Barcelona is an old cultivar widely distributed in Western Europe, probably originating in Spain, and the main cultivar grown in Oregon, USA for the last century.
It is very vigorous, forming a large spreading tree.
The husk, one third longer than the nut, opens and sheds the nut freely.
Barcelona is very resistant to big bud mites (USDA, 2010).
It is susceptible to bacterial blight and is often affected by “brown stain” which causes a large number of misshapen nuts.
It flowers mid-season.
Barcelona is very productive, yielding a medium to large dark brown nut with a shell of medium thickness.
The kernel is often fibrous but blanches moderately well with a good flavour. Percent kernel 39 – 42%.
Excellent quality Barcelona nuts have been produced in Marlborough and Wairarapa but kernel quality declines in cool damp climates due to increased fibre adhering to the kernel.
