In scientific literature and genetic resource collections, Malus × robusta «Erecta» is mentioned — an apple form with a vertical crown type, which is sometimes used as a rootstock or a decorative element. Fruits of such forms are usually small, about 2.3 cm in size, their color varies from yellow to dark purple, and flowering can be periodic.
In generally accepted registries of Malus domestica varieties, a variety named «Erecta» does not exist. In genetics, the name ERECTA refers to a gene that regulates plant architecture. Often, under this name, nurseries sell Berberis thunbergii «Erecta», which possesses a narrow columnar crown.
