Three varieties of Japanese bunching onion (Allium fistulosum L.) were evaluated for excess water tolerance. In the experimentl, plants were grown under three kinds of field conditions that were upland field converted from the paddy this year and twenty-five year ago and sandy field. The effect of excess moisture injury for the growing after transplaning were investigated under these conditions. All three varieties decreased plant heights and yields in the upland field converted from the paddy this year. So excess moisture injury in all varieties was large that we could not clarify the water tolerance in the field converted from the paddy. In the experiment II, plants were raised in 1/5000 wagner pot with vermiculite and paddy soil in a vinyl house. Three levels of moisture conditions were used as water treatments. The difference of excess water tolerance between varieties was recognized in the experiment II. Therefore, the selection for its tolerance may be possible in Japanese bunching onion.
