Citrus sinensis (L.) Osbeck RUTACEAE
Received as seed from Dr. Cooper, Delta Lake, Texas, 1958.
From double seedlings; originally imported from Morocco as budwood.
Rootstocks of accession
Carrizo citrange, C-35 citrange
Season of ripeness at Riverside
January to March
Notes and observations
So far the Precoce sweet orange has not come down with Phytophthora in Cooper's rootstock planting at Delta Lake. It is one of the highest producing stocks in this planting.--J.Furr.
1987, EMN: According to TCI, Vol. I, pp 444, "Precoce de Valence" is a synonym for Cadenera. Is this what this is?
2/8/1988, EMN: Apparently old card name: "Precoce de Valencia" was in error. should be "Precoce de Valence" S/A ratio in Jan. '87 was very high. A comparison was made of fruit of this accession with CRC 2856, Cadenera Fina, and CRC 3632, Cadenera. This accession is similar but not identical to those two; it has better rind color on average, rougher rind, may be slightly larger, has more seeds.
Description from The Citrus Industry Vol. 1 (1967)
"Fruit medium-sized, globose to slightly oval; apex somewhat depressed; areole ring faint or lacking; seeds few or none. Moderately well-colored. Rind medium-thin and surface smooth to finely pebbled. Flesh very juicy and flavor and aroma excellent. Holds well on tree and retains quality. Medium-early in maturity (preceded by Salustiana and Hamlin).
Tree vigorous, hardy, large, and productive.
Of Spanish origin, presumably a chance seedling, Cadenera appears to be the most important variety in Spain, its production being exceeded only by only by comuna, which, as noted earlier, consists of a group of unnamed similar or identical seedling clones. It is important also in Morocco and Algeria and hence ranks high among major orange varieties. Because of its excellent quality, it is well and favorably known in European markets.
Cornice appears to be a selection of Cadenera (Chapot, 1948) but Cadena Punchosa is an inferior variety no longer being planted."
Not commercially available in California.
