Abstract
The present invention is a new and distinct primocane fruiting red raspberry cultivar named ‘Marcianna’, which is capable of producing large, bright colored, flavorful and firm fruit that has exceptional consumer appeal characteristics. The cultivar is characterized by its leaf pattern change near and after flower initiation on primocanes, its strong and distinctive flavor and firmness and its fruit morphology, specifically its slight imperfections from conic shape. These imperfections include a slight distension and a small bend in its apparent longitudinal axis. ‘Marcianna’ plants are also unusual in that they produce commercial quantities of large, firm and flavorful fruit in both the fall on primocanes and spring on overwintered floricanes. The floricanes are productive with as little as 250 chilling hours in Spain.
