Abstract
A new and distinct floricane fruiting red raspberry, Rubus idaeus L., variety is described. The variety results from selection among a population of seedlings derived from controlled pollination crossing of the raspberry varieties known as ‘Chilcotin’ (not patented) and ‘Waimea’ (not patented). The fruit of this new variety has an attractive appearance characterized by uniformly large berry size, good fruit firmness, and medium-red fruit color. The new variety is distinguished from others by its high yields of firm, attractive, uniformly sized, large, red berries that ripen in the mid season. The plant exhibits a semi spine-free upright growth habit, of strong vigor. In addition, the plant has displayed resistance to Raspberry Bushy Dwarf Virus (RBDV) under New Zealand conditions. Fruit of the new variety appears suitable for the fresh fruit market. The variety has been named ‘Korpiko’.
