We bred the good-tasting kiwifruit cultivar 'Shizuoka Gold,' which enables it to sell in the Christmas season. Sugar content of the 'Shizuoka Gold' fruit was more than 17 Brix its citric acid levels were 1.2%. The fruits have an excellent balance of sugar and citric acid. The harvesting period was from early to mid-October and occurred about 3 weeks after the 'Rainbow Red' harvest time. Because 'Shizuoka Gold' can be stored for longer than the 'Rainbow Red,' 'Shizuoka Gold' fruit could be sold during the Christmas season. Disbudding time of 'Shizuoka Gold' was shorter than that of 'Rainbow Red', because the flower number was lesser than that of 'Rainbow Red.' The bacterial canker (strain Psa3) resistant ability of 'Shizuoka Gold' was stronger than that of 'Rainbow Red'. Therefore 'Shizuoka Gold' is a promising cultivar that can be shipped during the Christmas season, which follows the 'Rainbow Red' season.
