Source: Received as budwood from the UCR Breeding program. The crosses were made in 1951 at the University of California Citrus Research Center.

 

Parentage/origins: Both C-35 and C-32 arc F1 hybrids between 'Ruby' orange (CRC 589, NLA) and 'Webber-Fawcett' trifoliate (CRC 2552).

 

Rootstocks of accession: Carrizo citrange

 

Season of ripeness at Riverside: November to January

 

Notes and observations:

TJS: C-32 citrange consistently has a very low seed count and so it has been difficult to collect seed from in order to use as a rootstock.

C-32 is reported to produce vigorous seedling trees and many nucellar seedlings. It has trifoliolate leaves typical of most F1 hybrids between Citrus and Poncirus.

 

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