The paper presents results of research into breeding of the new soybean cultivar Gorinskaya by the methods of hybridization and individual selection. Soybean varieties SibNIIK-315 (female parent) and Fiskebi V (male parent) were used as a starting material. The studies were carried out in the forest-steppe zone of the Western Siberia (Novosibirsk region). Soybean Gorinskaya belongs to the Manchu subspecies. The plants have a light brown (reddish) pubescence of the stem, leaves, beans. The growth pattern and the type of apex is intermediate, the number of branches is 1–3, the angle of branching is 20–30 degrees, the bush is compressed. The height to the first branch is 6–10 cm, the attachment height of the lower pod is 10–13 cm. The beans are distributed evenly throughout the plant. The length of the stem is 55–75 cm, the number of internodes on the stem is 12–15. The inflorescence is a small-flowered raceme of 3-5 flowers. The corolla is purple in color. The pods are slightly curved with a pointed tip; when ripe, they acquire a brown color. The seeds are elongated-oval, greenish-yellow in color, without pigmentation. The seed hilum is brown. The cultivar is the grain variety for use. The yield in the competitive variety testing reached 29.4 c / ha. The mass of seeds per plant is 10–12 g, the mass of 1000 seeds is 150–160 g. The number of seeds per pod is 2-3; the average number of pods per 1 productive node is 2-3. The protein content in seeds is 35-38, fat – 17-19%. Duration of the vegetative period is 100-105 days. The cultivar is medium resistant to diseases, cold, drought, and soil salinity. In 2018, the Gorinskaya soybean variety was included in the State Register of Breeding Achievements Approved for Use in the Russian Federation for the East Siberian region.

Abstract The aim of the study was to study the use of hydrogen peroxide and ascorbic acid of different concentrations as an activator for the incubation of artemia cysts. The work was carried out on cysts of artemia taken from several lakes of the Novosibirsk region (Western Siberia). During incubation, a standard method was used: the salinity of the water was 3%, the water temperature was 28□C, continuous aeration was carried out, constant illumination was 2000 lux. An activator was added to the water at different concentrations: ascorbic acid - 0.05, 0.1, 0.5, 1.0 g/l; hydrogen peroxide - 0.4; 0.6; 0.8; 1. The maximum hatching was observed at a concentration of 0.6 g/l of hydrogen peroxide, 82% for cysts from Lake Sakhalin and 68% - from Lake Barbashi. When using ascorbic acid, the maximum hatching of cysts was observed at a concentration of 0.1 g/l: Sakhalin - 81.4, Pokrovka - 75.3 and Barbashi - 66.7%. When using other concentrations of activators, the percentage of cysts hatching decreased. The obtained results indicate the need to select the activating substance and its concentration of activation of cysts for each lake individually.

Objective of research: to perform the analysis of long-term (15 annum) dynamics of Bithyniidae snails infected by trematode parthenites from the Chany Lake, the biggest lake in the south of Western Siberia. Materials and methods: The Bithyniidae snails examined in the lake-river systems Chany Lake in 1994-2013 (in the middle reaches and in the estuary of the Kargat River) and in the Zolotye Rossypi Bay and the Malye Chany Lake. The Bithyniidae snails were collected from May to September (twice in any ten days) by hand from 4–6 plots of 0.25 m2 at a depth of 0.1–0.7 m. In total, 8,316 Bithynia troscheli (Paasch, 1842) and 766 В. tentaculata (L., 1758) were examined. Identification of parthenitae trematode was based on observation when mature cercariae were capable of leaving the shell of the host snail on their own. Results and discussion: In Bithyniidae snails, we found parthenites from trematodes from 12 families Cyathocotylidae Mühling, 1898 Poche, 1925; Prosthоgonimidae Luhe, 1909; Pleurogenetidae Looss, 1898; Lecithodendriidae Odhner, 1911; Microphallidae (Ward, 1901) Travassos, 1920; Plagiorchiidae Lühe, 1901 Echinostomatidae (Looss 1899) Dietz, 1909 Odhner 1910); Psilostomidae (Looss 1900) Odhner 1913; Notocotylidae Luhe, 1909; Monorchiidae Odhner, 1911; Cyclocoelidae Kossack, 1911 и Opisthorchidae (Lass, 1899) Braun, 1901. The prevalence of bithyniid snails infected by trematode parthenites varied from 1,6% to 24,1% in different years The double infection by trematode parthenites was found in 0,96% bithyniid snails from estuary of the Kargat River; 4,45% in the Malye Chany Lake, and 26,6%, in the Zolotye Rossypi Bay. The cercariae of Opisthorchidae family in four annum of the fifteen detected. The prevalence of bithyniid snails infected by trematode parthenites from Opisthorchis felineus (Rivolta, 1884) and Metorchis bilis (Braun, 1890) was observed in Chany Lake systems for the first time. Both species (O. felineus and M. bilis) of trematodes have danger to human health and causes very dangerous disease, opisthorchiasis and metorchiasis.

