Bream, Taracco, Tarocco Dalmuso, Tarocco del Francofonte, Tarocco del Muso, Tarocco Dolnus, Tarocco Francofonte, Tarocco Messina, Tarocco Rosso (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: "The name of this comparatively new Italian variety, the English equivalent of which is the peg-top toy, is said to have come from the pronounced basal collar that is characteristic of fruits of the original clone. Scarcely three decades after its discovery, however, Casella (1935) distinguished three types or clones, of which that known as Tarocchino is now considered to be the variety Ovaletto Sanguigno (Chapot 1963)."
The Chiefland Budwood Facility (2010) provided the following notes on the cultivar (clone DPI-441-18/DPI-441-37): "The budwood program’s parent trees originated in research block of Dr. Bill Castle on the property of Orie Lee in St. Cloud. Entered into the program in 1995."
Crown compact or dense, not weeping. First-year twig surface glabrous; second- or third-year twig surface striate; thorns straight; prickles absent or not persistent. Petiole glabrous, length medium; wings medium, adjoining the blade. Leaflets one, margin entire (by misinterpretation) or bluntly toothed, shade leaflet blades weakly conduplicate, sun leaflet blades weakly 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 smooth (1-3) or slightly rough (4-5); firmness leathery; navel absent; flesh orange or red/purplish-tinged; taste acidic-sweet.
Hodgson (1967) provided the following additional notes on the cultivar:
"Fruit medium-large to large, variable in form from broadly obovate to globose; commonly with broad, pronounced, and furrowed basal collar; few or no seeds, the chalazal spots of which are purplish-red. Yellowish-orange, blushed with red at full maturity. Rind medium to medium-thick, moderately tightly adherent, and finely to moderately pebbled. Flesh somewhat firm but juicy, usually well pigmented; flavor rich and sprightly. Midseason in maturity (somewhat later than Moro and Ovaletto). Loses quality if left on tree much past maturity and drops badly, but ships and stores well.
Tree moderately vigorous, medium in size and irregular in form; foliage rather open, consisting of highly variable leaves, mainly oval-elliptical and sharp-pointed. Sensitive to wind and neglect; only moderately productive."
The Chiefland Budwood Facility (2010) provided the following additional notes on the cultivar (clone DPI-441-18/DPI-441-37): "Less color than Moro."
The Chiefland Budwood Facility (2010) provided the following additional notes on the cultivar (clone DPI-441-18/DPI-441-37): "Tarocco is grown in Italy and other cool citrus climates for optimal color development."
