Source: Received as seed from seedling from Rubidoux Tract tree of unknown origin, 1915.
Parentage/origins: Parents unknown.
Rootstocks of accession: Carrizo citrange, C-35 citrange
Season of ripeness at Riverside: December to January
Notes and observations:
EMN, 12/7/1989: Originated from seed 1915. This accession had psorosis which was eliminated by thermotherapy (Thrmo 1176-5) This appears to be an ordinary navel with no special attributes. Why keep it if it hasn't become a national landmark yet?
EMN, 12/7/1989: STOP! DON'T DISCARD YET! Is among best yielding strains in "navel yields in smog" experiment in the Rubidoux screenhouse.
Availability: Not commercially available in California.
