The excretion and inculcation of stamped varieties of tomato and hybrids into production are of particular value in conditions of dry subtropics. In this regard, during 2013-2015 in the Surkhandarya Scientific Experimental Station of the Research Institute of Vegetable and Melon Crops and Potatoes, a collection of tomato strains was studied for biological and economic precocity, maturity, etc. For the duration of the «young growthflowering» period, the best were No.86, Yamal, GemState, and Sever. Blooming on the first brush, they come in 8-13 days before the standard variety. The Argo, Chelnyok, Ion-N, Alpatyeva 905а, L-923-92 samples with a duration of 38-40 days have a short period of «flowering-ripening». Maturation of the first fruit (fetus) occurs 1-3 days earlier than the standard. By weight of the fetus, the samples studied can be divided into two groups: medium fruit (61-93 g) – L-923-92, Argo; small fruit (28-58 g) – GemState, Ion-N, Sever, Nevsky, etc., only 10 samples. The total yield varies from 16.4 to 55.5 t/ha, depending on the variety. Samples No.86 and Chelnok are 7.7 and 12.3% higher than the standard for the general harvest. The lowest overall yield is GemState, Ion-N, Sever, Nevsky, Yamal, Argo, L-923-2, with a yield of 16.4-34.1 t/ha, which is 33.2- 69.0% of the standard. The only sample No.86 for the early harvest is 32% higher than the standard. As a result of the study and a comprehensive assessment of tomato stamping varieties, the biologically early ripened ones are Sever, Nevsky, Ion-N, Otradny, GemState, the sprouting-maturing period of which is 95-99 days; economically early ripened – No.86; amity of ripening of samples – Yamal, Sever, Ion-N, Nevsky, Stamped Alpatyeva 905a, GemState, with maturity ripeness from 69 to 90%. They are a valuable source material for selection of stamped, early-ripening, amity of ripening varieties of tomato for dry subtropics conditions of Uzbekistan.

Селекцией моркови столовой в России занимаются ФГБНУ ФНЦО, Агрохолдинг «Поиск», ООО «Селекционная станция имени Н.Н. Тимофеева» и другие. Цель работы – подбор исходного материала и создание новых линий-опылителей моркови столовой с одновременной доработкой имеющихся в генетической коллекции ВНИИО-филиала ФГБНУ ФНЦО. Исследования проводили в 2011-2019 годах в условиях Московской области на экспериментальной базе и в селекционном центре ВНИИО-филиала ФГБНУ ФНЦО. Материалом для работы служили сорта и гибриды отечественной и иностранной селекции, селекционный материал, полученный от межлинейных и межсортовых скрещиваний. Селекционную работу проводили методом многократного инбридинга (до I3-4). По мере отработанности селекционного материала на устойчивость к альтернариозу и фузариозу, морфологическую выровненность, переходили на сибсовые скрещивания. Селекционный процесс по созданию новых линий-опылителей осуществлялся в питомнике исходного материала и селекционном питомнике. В результате селекционной работы было получено 14 новых линий-опылителей моркови столовой и доработаны 4 линии, имеющиеся в генетической коллекции ВНИИО-филиала ФГБНУ ФНЦО. Большая часть линий-опылителей (5 шт.) принадлежит сортотипу Курода, четыре - Берликум/Нантская, по три – Берликум, Флакке, две – Шантенэ, одна – Нантская. Общая урожайность линий варьирует от 70,9 до 110,0 т/га. Наибольшую урожайность формировали линии 93-2, 98, 56-2. Значительные пределы содержания β-каротина (11,1 – 16,8 мг%) связаны с происхождением линий. Отмечено, что инбредные линии, полученные из исходного материала иностранной селекции содержат меньше β-каротина. Шесть линий относятся к позднеспелым, десять – к среднеспелым, две – к раннеспелым. В результате оценки инбредных линий по устойчивости к грибным болезням установлено, что 16 линий принадлежат к слабовосприимчивым на инфекционных и естественном фонах, две линии – средневосприимчивые: 805 – на инфекционном фоне Alternaria, REW – по двум инфекционным фонам. На естественном фоне все линии относятся к слабовосприимчивым. The selection of carrots in Russia is carried out by FSBSI FSVC, Agroholding «Poisk», LLC «Breeding station named after N.N. Timofeeva» and others. The purpose of the work is to select the initial material and create new pollinating lines for carrots with the simultaneous refinement of those in the genetic collection of the ARRIVG- a branch of the FSBSI FSVC. The studies were carried out in 2011-2019 in the conditions of the Moscow region on the experimental base and in the selection center of the ARRIVG - a branch of the FSBSI FSVC. The material for the work was varieties and hybrids of domestic and foreign selection, breeding material obtained from interline and intervarietal crosses. The breeding work was carried out by the method of multiple inbreeding (up to I3-4). As the breeding material worked out for resistance to Alternariaand Fusarium, morphological uniformity, they switched to sib crosses. The breeding process for the creation of new pollinator lines was carried out in the nursery of the source material and the breeding nursery. As a result of breeding work, 14 new lines-pollinators of carrots were obtained and 4 lines, which are available in the genetic collection of the ARRIVG- a branch of the FSBSI FSVC, were modified. Most of the pollinator lines (5 pcs.) belong to the Kuroda variety type, four - Berlikum/Nantes, three each - Berlikum, Flakke, two - Chantenay, one - Nantes. The total yield of the lines varies from 70.9 to 110.0 t/ha. The highest yield was formed by lines 93-2, 98, 56-2. Significant limits of β-carotene content (11.1 - 16.8 mg%) are associated with the origin of the lines. It was noted that inbred lines obtained from the source material of foreign selection contain less β-carotene. Six lines are late maturing, ten are mid-maturing, two are early maturing. As a result of the assessment of inbred lines for resistance to fungal diseases, it was found that 16 lines belong to weakly susceptible on infectious and natural backgrounds, two lines are moderately susceptible: 805 - according to the infectious background Alternaria, REW - according to two infectious backgrounds. On a natural background, all lines are weakly receptive.

