Abstract
A non-random plastid segregation was found in somatic hybrids of Datura innoxia with seven different Solanaceous species [Atropa belladonna, Datura candida, D. discolor, D. quercifolia, D. sanguinea, D. stramonium and Physalis minima], 14 out of 17 examined somatic hybrids showed the plastid features of Datura innoxia. Within the limits of sensitivity of the applied methods, one line could be shown to contain mixed plstids. Since sexual offspring of this line contains only one set of plastids, it is assumed that this is probably a periclinal chimaera due to the plastome, i.e., the plastid mixture is present on a plant rather than a cell level.
