Background. Lodging has an extremely negative impact on barley yield: grain quality and planting properties are deteriorated, disease incidence increases, and mechanized harvesting becomes difficult, so it is important to find new sources of lodging resistance in barley and use them in crosses and breeding programs to develop non-lodging barley cultivars.Materials and methods. Experimental work was carried out in 2018 and 2019 at Federal Agricultural Science Center of the North-East (FASC North-East), Kirov. Yield structure components and lodging resistance levels were assessed for 29 accessions from the spring barley collection. The study was based on the International COMECON List of Descriptors for the Genus Hordeum L. (subgen. Hordeum) and Methodological Guidelines for the Study and Preservation of the World Collection of Barley and Oats.Results and conclusions. Lodging resistance was observed to have a strong correlation with yield (r = 0.72) and plant height (r = –0.60), and a medium correlation with tillering (r = 0.40) and number of nodal roots at maturation (r = 0.44). No relationship was found between lodging resistance and morphological features of the second lowest internode, which means that selection of non-lodging forms by these criteria will not be effective. Lodging-resistant accessions demonstrated higher yield, tillering, productivity, 1000 grain weight, and a longer and denser ear compared to nonresistant accessions. Accessions combining high yield with lodging resistance and a set of traits promising for breeding were identified: ‘Belgorodsky 100’, ‘Naran’ (k-30892), ‘Kazminsky’ (k-30926), ‘Shchedry’ (k-31046) (Russia); ‘Syabra’ (k-30917), ‘Raider’ (Belarus); ‘Odesssky 115’ (k-29010, Ukraine), ‘Mie’ (k-30379, Estonia), ‘Rodos’ (k-30256, Poland).

The paper explores 70 samples of spring barley from the collection of WIR under conditions of rather rigid natural infectious helminthosporioses (striped, reticulated and dark brown spotting) in FARC of the North-East in 2018-2019. The spotting was investigated 4-5 times during plants ontogenesis every 10-12 days since the phase 29 on the Cadox scale. The methodology suggested by O.S. Afanasenko (2005) was used to assess the diseases. The nature of vegetative-microbial interactions was evaluated by SCDP (square under the curve of disease progress) and IS (stability index) indicators. During immunological experiment, the authors observed 11 samples resistant to dark brown spotting with lesion rate 10.0-13.0%, SCDP parameters equal 167-223, DUT was 0.18-0.25; 18 samples resistant to reticular spotting (6.0-10.0%, PCRB - 53-103, DUT - 0.18-0.35), and 29 samples characterized by immunity and high resistance to stripe spotting (0-5.0%, SCDP - 10-75). IS - 0.01-0.09). Only 4 samples (Makbo, Kalkul, Buyan and Forward) are characterized by group non-specific resistance to reticulate and dark brown spotting and striate immunity. The longest occurrence period (2-7 days) of dark brown spotting was observed in 8 samples, and reticulum spotting (2-13 days) - in 16 samples. The paper finds out that NCL 95098 (Argentina) had the relatively long occurrence period in terms of dark brown spotting, and varieties from Afghanistan (k-5983) and China (k-2929) to reticulate spotting. Badiory, Makbo, Rodos, and Buyan varieties have equal dynamics of both spotting and slow rusting of diseases in ontogenesis. There is a weak (r = -0.33 - reticulate) and medium (r = -0.58 - dark brown) negative correlation between the latent period and the defeat. The regression equations (y = -0,6071x+6,8571; R2 = 0,917 - dark brown; y = -0,3941x+11,35; R2 = 0,733 - reticulated) show that from infection to the first disease symptoms, their daily increase in trend is 0,61 and 0,39%. Kalkul, NCL 95098, Badioryi and Buyan varieties are seen as effective promising for selection programs to produce high yield adaptive varieties under the conditions of the region. Apart from stability, they are distinguished by the number of productive stems, long, well-grained ears and high productivity.

