Grapes (large seed strains)were treated with fumigation using SO\ulcorner and seal-packaged by PE film, then storage at 0 at 90 RH for the test of storage life. The fruits weight loss and abnormal fruits increased with storage. The abnormal fruits were rapidly produced after 80 days, however, these rates of Rubel muscat and Shingyoku were only 8.0 and 8.3%, respectively. After 90 days, the rate of Rubel muscat was 19.1%, resulting in the least rate. Moisture content of Kaiji and Honey black slightly increased and that of other grapes decreased. Soluble solids content and acidity decreased except Shingyoku and Honey black, however, sugar/acid ratio increased with these strains. The external appearances were depressed with storage but sensory test value of Shingyoku, Honey black, Rubel muscat were ranged from 7 to 9, showing good evaluation. The hardness of Honey black after 90 days resulted in the highest value 0.51 and that of Izunishiki and Kaiji were 0.23-0.25, showing the least value.
