Abstract: Protoplasts were isolated from leaf, petiole and stem segment-derived calli induced from one pistillate plant of Actinidia deliciosa line No. 26. Regenerated plantlets were obtained from protoplasts of leaf-derived and stem segment-derived calli, while only calli regenerated from protoplasts of petiole-derived calli. Seventy-six plants from protoplasts of leaf-derived calli and 21 plants from that of stem segment-derived calli survived after transplanting or grafting during 1987–1989. One staminate plant and two pistillate plants bloomed in May, 1991 and fruited soon afterwards. In all of those three plants regenerated from protoplasts of leafderived calli, sex differentiation occurred from somatic cells of Actinidia was verified. Somaclonal variation on leaf shape and plant morphology was obviously appeared. Chromosome number identified from 16 plants varied from 116 to 180.

Key words: Actinidia deliciosa, Regenerted plants dervied from protoplasts, Somaclonal variation
