Creation and introduction of winter-hardy and productive varieties for grain and grain-forage use is one of the top-priority tasks in the field of agricultural production. Winter triticale, combining the traits of both parental taxa – rye and wheat, meets these criteria, forming a high yield of grain and green mass, has resistance to common diseases. A new promising variety of hexaploid winter triticale ‘Bilinda’ for grain-forage use was obtained by intervarietal hybridization of hexaploid triticale varieties using individual-mass selection from the hybrid population. ‘Bilinda’ is characterized by high uniformity, high yield, large grain, resistance to most leaf diseases and more pronounced winter hardiness compared to the standard. This triticale variety is characterized by unique combinations of stable morphological traits that can be effectively used as markers in breeding selections. The isolation of the first elite plant dates back to 2004; in 2019, the variety ‘Bilinda’ was included in the State Register of Breeding Achievements and zoned in 2020 for the Northwestern region of Russia. Based on the rules given in the International Code of Nomenclature of Cultivated Plants, in 2023, we carried out the work on creating the nomenclature standard of winter triticale variety ‘Bilinda’, bred in Leningrad Research Agriculture Institute – Branch of Russian Potato Research Centre on the basis of VIR triticale collection. We collected plants in the phase of milk ripeness together with the staff of the Herbarium of cultivated plants of the world, their wild relatives and weedy plants of the N.I. Vavilov All-Russian Institute of Plant Genetic Resources in the field of NPB “Pushkin and Pavlovsk laboratories of VIR”, Pushkin. We carried out herbarization according to the methodological instructions. The nomenclatural standard was supplemented with ears and grains from the originator, duplicated on seven sheets and transferred for storage to the Herbarium of cultivated plants of the world, their wild relatives and weeds (WIR) and the National Plant Genetic Resource Center of Russia