The relevance of the research topic is determined by the need to assess structural changes in the territorial and sectoral structure, as well as factors affecting the competitiveness of the regional economy. The article presents the results of calculations of structural changes in the economy of the Novosibirsk region for the period from 2000 to 2016 using the method of "shift-share analysis". The method allows to assess the degree of influence of three groups of factors (national, regional and internal competitiveness of the regional industries) on changes in the regional economy. The article presents the results of calculations of the growth rates employed in certain sectors of the Novosibirsk region by types of economic activity for the period from 2000 to 2016, as well as indicators of the MIX-effect (composition) and DIF-effect (competition). Based on the assessment of structural changes, the types of economic activities that demonstrate the highest indicators of industry competitiveness are determined.

In our research firstly we provide to generalized conceptual basis for the characteristics of organic beekeeping in Russia, second determine the impact of organic beekeeping on the productivity and the third quality of beekeeping products, to assess the possibility. To assess the problems associated with some of the main parameters, we conducted literature review and analysis of beekeeping products obtained in an apiary that implements the principles of organic beekeeping in the south of Western Siberia (Vengerovo village, Novosibirsk region). Article investigates theoretical and practical aspects of the orientation of apiaries to the production of organic products in the context for growing level of competition.

Aim. To study the gene-specific composition of Borrelia spp. in ixodid ticks inhabiting the foci of ixodid tick-borne borreliosis (ITBB) in the south of Western Siberia.Materials and Methods. The gene-specific composition of Borrelia spp. in ixodid ticks was determined by inoculation on a BSK-H nutrient medium, real-time polymerase chain reaction, and sequencing (1148 specimens of ixodid ticks collected from vegetation and 2183 specimens withdrawn from humans).Results. Infection of ticks with borrelia ranged from 22.4% in the Altai Republic to 56.9% in the Novosibirsk Region. There were no significant differences in the levels of Borrelia infection between two major ixodides, I. persulcatus and I. pavlovskiy (average infection levels 40.0% and 38.8%, respectively). At least five gene species of pathogenic Borrelia (B. garinii, B. afzelii, B. bavariensis, B. miyamotoi, and B. spielmanii) have been identified. The GenBank database contains 45 nucleotide sequences of the intergenic spacer rrf (5S)-rrl (23S). Prevalence of gene species B. garinii and B. afzelii in different ticks (I. persulcatus and I. pavlovskiy) did not differ significantly, yet B. garinii was found to be more frequent than B. afzelii. The frequency of infection of I. persulcatus ticks with B. miyamotoi was significantly (3.5-fold) as compared to those of B. garinii and B. afzelii. In D. reticulatus ticks, the DNA of B. spielmanii and B. miyamotoi was detected.Conclusion. It is necessary to continue studies to assess the role of the meadow ticks D. reticulatus in the circulation of different Borrelia spp. in various natural foci within the Russian Federation.
