Source: Received and grown by R. K. Soost from China, 1985.

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.
