Abstract

A Nordic-type blackberry variety named "Per Can" combines the characteristics of cold-hardiness, thornless branches and stems, adaptability to various soil conditions, vigor and strength, absence of suckering, and ease of propagation by tissue culturing. Per Can yields berries characterized by an excellent taste (slightly acid, slightly sugary), a very fresh appearance and appealing texture, with a real blackberry aroma and no noticeable aftertaste.
