Nomenclatural standards of oat cultivars of West Siberian selection

The work is devoted to oats – a common grain crop in agricultural production. Oats occupy the fifth place in the world’s grain production and differ from other cereals in a wide range of uses and increased nutritional value. Every year, Russian breeders create and add to the state cultivar testing new cultivars of spring oats, both filmy and naked forms. Nomenclatural standards are created to confirm the originality of the breeding achievement and the copyright of the right holder. Nomenclatural standards are type herbaria to which the name of a cultivar or group of cultivars is permanently attached after promulgation. Such a herbarium specimen can be used as a reference for genetic expertise. As part of the work, herbariа of the spring oat cultivar ‘Maruchak’ (bred by the Kemerovo Research Institute of Agriculture – branch of the Siberian Federal Scientific Centre of Agro-BioTechnologies of the Russian Academy of Sciences together with the Federal Altai Scientific Center for Agrobiotechnology) and ‘Ofenya’ (bred by the Kemerovo Research Institute of Agriculture – branch of the Siberian Federal Scientific Centre of Agro-BioTechnologies of the Russian Academy of Sciences) are performed. Morphobiological descriptions and economically valuable characteristics of the cultivars and information about the history of oat breeding in Western Siberia are given. The plant material for the mounting of the herbarium was collected in the experimental plots of the "Pushkin and Pavlovsky laboratories of the VIR". The nomenclatural standards of each cultivar are mounted on one herbarium sheet and have three herbarium doublet sheets. All herbarium sheets show plants in the stage of milky ripeness, mature inflorescences and fruits. The samples collected for the herbarium are plants grown from a single seed sample. The herbaria were prepared and mounted in accordance with the recommendations of the International Code of Nomenclatural of Cultivated Plants (ICNCP). The herbarium specimens were registered in the VIR Herbarium database and are stored in the Herbarium of Cultivated Plants of the World, their Wild Relatives and Weeds (WIR), in the National Centre for Plant Genetic Resources.
