Source: Received as seed from H. Chapot, Rabat, Morocco, 1956.
Parentage/origins: Parents unknown
Rootstocks of accession: Carrizo citrange, C-35 citrange
Season of ripeness at Riverside: August to December
Seaons of flowering at Riverside: March to August
Notes and observations:
EMN, 12/22/1987: Has not done well, tree 10 is very poor. Probably this cultivar is not well adapted to the Riverside environment. No fruit yet.
EMN, 2/22/1988: Dr. Bitters thinks this is C. gilletiana, not C. schwein… and that this and CRC 3296 are the same. Trees are poor in the field so a good comparison is not available at this time.
EMN, 4/7/1988: This accession compared with CRC 3296, Citropsis gilletiana, at South Coast Field Station. These two are similar but not totally identical. Tim Williams thinks both are C. gilletiana but are different varieties. We probably don't have true C. schweinfurthii.
EMN, 1/20/1989: Only 1 green fruit found- very much like fruit of CRC 3296.