Background. The efficiency of breeding depends largely on the breeding method and the choice of the source material. Hybridization and mutagenesis, combined with selection, are the basic techniques in the development of promising breeding materials and adaptable cultivars of spring barley.Object and methods. The research was implemented in 2002–2019. The material for the research were 948 breeding lines (Federal Agricultural Science Center of the North-East, Kirov) developed through hybridization with cv. ‘Bios 1’, and 190 mutant samples (Vyatka State Agricultural Academy, Kirov) obtained as a result of treating barley seeds with sodium carbonate and irradiation with laser and far-red light in various combinations. The study was conducted in accordance with approved standard techniques.Results and conclusions. Various collection accessions and breeding lines were involved in crosses with cv. ‘Bios 1’. The lines were studied according to the full-scale scheme of the breeding process. As a result, only one breeding line, 52-15, having ‘Bios 1’ in its pedigree, was approved for testing in the competitive variety trial in 2019. These results attested to a low combination capacity of cv. ‘Bios 1’ and to the inefficiency of its further use in hybridization as a parent form. In Vyatka State Agricultural Academy, 190 mutant forms of barley were produced using ‘Bios 1’ as the initial form. According to the results of laboratory experiments and competitive variety trials, 5 mutant forms of barley were identified as promising. Spring barley samples, combining high yield with a set of traits valuable for breeding, were selected for further breeding work: breeding line 52-15, and mutant forms M 4-16-3, M 9-5-3 and M 11- 13 Kha. The new barley accession M 8-3-013, maturing 8 days earlier than the original cultivar, having a long (8.9 cm), wellgrained (24.3 grains) and productive (1.31 g) ear, is submitted for the State Variety Trials.

The results of the study of 12 varieties and promising lines of glumaceous oat in the competitive variety testing of the FASC of the North-East (Kirov region) in the period from 2018 to 2020 are presented. The purpose of the research is to assess the productivity, ecological plasticity and stability of the genotypes of glumaceous oat for feed and universal use in the conditions of the Volga-Vyatka region. The dependences of grain yield and dry matter harvesting on the state of agro-climatic resources (HTC), temperature and precipitation are established. The contrasting weather conditions during the years of research allowed to conduct the most complete assessment of the studied genotypes. The most favorable conditions for the formation of a high yield of green mass of oat were formed in 2020 (Ij=3.76), grain - in 2019 (Ij=1.35). The average degree of positive dependence of green mass yield on the height of oat plants was revealed (r=0.51). The variety of the high-intensity type of the universal direction Medved, promising lines of the mowing direction (178h13 and 245h14) are distinguished.

Based on the statistical assessment of long-term field studies, in competitive variety tests, barley cultivars were identified adaptive to the conditions of the region, promising for transfer to the State variety test. As a result of the studies, a promising breeding material was created. The efficiency of using various methods of creating a new initial material, in particular, the cell culture method, is shown. A statistically significant correlation was established between the value of the hydrothermal coefficient (GTK) in the period “leaf tube formation - heading” and the yield capacity of a cultivar (r = 0.520). High variability (V = 24.4%) in the duration of the inter-stage period “leaf tube formation - heading” was revealed in the cultivars of competitive variety testing. Cultivars 94-13 and 38-15 are distinguished by a high yield potential (up to 6.4… 6.9 t/ha) and the duration of inter-stage periods, at which the main stages of organogenesis occur at the most favorable combination of heat and moisture for the potential development of plant features and properties. Cultivars 207-15, 38-15, and regenerant 550-08, characterized by high annual average yield capacity (5.9…5.7 tons/ha) and adaptability, are promising for transfer to the Russian Federation State variety test.

