Cultivar or taxon

 

Citrus x aurantium L., pro sp. [Blood Orange Group] (sensu Mabberley 1997, Bayer et al. 2009); Citrus sinensis (L.) Osbeck (sensu Swingle and Reece 1967; sensu Tanaka sec. Cottin 2002)

Origin

 

Hodgson (1967) noted that: "This relatively new variety is said to have originated as a lima sport of Doblefina that was found by Balthazar Ferrer at Sagunto, Spain. It has remained a minor variety in Spain, but is currently the leading blood orange variety in Algeria and Morocco. The blood coloration is variable and uncertain and lacking in the Atlantic coastal districts of Morocco."

Description

 

Crown compact or dense, not weeping. First-year twig surface glabrous; second- or third-year twig surface striate; thorns absent or not persistent; prickles absent or not persistent. Petiole glabrous, length medium; wings narrow, adjoining the blade. Leaflets one, margin entire (by misinterpretation) or bluntly toothed, shade leaflet blades flat or weakly conduplicate, sun leaflet blades weakly conduplicate. Scent of crushed leaflets orange-like. Fruit as broad as long or longer than broad; rind yellow-orange (11), orange (12), or red-orange (13); rind texture slightly rough (4-5); firmness leathery; navel absent; flesh orange or red/purplish-tinged; taste acidic-sweet.

Hodgson (1967) provided the following additional notes on the cultivar:

"Fruit medium-large, oval to oblong, often asymmetric; commonly with persistent style or small shallow-embedded navel; seeds few and rudimentary or none. Under favorable conditions external blood coloration good (better than Doblefina). Rind medium-thick, moderately smooth, and not as tightly adherent as in Doblefina. Flesh moderately juicy, but blood coloration commonly poor or lacking. Flavor good. Holds well on tree (very much better than Doblefina) and stores and ships as well or better. Late midseason in maturity.

Tree lacking in vigor, small, very precocious, and productive."
