From the standpoint of genetic analysis, umbel and seedling formation were investigated in Japanese bunching onion. Plants were transplanted at a juvenile stage after overwintering. Two kinds of genetic male sterility ((1) S and TO (S)) and their parent lines were used in the present experiment. Each plant of two groups of lines formed the umbels and produced seeds after selfing with paper bags. The umbel and seedling formation of progeny strains from the (1) S and the rate of their parrent lines showed 88.6〜100% and 89.5〜100%, respectively. Those from the TO (S) and their parent strains indicated 94.9〜90.0% and 93.3〜100%, respectively. Therefore, the umbel and seedling formations did not significant differences between (1) S and TO (S) groups. The seedlings after germination were obtained enough to test a segregation ratio for the genetic characters of next generation.
