First commercial cultivar of primocane-fruiting blackberry
Prime-Jan (patented as APF-8) was the first commercial cultivars of primocane-fruiting blackberry. This type of fruiting habit has the potential to revolutionize blackberry production much-like that occurring in primocane-fruiting red raspberries. This blackberry variety was intended primarily for home-garden production and for limited commercial trial evaluations. The source of the primocane-fruiting trait in this cultivar was the deploid cultivar Hillquist. Name of Prime-Jan was selected to... read more

Very productive thorny trailing blackberry variety for processing and fresh market
The primary goal of the US Department of Agriculture–Agricultural Research Service breeding program, in cooperation with Oregon State University, was the development of blackberry cultivars that will complement or replace Marion blackberry. While Marion fruits are ideal for processing, the plants are thorny and trailing, susceptible to winter injury, and were too soft and tender skinned for the fresh market. Black Butte variety, released in 1996, has extremely large fruit, and is early ripening... read more
