%X Oryza meyeriana Baill is one of the three wild rice species found in Chiia.O. mcyeriana possesses valuable characteristics but is reluctant in cell culturein vitro. In a series of experiments, callus with no regeneration ability was induced from young panicle ofO. meyeriana. The callus was subcultured and propagated. Embryogenic cell clones were obtained after cryopreswation. Suspension cultures were established and protoplasts were isolated and regenerated into plants. Results of artificial inoculation ofXanthomonas campestris pv.Oryzae showed that the strong resistance did not change in the regenerated plants. The development of protoplast-to-plant system is an important progress towards utilization ofO. meyeriana via cellular engineering. The experiments demonstrated that cryopreservation of plant calli was a new way to obtain embryogenic cell line.
