Цель исследований: изучение новых гибридных комбинаций лука репчатого по основным хозяйственно ценным признакам. Исследование проводили в 2019–2020 годах в отделе селекции и семеноводства ВНИИО – филиале ФГБНУ «Федеральный научный центр овощеводства» с постановкой опытов в открытом и хранилище с регулируемыми температурно-влажностными характеристиками (Раменский район Московской области). В опыте участвовало семь новых гибридных комбинаций лука репчатого, в качестве стандарта использовали гибрид F1 Премито (Monsanto) и отечественный сорт Форвард (совместной селекции агрофирмы «Поиск» и ВНИИО – филиала ФГБНУ ФНЦО). Посев проводили в III декаде апреля, из расчета 0,8 млн шт/га. В течение вегетационного периода вели фенологические учеты, биометрические измерения и проводили морфологическое описание согласно общепринятым методическим указаниям. Мероприятия по уходу за растениями проводили в соответствии с рекомендациями для зоны возделывания. Изучение морфологических признаков и биометрических показателей проводили по малой выборке (10 растений) каждого образца. Число зачатков определяли на поперечном разрезе луковицы. Интенсивность воскового налета на образцах оценивали визуально. Лук закладывали в хранилище с оборудованными холодильными установками, автоматически регулирующими температуру, влажность и циркуляцию воздуха. Для лучшей сохранности этой культуры поддерживали температуру в хранилище около 1–2 °C и относительную влажность воздуха – в пределах 75–80%. Результаты оценки новых образцов лука репчатого в условиях Московской области позволили выделить гибридную комбинацию 652/15 F1 (Шет × Ливингстон I3) с высокой урожайностью (59,5 т/га) и сохранностью в зимний период (84,7%), которая соответствует параметрам разработанной модели для условий региона и обладает конкурентными преимуществами. New varieties and hybrids of onion should have economically valuable characteristics necessary for the market, therefore, the priority is to create heterotic hybrids of this crop, showing increased viability, high and stable yield and alignment, general resistance to pathogens and good keeping quality. The purpose of the research: to study new hybrid combinations of onions according to the main economically valuable characteristics. The study was carried out in 2019–2020 in the Department of breeding and seed production of ARRIVG – branch of FSBSI FSVC with the staging of experiments in open ground and storage with adjustable temperature and humidity characteristics (Ramensky district of the Moscow region). Seven new hybrid combinations of onions participated in the experiment, the hybrid F1 Premito (Monsanto) and the domestic variety Forward (joint selection of the Poisk Agro Firm and ARRIVG – branch of FSBSI FSVC) were used as a standard. Sowing was carried out in the third decade of April, at the rate of 0.8 million pcs/ha. During the growing season, phenological records, biometric measurements were carried out and morphological description was carried out according to generally accepted methodological guidelines. Plant care measures were carried out in accordance with the recommendations for the cultivation zone. The study of morphological features and biometric indicators was carried out on a small sample (10 plants) of each sample. The number of rudiments was determined on a cross section of the bulb. The intensity of wax plaque on the samples was assessed visually. Onions were placed in storage with equipped refrigeration units that automatically regulate temperature, humidity and air circulation. For the best preservation of this culture, the temperature in the storage was maintained at about 1–2 °C and the relative humidity in the range of 75–80%. The results of the evaluation of new onion samples in the conditions of the Moscow region allowed us to identify a hybrid combination 652/15 F1 (Shet × Livingston I3) with high yield (59.5 t/ha) and preservation in winter (84.7%), which corresponds to the parameters of the developed model for the conditions of the region and has competitive advantages.

