Source: Received as budwood from Rubidoux variety block, 1914.

 

Parentage/origins: Apparently a limb sport of Washington navel orange.

 

Rootstocks of accession: Carrizo citrange, C-35 citrange

 

Season of ripeness at Riverside: December to January

 

Notes and observations:

EMN, 1985: Fruits somewhat ridged. This accession had psorosis, removed by thermotherapy (Thermo 1273-28).

EMN, 2/12/1988: Trees are small and appear to be weak growing. Light rind color but most fruits have 1 to 3 thin, raised, darker orange "ribs" running the length of the fruit. TCI, on pp 485-486, describes these "ribs" so this is not a budwood mixup with CRC 609, McFadden Ribbed navel which exhibits no ribs at all, like I thought it might be. Rind of this accession may be somewhat thinner than most navels; otherwise fruit is navel-like inside.

 

Description from The Citrus Industry Vol. 1 (1967):

"Fruit oblong to ellipsoid; apex nipple-like, containing a closed navel; rind very smooth, thin, and leathery. Yellowish-orange colored, with occasional narrow orange streaks or ribs. Matures considerably earlier than Washington.
      Tree slow-growing, small, and weak.
      Buckeye is reported to have originated in California as a limb sport of Washington. It was introduced in 1903 by the R. M. Teague Nurseries of San Dimas. This weak-growing and chimeric variety has never attained much commercial importance"

Availability: Not commercially available in California.
