We selected two malesterile sugi (Cryptomeria japonica D. Don) trees (M-1, M-2) from 10, 902 Tateyama-sugi seedlings. By observation, both male and female flowers appeared to be almost normal. However, no pollen grains were dispersed from the male flowers in pollination season. The inside structures of the male flowers appeared to be quite different from normal flowers under a scanning electron microscope. The open-pollinated seeds obtained from M-2 had normal germination ability, but the seeds of M-1 showed a low level of germination. The chromosome numbers of the two male sterile trees were 22, euploid. So, it was inferred that the characteristic is caused by the male sterile gene and this mutation occurrs at a frequency of 0.016 to 0.002% in sugi (Cryptomeria japonica D. Don). This selection method is effective because male sterile trees can be selected in few cultivation areas and short terms.
