Notes and observations:

1/1989, EMN: Two other imports from China with names beginning with "X" are sweet oranges; let's take a wild guess and house this one under SWT also.

6/1989, EMN: Original USDA spec. list does say this is C. sinensis. Also says it is "high total soluble solids", and that's all, folks.

8/1989, EMN: Additional info re Xianfengcheng received from Dr. Bitters this month: Sometimes called "Pioneer orange or S20". As a famous sweet orange variety, it has been cultivated for decades in Sichuan Province, the largest citrus producer in PRC. It oringinated as a seedling in Jiangjin County near Chongqing City and was selected by Dr. W. Zhang in early 1930s. Fruit medium sized (wt. 150 to 180 gr. per fruit), obovate to ovale, high total soluble solids, 6.5 seeds per fruit; Ripens at end of Nov. & early Dec. They store it until May. I ate some in May- looked like just off the tree- how do they do that with no controlled storage? Sometimes also called Goose-egg orange.

Availability: Commercially available in California through the Citrus Clonal Protection Program.
