C48-9-6, Fortuna (sec. Cottin 2002)
Citrus reticulata Blanco (sensu Hodgson 1967, Swingle and Reece 1967, Mabberley 1997, 2004; sensu Tanaka sec. Cottin 2002)
Hodgson notes that: "This exceptionally late, high quality, attractive new variety originated from a Clementine X Dancy cross made by J. R. Furr (1964) of the U.S. Department of Agriculture at the U.S. Date and Citrus Station, Indio, California. Fortune was released in 1964 and is recommended for the desert regions of California and Arizona. Provision for cross-pollination is suggested until the facts in that connection are known."
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 or medium; wings narrow, adjoining the blade. Leaflets one, margin crenate/crenulate or bluntly toothed, shade leaflet blades weakly conduplicate, sun leaflet blades weakly or strongly conduplicate. Scent of crushed leaflets mandarin-like. Fruit broader than long, as broad as long, or longer than broad; rind yellow (7-10), yellow-orange (11), orange (12), or red-orange (13); firmness leathery; rind texture slightly rough (4-5); navel absent; flesh orange; taste acidic-sweet.
Hodgson (1967) provides the following additional notes on the cultivar:
"Fruit medium to medium-large, moderately oblate; rind medium-thin, fairly tightly adherent but peelable; surface texture somewhat pebbled; color reddish-orange. Flesh orange-colored; firm but tender and juicy; flavor rich and sprightly (subacid). Seeds numerous, of medium size, and monoembryonic. Late in maturity and fruit holds well on tree with little loss in quality.
Tree vigorous and spreading; dense canopy protects fruit against sunburn and cold; productive."
