Blackberry plant named ‘Columbia Star’

Abstract

A new and distinct blackberry cultivar that originated from seed produced from a cross between the female blackberry plant ‘NZ 9629-1’ (unpatented) and the male parent blackberry plant ‘ORUS 1350-2’ (unpatented). This new blackberry cultivar can be distinguished by its high yields of large, very uniformly shaped berries with very good flavor, sweetness, and fruit chemistry as characterized by soluble solids, pH, and titratable acidity that make them well suited for processing. The new and distinct blackberry variety has fruit that are borne on vigorous, completely thornless plants and can be harvested by machine.