Organic geochemical and palaeobotanical reconstruction of a late-Holocene archaeological settlement in coastal eastern India

Integration of palaeobotanical (spores, pollen, phytoliths and non-pollen palynomorphs) and organic geochemical proxies, such as stable isotopes of organic carbon (δ13C) and n-alkanes, for studying the evolution and palaeoenvironmental conditions of an archaeological site are rare in India. The evolution of a protohistoric-historic site at Erenda, situated in the eastern coastal region of India, has been studied by using multiple palaeobotanical and organic geochemical proxies assisted with AMS radiocarbon dates. The excavated site lies above Late Pleistocene–Early Holocene Sijua Formation. The absence of anthropogenic evidence in the Sijua Formation likely indicates inhabitable conditions in nearshore/estuarine marshy conditions. The earliest human settlements at the excavation site begin during the first millennium BCE after the initiation of habitable conditions along the coast. The presence of fungal spores and the dominance of C4 phytolith morphotypes indicate prevailing warm and humid climatic conditions and proximity to a freshwater body. The δ13C signature and n-alkane composition indicate the use of C4 grass for the construction of the mud and clay-built huts. The settlers most likely used to consume wild or domestic variety of rice, as evidenced by the presence of bilobate scooped morphotypes. The site was partly abandoned, covered with C3 and C4 vegetation and used as a dumping ground after 663 ± 92 BCE. This implies that people continued to live in the area but possibly moved to a nearby site while using the excavated site as refuse.

BLACK WHEAT BRAN AS A PROMISING SOURCE OF FOOD FIBRES WITH AN EXPANDED SPECTRUM OF FUNCTIONALITIES

Modern requirements of nutritiology determine the enrichment of a person’s daily diet with food fibres. Dietary supplements and cereal-based ingredients are widely used to achieve this goal. Wheat as a food crop traditionally occupies a leading position in food production. Currently, new varieties of wheat with colored grains are being given increasing attention as a source of high-activity phytochemical compounds, which can initiate a positive synergistic physiological effect in the complex. The black-grain wheat of the domestic variety "Chornobrova" belongs to the functional species among the new valuable colored varieties of wheat. It contains an increased amount of biologically active components concentrated in the husk and germ of the grain. At grain processing plants by-products are formed in the production of flour and cereals, among which the hard shells of grain release in the form of bran, that have a rich source of dietary fibres. The paper describes the breaking bran and grinding bran of black-grained wheat "Chornobrova". They contain up to 78.0% of polysaccharides, among which hemicelluloses and cellulose predominate. Both types of black wheat bran are protein-rich (13.0-15.3%), and the crude fat content does not exceed 2.1%. The non-hydrolyzed residue, represented primarily by lignin, reaches 3.8%. Bran is rich in phenolic compounds – powerful antioxidants with the mass fraction 310.0 mg/100 g. Both types of bran have a water retention and sorption capacity towards toxicants (phenol, Pb2+), cholic acid, methylene blue. As a result of acid treatment of bran, dietary fibre concentrates were obtained, in which non-starch polysaccharides predominate. They are characterized by modified physicochemical properties, namely improved water holding capacity, sorption activity against Pb2+, not inferior to bran in terms of the ability to bind cholic acids and methylene blue. "Chornobrova" wheat bran and dietary fibre concentrates are highly active enterosorbents with antioxidant activity, which can be considered as dietary supplements and food ingredients that should be included in recipes in the development of new functional foods.

Supercritical CO2 extraction of oils from red grape varieties: Yields and extraction parameters

In this work, the extraction by supercritical carbon dioxide of grapeseed oil from five red grape varieties was investigated. Apart from an indigenous variety Prokupac, as the domestic, and Merlot and Cabernet Sauvignon, as international grape varieties the most represented in the Republic of Serbia, Pinot Noir and Gamay were studied as well. Extraction conditions were: temperature of 50?C, 250 bar pressure, and 0.3 kg/h flow rate of CO2. It was shown that the extraction kinetics of international grape varieties, mutually similar differ significantly from the domestic one. The obtained oil yields were in the range of 8.3% w/w (Gamay) to 10.4% w/w (Pinot Noir) for the international varieties and 5.0% w/w for the domestic variety. The mathematical model ?Sovova? was applied to define transport parameters regulating the oil mass transfer inside the seed particles and determine the agreement between experimental and model curves. The interpretation of results took into account the differences of grade seed morphologies (outer surfaces and inner layers) which was investigated by SEM analysis.

