Citrus x aurantium L., pro sp. [Sweet 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: "This Florida variety was found in 1939 by D. J. Nicholson of Orlando as a budded tree in an old orchard of mixed varieties near Sanford. It was named, patented (U.S. Plant Patent No. 625), and released in 1944."
The Chiefland Budwood Facility (2010) provided the following notes on the cultivar (clone DPI-58): "Dream was found as a budded tree in a Seminole county near Sanford in a grove by D. J Dream. The original tree was discovered in 1939 when it was approximately 25-30 years old. Most likely a bud mutation from Washington. Dream was patented by him in 1944. The origin of the Dream clone entered into the Florida budwood program is from budwood from Nicholson nursery’s mother tree in Orlando which was the source for Barfield groves located north of Lake Alfred. The Florida Citrus Budwood Registration Program entered two parent candidates from the Barfield property, which were virus and viroid infected. A shoot-tip graft selection from the Barfield parent is the one currently used in the Florida budwood program. The budwood program clone was entered into the program in 1975 and is identified as (DPI-58)."
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 (7-10), yellow-orange (11), orange (12), or red-orange (13); rind texture slightly rough (4-5); firmness leathery; navel present; flesh orange; taste acidic-sweet.
Hodgson (1967) provided the following additional information on the cultivar: "Fruit medium-sized, subglobose to spherical; navel medium to medium-large; rind smooth, well-colored, and of medium thickness. Flesh texture moderately soft; flavor rich and sweet (less acid than most navels). Early in maturity and in Florida holds on tree better than most navels without loss of internal quality."
The Chiefland Budwood Facility (2010) provided the following notes on the cultivar (clone DPI-58): "The fruit is high quality, medium size, smaller than some Florida navels, early maturing, average brix/acid ratios, and has an open non-protruding navel. Holds on tree better than most Navels. Like most navels its does not do well on rough Lemon rootstock."
