter of this class was at the level of 20 to 22.0%. The yield of crude protein from this crop was 1.9 t/ha.
