Storage life of grape cultivars including Kyoho(Inzuka), which were imported from Japan and are cultivated after adoption as farming application, were examined. The stu요 was accomplished with grapes packed by PE film under storage temperature and humidity 90%RH loss of weight, Weight loss and occurrence of abnormal fruit increased in proportion to storage days. Abnormal fruits of Kyoho(izuka), North Black , and Seto giants increased rapidly after 60 days of storage, resulting in slight deterioration of commercial value. Similarly, this phenomenon of Campbell early , Takasumi , and Aki Queen occurred after 70 days of storage. External appearance decreased rapidly after 60 days of storage, resulting in 7.0 index of Takatsuma and Aki Queen , 3.0-3.6 of North Black and Seto Giants, and 5.0 of Campbell Early, kyoho (izuka0, and takasumi after 80 days of storage. Soluble solide content and titratable acidity showed a trend to be decreased with lapse of storage. Sugar/acid ratio shwoed much fluctuation between different grapes. Possible storage days, in view of more 70% merchandise berry ratio, were 90 days of Takatsuma and Aki Queen , 70 days of Campbell Early, 60 days of Takasumi , kyoho(Iizuka), and Seto giants, below 60 days of North Black.
