Source: Received as budwood from The Citrus Clonal Protection Program in Rubidoux, Ca, from Greenhouse stock plant. Date unknown.

Parentage/origins: This is a selected seedling from the Arizona 861 citron.

Rootstocks of accession: CRC 1449 Citremon, Yuma Ponderosa lemon.

Season of ripeness at Riverside: November to January.

Notes and observations:

12/22/1987, EMN: This is a seedling citron budline produced through CCPP and found to be especially sensitive as an indicator for mild citron viroids. Fruit is much like Etrog but does not have the persistent style associated with true Etrog.

12/5/2006, DK & TS: Typical citron size and elongated egg shape. Flesh seedy, dry, but does have surprising amount of juice, which is tart, but has a bit of sweetness to it. Rind has floral aroma, with some sweetness, but a bitter aftertaste.

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