The assessment of the genetic diversity of cultivated varieties is a very important element of breeding programs. This allows the determination of the level of genetic differentiation of cultivated varieties, their genetic distinctiveness, and is also of great importance in the selection of parental components for crossbreeding. The aim of the present study was to determine the level of genetic diversity of oat varieties currently grown in Central Europe based on two marker systems: ISSR and SCoT. The research conducted showed that both these types of markers were suitable for conducting analyses relating to the assessment of genetic diversity. The calculated coefficients showed that the analyzed cultivars were characterized by a high genetic similarity. However, the UPGMA and PCoA analyses clearly indicated the distinctiveness of the breeding programs conducted in Central European countries. The high genetic similarity of the analyzed forms allow us to conclude that it is necessary to expand the genetic pool of oat varieties. Numerous studies show that landraces may be the donor of genetic variation.

Twenty-five barley (Hordeum vulgare and Hordeum distichum L.) and 25 oat (Avena sativa L.) genotypes with a wide range in genetic diversity were performance-tested on summer-fallowed and stubble land for 3 yr. Correlation coefficients between 3-yr mean yields on summer fallow and stubble were 0.70 and 0.91 for barley and oats, respectively. The genotpye × cropping practice interaction for yield was not significant for either barley or oats. Exclusive use of summer-fallow land in performance testing of barley and oats would not preclude identification of high yielding genotypes for stubble cropping. Barley genotypes that were not high yielding on both cropping practices have not been consistently high yielding across environments in regional cooperative tests.

Background. Fungal diseases are the main cause of the deterioration of grain quality and lower yield of cereals crops. Reduction of acreage, and, as a consequence, violation of crop rotation rules, oversaturation of fields with cereals, spring and summer droughts contribute to the mass emergence and widespreading of new obligate and facultative diseases in all regions of the country. Therefore, the search for a variety of donors and sources of sustainability is a vital task.Materials and methods. Materials engaged in the research were kernels of 41 oat accessions from the VIR collection of plant genetic resources, obtained in 2016–2018 in field crop rotations by the Genetic Diversity Research Department of ARHIBAN (Mikhnevo, Stupino District, Moscow Province). The specific diversity of micromycetes in grain was identified using Litvinov’s “wet chambers” technique and light microscopy.Results. The dominant pathocomplex of micromycetes in oat grain in Moscow Province was found to belong to the genera Alternaria (A. infectoria, A. tennuissima), Cladosporium (Cl. cladosporioides, Cl. herbarum) and Fusarium (F. avenaceum, F. culmorum, F. heterosporum, F. nivale var. nivale, F. oxysporum, F. poae, F. proliferatum, F. solani, F. sporotrichioides var. minus, and F. tricintum).Conclusion. The hulled cultivars ‘Bulanyi’ (VIR-15277, Russia, Moscow Prov.) and ‘Zakat’ (VIR-15384, Ukraine), and the naked cultivar Mestnyi (VIR-15290, UK) demonstrated the least contamination with pathogens: Fusarium fungi in these accessions were represented by one species – F. avenaceum.

Background. Structuring and phenotyping genetic diversity is an important aspect of the work with breeding sources and materials. In the Introduction, the authors pointed out the role of N.I. Vavilovs scientific foresight in defining the topical trend in researching the genetic diversity of a crop, particularly the analysis of its biochemical composition. As the target of their research, the authors chose biochemical characters identifiable in the process of metabolomic analysis conducted by means of gas chromatography with mass spectrometry. Materials and methods. The object was the grain of naked and covered forms of common oat (Avena sativa L.) from the collection held by the Oat, Rye and Barley Genetic Resources Department of VIR. The analysis of oil fatty acid content and metabolomic research were performed using the method of gas-liquid chromatography with mass spectrometry on the chromatograph Agilent 6850 (USA). Results. The obtained metabolomic spectra which reflected the metabolomic status of genotypes of various ecogeographic origin were compared among themselves using statistical (principal component) analysis methods. The results of the comparison are discussed by referring to the most important groups of metabolites significant for forming the traits of resistance to stressors as well as the characters related to food qualities of grain products. Special attention has been paid to biologically active compounds determining the functional value of the products for human nutrition: the sum of phenolics in covered forms is five times higher than that in naked ones and the content of glycine amino acid in covered forms is five times higher than in naked grain, with a similar proportion in the content of organic acids, sugars, etc. Conclusion. Differences between metabolomic profiles of naked and covered forms have been detected and statistically verified. Accessions with the most optimal nutritional composition have been identified for food purposes and for the development of resistance to biotic and abiotic environmental stresses.

Avena sativa L., also known as Oat belongs to the Poaceae family, is one of the most significant crops that is grown for its seeds, fodder as well as for human consumption as oatmeal. In the current study, 236 genotypes of A. sativa were analysed for genetic diversity through agro-morphological and SDS-PAGE analysis. Cluster analysis based on agro-morphological characteristics grouped all the genotypes into nine clusters, whereas genotype numbers 537 and 728 were highly different from others. The seed yield production of cluster 9 genotypes was the highest per plant (38.2 ± 0.20 g), while cluster 2 genotypes produced maximum biomass per plant (122.5 ± 9.55 g) as compared to other clusters. In a principal component analysis where four variables were studied, and the observed total variations were 57.60%. Among the genotypes, a maximum grain yield of 38.2 g (each) was recorded for genotypes 22,350 and 728, followed by genotypes 737 and 22,390 (with 36.4 g and 35.6 g of seed productions, respectively). The SDS-PAGE analysis resulted in 13 bands and all the genotypes were grouped into seventeen clusters. At the extreme periphery of the dendrogram, genotype 537 and 22,332 were considered to be the most diverse genotypes. Our findings have implications for both understanding the diversity and relationships among these diverse genotypes of A. sativa and will provide a basis for obtaining the elite germplasm optimally adapted to local conditions. The selected genotypes based on agronomic performance may be potential breeding material to raise successful future cultivars.

In grain of ten genetically divergent oat cultivars (Merkur, Minor Abed, Flaming-Kurz, Nuptiele, Prode, Pellerva, Emperor, Astor, Osmo, Simo) the variability ?-glucan content were investigated. The different value of content of ?-glucan was found. Among analyzed oat cultivars, the highest ?- glucan contents had Pellerva (6.597%), while the least had Simo (2.971%). The contents of ?-glucans were determined by ICC standard Method No 168. The value of ?-glucans varied and indicated the differences and similarities between analysed cultivars. The degree of cultivar similarity was determined by dendrogram on which was discriminated two clusters of similar cultivars toward to contents of ?-glucan . Within cluster 1, a small group of oats, are five cultivars with small distance (Merkur, Minor Abed, Flamings-Kurz, Nuptiele and Prode). The highest similarity in the range of 88 or the least distance in the range of 12. Within cluster 2 was four oat cultivars (Emperor, Astor, Osmo, Pellerva) in which the least differences was between Emperor and Astor with average distance in range 27. Cluster 1 and cluster 2 differed with an average distance of 63. The cultivar Simo expressed the greatest distance to all analysed oat cultivars grouped in two clusters.
