Stability of 'Thornless Evergreen' Blackberry in Vitro and Ex Vitro (Tissue Culture, Chimera, Variability, Somaclonal Variation, Rubus)
Abstract
dc:description'Thornless Evergreen', Rubus laciniatus Willd. (2n = 4x = 28), is a periclinal chimeral blackberry in which a mutated thornless epidermis surrounds a core of cells with a thorny genotype. Adventitious shoots from roots are always thorny, and gametes carry the thorny gene. Via micropropagation, pure thornless plants were selected from rapidly propagated shoot tips. These pure thornless plants had shortened internodes and a characteristic "bent petiole" condition. Isolated root segments of pure thornless plants produced thornless adventitious shoots. Micropropagated plants were placed in field plots for evaluation.
