Source: Received as seed from another source on the Riverside Field Station, 1968.

 

Parentage/origins: Open pollinated seedling.

 

Rootstocks of accession: Carrizo citrange, C-35 citrange

 

Season of ripeness at Riverside: November to January

 

Notes and observations:

Fisher is an early-season navel orange cultivar that reaches 8:1 solids to acid ratio ahead of Atwood, Bonanza, Newhall and Washington navel in Lindcove, California, but it does not reach color-break before mid-season cultivars such as Atwood and Washington navel. (Nauer et. al. 1985).  Based on another study, Fisher reaches 8 to 1 solids to acid ratio about the same time as Beck-Earli and Fukumoto, but ahead of Washington navel.

Availability: Not commercially available in California.
