Nomenclatural standards of gooseberry cultivars developed at the Russian Research Institute of Fruit Crop Breeding

Background. Among the main targets in modern gooseberry breeding are resistance to American powdery mildew and leaf spots, large size of berries, lower thorniness, better fruit taste, high yield, and compact bush habit convenient for mechanized harvesting. Gooseberry cultivars released by the Russian Research Institute of Fruit Crop Breeding (VNIISPK) meet these requirements. This study presents the nomenclatural standards developed for those cultivars. Materials and methods. The bioresource collection of gooseberries maintained at the VNIISPK served as the material for the study. The gooseberry cultivars ‘Diskaveri’, ‘Moryachok’, ‘Nekrasovskiy’, ‘Solnechny Zaychik’ and ‘Yupiter’ participated in the study. Results. Herbarium specimens designed in line with the recommendations of the International Code of Nomenclature for Cultivated Plants (ICNCP) according to the protocol developed at the N.I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR) were appointed as nomenclatural standards. The herbarium label contains: the identification number of the specimen in the VIR Herbarium, the Latin name of the species, the name of the cultivar, its origin (the name of the organization where the cultivar was developed), the place of reproduction (where the plant taken for the herbarium was grown), the dates of collecting, and the names of collectors. Each herbarium specimen is supplemented with photographs of flowers and berries, registered in the VIR Herbarium database, and deposited in the type collection of the Herbarium of Cultivated Plants of the World, Their Wild Relatives, and Weeds (WIR). Conclusion. Scientists of VIR and the VNIISPK devised and published nomenclatural standards for 5 gooseberry cultivars from the VNIISPK. They were included in the collection of nomenclatural standards for crop cultivars of domestic breeding.
