Citrus reticulata Blanco (sensu Swingle and Reece 1967, Mabberley 1997, 2004; sensu Tanaka sec. Cottin 2002); Citrus clementina hort. X Citrus x tangelo J.W. Ingram & H.E. Moore (sec. NPGS/GRIN 2010)

Origin

 

Hodgson (1967) noted that: "This very early maturing, rather large-fruited variety is a sister to Lee and Osceola, all three resulting from a Clementine mandarin-Orlando tangelo cross made by Gardner and Bellows of the U.S. Department of Agriculture in Florida in 1942 and released in 1959 (Reece and Gardner 1959). Robinson is currently under commercial trial in Florida. Since its parents are both self-incompatible and more fruitful if cross-pollinated, it seems likely that Robinson will exhibit the same characteristics."

The Chiefland Budwood Facility (2010) provided the following additional notes on the cultivar (clone SPB-800-3): "Robinson is a USDA hybrid released in 1959. Cross between Clementine and Orlando Tangelo. "

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 or medium; wings narrow, adjoining the blade. Leaflets one, margin crenate/crenulate or bluntly toothed, shade leaflet blades flat or weakly conduplicate, sun leaflet blades weakly conduplicate. Scent of crushed leaflets mandarin-like. Fruit broader than long; rind 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 notes on the cultivar:

 

"Fruit medium-large, oblate (more so than Osceola): base evenly rounded or slightly necked; apex broadly depressed. Rind thin, tough and leathery, moderately adherent but easily peelable: surface smooth and glossy; color deep yellowish-orange at maturity. Segments numerous (12-14), readily separable; axis large and hollow. Flesh color deep orange; juicy; flavor rich and sweet. Seeds moderately numerous and cotyledons light green. Early in maturity (about the same as Lee and Osceola but colors earlier).

 

Tree upright-spreading, nearly thornless; dense foliage consists of large broadly lanceolate, taper-pointed leaves, commonly notched at the tip and crenate-margined on the upper half. Appears to be a regular bearer."

 

The Chiefland Budwood Facility (2010) provided the following additional notes on the cultivar (clone SPB-800-3): "Small to medium size, cold hardy, colors early, moderate seeds. Problems: Thin fruit splits, dries out early, dieback, limb breakage, tree collapse, needs pollinator for best yields (TE, OR/TA, Lee). Season: Early, October-December"