This essay analyzes the theological changes which are reflected in successive revisions of Southern Africa's Anglican liturgy from 1900 to 1989. The following liturgies are examined: A Book of Common Prayer—South Africa (1954); Proposals for the Revision of the Rites of Baptism and Confirmation (1967); the Church Unity Commission's ecumenical liturgies in the 1970s; Birth and Growth in Christ (1984); and An Anglican Prayer Book 1989. The article also includes valuable source material which influenced the revised liturgies, including two official reports on the theology of baptism and confirmation. The author finds that theological uncertainty surrounding the underpinning of current rites brings into question whether full church membership is actually granted during baptism.

ABSTRACT Correlations and path analysis between characteristics can aid the selection of important attributes in breeding programs. Thus, the objective of this work was to perform genotypic, phenotypic correlations and path analysis under commercial yield of garlic bulbs, depending on morphological and agronomic variables. The experiment was carried out in 2017 at the Universidade Federal dos Vales do Jequitinhonha e Mucuri and Universidade Federal de Lavras, using ten garlic genotypes, eight trials and two commercial cultivars, Caçador and Jonas. We evaluated: plant height; number of leaves, total bulb number; total bulb mass, total bulb yield, marketable bulb yield and number of cloves per bulb. The genotypic and phenotypic correlations were positive and significant between marketable yield of bulbs with bulb mass, total yield and number of cloves per bulb, indicating that selection based on these characteristics will help increase the yield of garlic. However, only the number of cloves per bulb had a direct effect and a relevant indirect effect on the marketable yield of garlic.

