Parentage/origins: Parents unknown.
Rootstocks of accession: Carrizo citrange, C-35 citrange
Season of ripeness at Riverside: January to March
Notes and observations:
1/1989, EMN: Also came in as budwood import, see CRC 3981.
6/1989, EMN: Noted on original USDA spec. list as "salt tolerant".
8/1989, EMN: Additional info regarding Zhuluan received from Dr. Bitters this month: Vermillion Globe sour orange, may be a sour orange hybrid. Supposedly salt tolerant. But it is used as a rootstock in Chejlaing where tangerine varieties grow well on it. Since tristeza is indiginous to China, it may be like Goutoucheng, this has some tristeza tolerance.
3/3/2008, DK & TS: Typical sour orange, with seedy, tender flesh. DK thinks it’s less sour than Seville.
Availability: Not commercially available in California.
