Blackberry Caddo (Sweet-Ark Caddo) is the fourteenth release in a series of erect-growing, high quality, productive floricane-fruiting blackberry cultivars intended for the fresh market developed by the University of Arkansas Division of Agriculture. It has Prime-Ark 45 in pedigree. Caddo was developed with the intention of advancing flavor to a higher level in an additional thornless blackberry cultivar. Canes of Caddo variety are fully thornless and erect, looks like Natchez. Caddo ripens mid-early season, near Osage and slightly before Ouachita and just after Natchez. Blackberry Caddo produces large berries, larger than that of Osage and Ouachita. Caddo has a flavor very similar to Osage and Natchez, but more sweety. Fruits of blackberry Caddo are oblong and have even drupelet fill. Drupelets are usually visually larger than Ouachita, Osage and Natchez. Berries of Caddo are glossy with a uniform black finish. Fruit firmness is a noteworthy characteristic of Caddo. Average berry weight of Caddo ranged from 7 to 9 g. Yield is excellent, like Natchez. Winter hardiness is about -17 C. Overall, Caddo cultivar appears similar in hardiness to other Arkansas-developed cultivars such as Ouachita and Osage varieties. Caddo should be a commercial cultivar with good potential for shipping, as well as an option for local-market production as well as home gardens.
