Blood Oval, Burrado, Condesa, Condessa, Doble Fina, Extrafina, Morlotte, Oval Doblefina, Oval Fino, Oval Sangre, Ovale Sanguigno, Roja, Rojo Oval, Sangre Doble Fina, Sanguina Doble Fina, Sanguigna Oval (sec. Cottin 2002)
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)
Hodgson (1967) noted that: "Of unknown Spanish origin, Doblefina was for many decades the principal blood orange variety in Spain and was favorably known in European markets. It has been losing ground for some years, however, to other varieties of better color and richer flavor, particularly its derivative, Spanish Sanguinelli. It is of interest to note that three blood orange varieties—Entrefina, Doublefine Ameliorée, and Spanish Sanguinelli—have originated as budsports from Doblefina."
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 bluntly toothed, shade leaflet blades weakly conduplicate, sun leaflet blades weakly or strongly conduplicate. Scent of crushed leaflets sweetly 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; taste acidic-sweet.
Hodgson (1967) provided the following additional information on the cultivar:
"Fruit medium-small to small, oval to oblong; virtually seedless. Yellowish orange at maturity, more or less densely blushed with rose-colored flecks. Rind medium-thick, firm and leathery; surface very smooth and fine-textured; tightly adherent (difficult to peel). Flesh firm and moderately juicy, with pink flecks scattered more or less throughout; distinctive fragrance and mild, pleasant flavor. Fruit hangs poorly on tree and drops badly, but ships and stores unusually well. Late midseason in maturity.
Tree small and somewhat lacking in vigor, spreading and open in growth habit; foliage sparser and lighter green than most. An early and heavy bearer."
Hodgson (1967) has additionally noted that: "Aside from its short season, lack of juiciness, and other faults, the Doblefina variety is highly variable and uncertain with respect to development and intensity of the blood coloration, which is often deficient or lacking. When well developed, however, the fruit is attractive."
