Source: Received as budwood from Armstrong Nurseries, Ontario, Ca, 1958.

Parentage/origins: Apparently arose as a bud sport of the Washington navel orange. Fisher was introduced from Armstrong Nurseries who had received it from Mrs. Fisher.

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