The article is devoted to the analysis of the structure of sown areas and characteristics of barley varieties zoned in the Kirov region for 2020. In 2019 in the Kirov region the varieties cultivated in production for more than 20 years had the largest specific weight – 50.1 % of the acreage occupied with barley. Those cultivated for more than 10 years had 36.1 %; from 5 to 10 years – 13.8 %. Certified sowings varied from year to year in percentage to the occupied area. There is a gradual decrease in unsorted sowings of barley from 3.0 thousand hectares in 2017 up to 1.18 thousand hectares in 2019. The areas sown with barley varieties bred in Federal Agricultural Research Center of the North East named N. V. Rudnitsky (FARC North-East) in the structure of sown areas in 2019 were from 21.5 % in the southern zone up to 57.8 % in the northern zone of the Kirov region. For the whole of the region the greatest distribution was recorded among Belarussian cultivars Zazersky 85 (39.3 % of the areas sown with barley), and cultivars bred in FARC North-East: Ecolog (10.8 %), Rodnik Prikamiya (7.1 %) and Novichok (7.0 %). In northern districts of the region the ratio changed: Ecolog – 27.2 %, Rodnik Prikamiya – 18.9 %, Novichok – 9.0 %, Zazersky 85 – 7.7 %. High productivity (4.22-4.79 t/ha in average), resistance to lodging and diseases characterize the zoned cultivars. The main disadvantage of barley assortment offered for zoning is the lack of stable yield and differences in duration of the growing season among the varieties. All cultivars belong to the group of mid-season, except for the mid-late cultivar Zazersky 85. The region is short of the sources of high-quality raw materials for forage production; only 30.7 % of all assortment of barley in the region are presented by cultivars with high grain quality (Ecolog, Belgorodsky 100, Rodnik Prikamiya and Pamyati Rodinoy). Currently, the trend for developing high-yield early, resistant to lodging and diseases barley varieties of high grain quality is to become the key factor in breeding work.

The aim of research was to evaluate hybrid black currant families on productivity, large-fruitiness, flavor, resistance to currant gall mite and American mildew and to reveal the best ones in conditions of Kirov region. The studies were held in the experimental orchard of Federal Agricultural Research Center (FARC) of the North-East (Kirov) in 2010-2017. The object of the research was the hybrid of black currant breeding of FARC of the North-East on a plantation established in 2013. The scheme of planting was 3×1 m. 26 hybrid families (453 seedlings) obtained as a result of hybridization in 2010 were evaluated. Observations and recordings were held according to the general methods. For creating hybrid material of black currant the varieties Sapphire, Shagane, Arcadia, Mulatka and forms – as sources of economically valuable features obtained in conditions of Kirov region were used. According to the results of the research, the combinations of hybridization with the maximum yield of hybrid seedlings with valuable features which show an interest for the further breeding were revealed: 41-3-07×Sapphire – early maturity and good productivity (75.6-91.1 %); 10-1-07×Arcadia – large-fruitiness (50.0-66.7 %) and nice flavor (61.5 %); 57-5-07×44-8-96 – with resistance to currant gall mind (100.0 %) and mildew (42.9 %); 69-5-07×Shagane – good productivity (50.0-92.8 %); 102-1-07×Alexandrina, 25-4-07×Mulatka, 99-3-07×34-4-96 – with resistance to currant gall mind (100.0 %). For the further research 12 selected forms of black currant with economically valuable features have been identified, replicated and planted at the site of primary studying. The Sapphire variety became the best parent form in evaluating breeding material. In crossing combinations with its involvement the maximal amount of selected seedlings with economically valuable features (8 from 12 forms) were revealed. In crossing combinations, where the Shagane variety was used as a male parental form, a high yield of productive seedlings was noted.

A fungal strain was selected from the microbial repository of the North-East Institute of Science and Technology, Jorhat, India, which could produce a high yield of l-amino acid oxidase. 18SrRNA, ITS1, 5.8SrRNA ITS2, and partial 28 S rRNA sequencing and phenotypic characteristics indicate that it belong to the species Aspergillus fumigatus (designated as P13). Maximum production of enzyme (59.55 × 10−3 U/mg dry cell mass) was obtained in a medium containing 10 g/L glucose, 4 g/L yeast extract, and 4 g/L ammonium sulfate, with 20 mmol/L of l-threonine as the inducer. The optimum temperature for enzyme production was 30 °C at pH 7.0, with a shaking speed of 200 r/min. At 96 h, the enzyme activity was maximum. The A. fumigatus P13 l-amino acid oxidase accepts a broad substrate range, and the maximum enzyme activity (20.41 × 10−3 U/mg dry cell mass) was obtained with 50 mmol/L of dl-tyrosine. In the literature, no reports have been found regarding the production of l-amino acid oxidase by A. fumigatus. The enzyme showed enantiomerically pure amino acid formation, which has tremendous demand in industrial applications.
