1. Cold storage tests of canning peaches were con-ducted in C-class storage houses in which tempera-ture was maintained between 0 and 5°C in 1956 and 1957. The varieties used in the tests were Kanto No. 2, No. 12 and No. 14. 2. Peaches stored for three weeks in the cold storage houses lost about 10 percent of their fresh weight. As no increase was obtained in the ratio of canned product to the packed flesh of stored peaches as compared with fresh ones, the loss in weight during cold storage was found to be net loss in canned product. 3. The longer the peaches were kept in cold storage, the more the deterioration in their flavor was. Off flavor was detected in the peaches stored for long period, though it was not clear that the off flavor was induced by physiological change in the fruits or by the conditions of the cold storage houses. 4. Among the varieties tested, Kanto No. 12 was. best in keeping quality, while no difference in keeping quality was found between the other two vari-eties. 5. The safe range of cold storage period of canning peaches during which their canning quality was retained without deterioration was 2_??_3 weeks, though it might be varied depending on the conditions of the storage house, handling method of fresh fruits before storing, and variety of canning peach.
