Notes and observations

EMN, 3/23/1987: Fruit appears to be very similar and possibly identical to CRC 3650, Entre Fina.

EMN, 2/4/1988: Blood oranges compared for color; 10 fruit each: Refer back to the card for a Table. This accession (CRC 3152), other than a few flecks of blood, is a typical mid season sweet orange in appearance and flavor. Few seeds.

Description from The Citrus Industry Vol. 1 (1967)

"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.

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.

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."