The article emphasizes the importance of peas as a source of vegetative protein, and indicates on insufficient areas under peas both in Russia and in the Altai. One of the reasons of reducing its acreage is the high costs on peas planting and protecting from pests, diseases and weeds. Climate changing contributes to rapid development of such harmful diseases as ascohitoz, bacteriosis, fusarium, rust, significant number of weevil, pea aphid and moth mullet. Considering the main directions in pea breeding, it should be emphasized that the Altai Area, with its vast territory and diverse natural and climatic conditions, requires highly productive, well-adapted varieties of different use which are capable to effectively use agro-climatic resources of different zones. All this requires the active study of the source material, the selection of new, economically valuable forms and their introduction into the breeding process. It has been noted that the production requires more advanced varieties, the development of which is impossible without the presence of diverse source material. The purpose of the study was to identify the best productive plants in the pea collection of 2012-2017. The material has been represented by 113 variety samples of domestic and foreign selection. The varieties with best productivity were ‘Mnogoplodny 163’, ‘Rheinperle’, ‘Flagman 12’, ‘806’9, ‘Varyag’, ‘Altaisky Usaty’, ‘Pioner’, ‘LittleMarwel’, ‘Mnogoplodny 27’, ‘Zeleny Tsukat’, ‘Ryadovoy’, ‘576/80’. The best forage productivity was produced by ‘Novosibirets’, ‘Varyag’, ‘Pino’, ‘Zeleny Tsukat’, ‘Mnogoplodny 105’. The most fast-ripening varieties were ‘Rheinperle’ and ‘Pyrama’. The samples ‘Novosibirets’, ‘Varyag’, ‘Pino’ and ‘8067’ were characterized with high plant height. The samples ‘Pyrama’, ‘Flagman 12’, ‘Novosibirets’, ‘Sihirobana-Kinusaja’, the line ‘312’ produced large-sized kernels. The great lodge resistance has been shown by ‘Altaisky Usaty’, ‘Svetozar’, ‘Kamerton’, ‘Flagman 12’.

Abstract. Rice can form not only white, but also red, brown and black grains. In black rice, pericarp grains contain anthocyanins, which have antioxidant activity and are beneficial to human health. The purpose of the work is to study the inheritance of the black color of the pericarp and other qualitative traits in the intersubspecific hybrid of rice Kuboyar × Gagat, the selection of the best recombinant forms combining early ripeness, a compact erect panicle and black grain, the creation of the source material for practical selection. Methods The studies were carried out on hybrids of the first and second generation from crossing a white-grain variety of rice Kuboyar with black-grained Gagat in 2018–2019 in the Separate Division “Proletarskoye” of the Rostov Region. Results. A genetic analysis of the inheritance of the duration of the growing season, qualitative signs of coloring of flower scales and rice grains, and spinousness was carried out. In the second generation, 54 photosensitive non-flowering plants and 128 normal ones broke out, which indicates the interaction of four dominant genes in the genotype. The splitting according to the color of the pericarp was carried out according to the trihybrid scheme according to the type of com-plementarity in the ratio of 27 black: 21 brown: 16 white. The black color of the pericarp was formed when three dominant genes Kala1, 3, and 4 were present in the genotype, brown was determined by the Kala4 gene, and white by the remaining combinations of genes. According to the color of flowering scales, the cleavage occurred according to the digrid pattern: 9 black: 3 yellow with black apiculus: 4 straw yellow. Although the parental varieties were boneless, 39 spinous forms appeared in F2 with three complementary dominant genes An-a, An-b, An-c and inhibitor I, the remaining 89 plants were boneless. The best recombinant forms were selected, combining the optimal values of plants and panicles and black grain, the source material for practical selection was created.

Today modular construction is gaining popularity in the arrangement of production facilities. The purpose of the research is the theoretical substantiation of the choice of the optimal thickness of thermal insulation for external protections of modular buildings taking into account the evaluation criteria based on the method of hierarchy analysis. The article reflects the possibility of using modular buildings for residential and public needs. Given the peculiarities of the use of thermal insulation materials, such structures are erected in a short period of time due to the use of ready-made modules. It is also proposed to use multicriteria analysis to compare different thicknesses of thermal insulation of a modular building. The obtained results are presented in the form of petal diagrams and diagrams of global priorities, which made it possible to make an in-depth assessment of several thicknesses of thermal insulation. When conducting theoretical research, it should be noted that the importance of each of the criteria was taken into account for the selection of thermal insulation. An expert assessment was performed to determine the thickness of thermal insulation, which can be used for lightweight prefabricated structures of modular buildings. As a result of research, it was found that the most suitable thermal insulation material is polyurethane.