Efficiency of pelleting of sugar beet seeds in centrifugal pelleting machine

Seed pelleting is an efficient way to improve the sowing quality of seeds. Diverse positive effect of pelleting is mostly noticeable for beet seeds. Increased size and spherical shape of seeds with shell allows to use precision seeding technology, as well as fertilizers and protective agents being part of the shell, increase their sowing potential and finally increase yields. To obtain pelleted seeds, it is required to use a specialized line with a seed pelleting machine being the main equipment. An improved design of centrifugal batch-operated seed pelleting machine has been developed and manufactured in Belarusian State Agricultural Academy. To activate the process of rolling the shell in the mixing chamber of the pelleting machine, it was proposed to use separately installed blades. Based on theoretical and experimental studies, the main structural and technological parameters of the pelleting machine has been determined to ensure the highest quality of pelleted seeds. Seeds of sugar beet of the domestic variety “Polybel” obtained in a favorable climate were selected for experimental studies. Finished mixture based on bentonite clay was selected as a filler of the seed coat. After the coat formation, the insect-fungicidal dressing agent Prestige was applied to the seeds. The seeds of sugar beet of the domestic variety “Polybel” obtained on experimental pelleting machine showed high results in germination and yield. They are comparable to imported sugar beet hybrids. Pelleting of seeds of domestic varieties of sugar beet on the territory of the Republic of Belarus can become a good alternative to imported pelleted seeds, especially considering their cost, which significantly exceeds the cost of untreated seeds.

Interdisciplinary teams in apple breeding and co-authors of varieties

The article presents the results of 64 years apple breeding work at the Russian Research Institute of Fruit Crop Breeding (RRIFCB) and shows the high role of the interdisciplinary team. It is noted that at the RRIFCB, leading institute for fruit crop breeding in Russia, over the past period 54 apple varieties of different ripening periods have been created and included in the State Register of breeding achievements admitted for use. Among them 19 are first in Russia and in the world triploid varieties derived from intervalent crossings of type 2 × 4; 24 immune to scab (with the Vf gene), including the first immune to scab domestic variety Imrus (immune Russian) and 5 columnar scab immune varieties. Triploid apple varieties are characterized by more regular fruiting by years, high fruit marketability and partial self-fertility. Scab immune apple varieties when introduced into orchards contribute to a more favourable environmental situation in the orchards and their surroundings and reduce the cost of additional chemical treatments. Columnar varieties make it possible to create super-intensive orchards with an early abundant yield and to simplify and reduce labor-intensive costs for the formation and care of trees. The creation of all these types of varieties was possible thanks to a large interdisciplinary team, which in addition to the main breeder includes specialists of many other specialties: variety specialists, phytopathologists, biochemists, geneticists (about 20 researchers). Among the 54 new apple varieties created at the RRIFCB, only one variety Pamyat Voinu was created by one breeder and two varieties (Orlik and Orlovskoye Polosatoye) were created by the main author and one co-author. The rest of the varieties were created by three and more co-authors. Specialists of different specialties (interdisciplinary teams) are needed for successful breeding work. The success of breeding work also largely depends on the volume of the hybrid fund. With a large amount of material in the plant nursery and breeding orchard, a more rigorous selection for the desired characteristics is possible.

Efficacy of tertiary egg membranes as calcium zones for embryonic development in poultry breeds

Background Growth and production of any animal husbandry including poultry depends on early development, growth, feeding, environmental and other factors. Early and later embryonic development forms a significant parameter in poultry production, during which human or technological intervention is practically impossible. Results Embryonic development is governed by very many internal factors among which, egg calcium utilization is of prime importance. An experiment was set up to investigate the egg calcium utilization of different poultry breeds at its embryonic development. Four breeds of locally available chicken ( Gallus gallus domesticus ), Broiler, Common domestic variety ( Nadan ), Vanaraja and Gramapriya breeds were selected and embryonic egg utilization was assessed by comparing calcium content of egg shell before and after hatching and found out that Vanaraja breed utilizes maximum (0.20gm) and significantly (P < 0.01) higher quantity egg shell calcium for embryonic development followed by Local breed (0.16gm) and least used variety was Broiler breed (0.09gm). Conclusions The study highlighted the criticality of the composition of the specific mineral in the calcium zones for embryonic utilization underlining the importance of its only source through food.
