[Sweet Orange Group]] (sensu Mabberley 1997, 2004); Citrus reticulata Blanco x Citrus sinensis (L.) Osbeck (sensu Swingle and Reece 1967; sensu Tanaka sec. Cottin 2002); Citrus sinensis (L.) Osbeck x Citrus tangerina Yu. Tanaka (sec. NPGS/GRIN 2010)

Origin

 

Hodgson (1967) noted that: "The Dweet tangor, currently on trial in Califomia[sic], is of Mediterranean Sweet orange and Dancy tangerine parentage. This synthetic tangor resulted from the breeding experiments of H. B. Frost of the University of California Citrus Research Center, Riverside. It was selected in 1930 and introduced in 1950."

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 short; wings absent, if present, medium, adjoining the blade or tucking beneath blade. Leaflets one, margin entire or bluntly toothed, shade leaflet blades flat or 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 (7-10), yellow-orange (11), orange (12), or red-orange (13); rind texture slightly rough (4-5) or medium rough (6-7); firmness leathery, navel absent; flesh orange; taste acidic-sweet.

Hodgson (1967) provided the following additional information on the cultivar: "Fruit medium-large, reddish-orange, globose to oblate-necked, and moderately pebbled. Rind peels poorly and tends to puff. Seedy, very juicy, and of rich flavor. Matures late. Does not hold well on tree, but good for home use."
