Oat is one of the leading cereals cultivated in the world and in Russia; it has an important fodder and nutritional value. To preserve the entire crop agrobiodiversity worldwide, there is a network of genebanks that hold more than 200,000 oat accessions. International and national genebanks are located in all the world’s countries, but one of the largest oat collections is located in Russia.The global collection of the genus Avena L. (Oats) at the N.I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR) is one of the largest worldwide and consists of over 13,000 accessions. The collection preserves and maintains live accessions of all cultivated oat species: A. sativa L., A. byzantina K. Koch, A. strigosa Schreb. and A. abyssinica Hochst., landraces, breeding lines, spring and winter forms, covered and naked genotypes, and all geographic diversity of 22 wild Avena spp. from 50 countries. This review provides historical background of the collection of cultivated and wild oat species, and who were the main donors of these holdings. The taxonomic system of the genus is briefly presented, which is used as a tool for efficient work and guaranteed safe preservation of accessions. Most of the cultivars developed in Russia have in their pedigree accessions obtained from the global collection of VIR. The passport database contains detailed information about all accessions of the collection, which makes it possible to improve the work with the oat collection, including safe preservation of accessions and their effective evaluation and use as source material for breeding in the leading breeding centers of Russia.Thus, the global oat collection at VIR has factual and potential value for the sustainable development of environmentally friendly agriculture, efficient processing of agricultural products, and production of safe and high-quality food products, including functional foods.

“…Селекция овса направлена на создание сортов с высокими показателями продуктивности, качества зерна и устои� чивостью к неблагоприятным факторам среды (Polonskiy et al, 2019;Kabashov et al, 2020, Shvachko et al, 2021. Для получения таких сортов в настоящее время используются не только методы традиционнои� селекции, но также достижения генетики и биотехнологии, в том числе маркер-ассоциированная и геномная селекция (Shavrukov, 2016;Scheben et al, 2017;Carlson et al, 2019;Loskutov, 2021).…”

Background. In order to fully reveal the advantages of a cultivar and use it effectively in production, it is necessary to ensure high sowing and varietal qualities of seeds, which requires improvement in breeding and seed production. Biotechnological methods are increasingly used in initial seed production. High efficiency was shown by the method of electrophoresis of seed storage proteins – prolamins. The aim of this study was to assess the biotype composition and allelic state of the prolamin-coding loci in the new spring oat cultivar ‘Tobolyak’ for its further use in initial seed production.Materials and methods. In 2021, 1519 families of cv. ‘Tobolyak’ were studied using the method of native electrophoresis. Three grains from each family were selected for analyses by random sampling. Electrophoresis was carried out in vertical plates of 13.2% polyacrylamide gel at a constant voltage of 500 V for 4.5–5.0 hours.Results and conclusion. The study of cv. ‘Tobolyak’ families resulted in identifying 13 types of avenin patterns with a frequency of occurrence from 96.36 to 0.07%. A new block of avenin components controlled by the allele of the Avn B locus was described. Number 8 was assigned to this block. It was established that cv. ‘Tobolyak’ had been developed by crossing a minor biotype of cv. ‘Taezhnik’ (Avn 4.4.2) with the first biotype of cv. ‘Orion’ (Avn 2.8.2). The basis of cv. ‘Tobolyak’ was one genotype with the Avn 4.8.2 avenin formula. The remaining biotypes arose as a result of crossing the biotypes of cvs. ‘Taezhnik’ and ‘Orion’ as well as through mechanical contamination. To maintain the genetic stability of cv. ‘Tobolyak’, it is recommended to use only families of the first biotype in the process of original seed production.
