This study was to examine the variations of chromosome number and the ranges of variety in the suspension culture of ginseng (Panax ginseng C. A. Meyer) callus cell, and the effect of plant hormones for the chromosome aberration. Plant hormones added with MS medium in the suspension culture were 2,4-D, kinetin, and 2,4-D+kinetin and concentration of the plant hormones were 1000 μM, 10 μM and 0.1 μM respectively. As a result of these experiment the following conclusion has been obtained. Media contained with 2,4-D+kinetin in 10 μM concentration was very effective in the suspension culture result from 26.4% mitosis frequency, and found the various variation of chromosome number. Variety of chromosome number was diversed (9～110), espicially frequency of hypohaploid and hyperhaploid cells were very higher than hyperdiploid cells. In this experiments, it is suggested that 10 μM 2,4-D+kinetin added with medium in the suspension culture of ginseng callus was effect in the variations of chromosome number.
