Rapeseed (Brassica napus L. var. napus, syn. Brassica napus L. subsp. oleifera Metzger) is the main oilseed crop in the temperate zone. As part of the work, we prepared a nomenclatural standard of spring rapeseed cultivar Brassica napus L. ՙOredezh 6՚of the selection of Leningrad Research Institute for Agriculture “Belogorka” – branch of the Federal State Budgetary Scientific Institution “A.G. Lorkh Federal Research Center of Potatoes”. The cultivar is included in the State Register for Selection Achievements Admitted for Usage and recommended for cultivation in the North-West region of Russia. We present descriptions of morpho-biological and economic characteristics of this cultivar and publish its nomenclatural standard for its promulgation, for documentation of the cultivar and replenishment of the national catalog of crops. The International Code of Nomenclature for Cultivated Plants (ICNCP) identifies nomenclatural standard a single item (or entity), preferably a herbarium specimen, to which the name of a cultivar or Group is permanently attached. The relevance of the creation of nomenclatural standards is that they contribute to the cataloging of cultivars of Russian breeding and are applicable both to confirm the originality and to protect the breeding achievement of the originators. Plant material for the herbarium of the nomenclatural standard of spring rapeseed cultivar ՙOredezh 6՚ was grown and collected at the experimental field of the Pushkin and Pavlovsk laboratories of VIR (Saint Petersburg). The plants were collected according to the methodology “Herbarization of cultivated plants”. The nomenclatural standard was prepared in accordance with ICNCP recommendations, registered in the VIR Herbarium database and is deposited at the Herbarium of Cultivated Plants of the World, their Wild Relatives and Weeds (WIR), at the National Center for Plant Genetic Resources
