‘NR7’ is a new floricane-fruiting red raspberry (Rubus idaeus L.) cultivar from The New Zealand Institute for Plant & Food Research Limited (PFR) and Northwest Plant Company (NWP) joint raspberry breeding program. It is owned by Pacific Berries LLC and marketed as ‘Raspberry Shortcake®’ in the United States and Canada and ‘Ruby Beauty®’ in the United Kingdom and Europe. In this article we describe the origin and selection process of this new cultivar, its characteristics, and use. It was derived from a family from controlled crosses between HR101 and ‘Willamette’. ‘NR7’ is a fully dwarf spineless plant that produces medium- to large-sized fruit in the early-midseason and is well suited to ornamental applications such as home gardens and containers. ‘NR7’ plants appear to have some tolerance to Raspberry bushy dwarf virus (RBDV) but are susceptible to mites.
