‘Prime-Ark® Traveler’ (to be U.S. plant patented as ‘APF-190T’), is the world’s first commercially released, thornless primocane-fruiting blackberry (Rubus L. subgenus Rubus Watson) with shipping-quality fruit. This development is intended primarily as a commercial cultivar to be grown for fruit production for either shipping or local sales. It likely will have value as a home-garden plant also. This is the fifth in the University of Arkansas Prime-Ark® Brand Primocane-Fruiting Blackberry cultivar line following the release of ‘Prime-Jan®’ and ‘Prime-Jim®’ in 2004 (Clark et al., 2005), ‘Prime-Ark® 45’ in 2009 (Clark and Perkins-Veazie, 2011), and ‘Prime-Ark® Freedom’ in 2013 (Clark, 2014). This unique type of blackberry fruits on current-season canes (primocanes) and on second-season canes (floricanes), potentially providing for two cropping seasons, both traditional summer fruits in addition to late-summer to fall production. In addition to having thornless canes, this new introduction produces high-quality berries of medium-large size with good flavor, and potential for shipping and postharvest storage. It is anticipated that ‘Prime-Ark® Traveler’ will complement ‘Prime-Ark® 45’ in the expansion of production of primocane-fruiting blackberries in the United States and potentially worldwide.
