Synonyms

 

Robles (sec. Cottin 2002)

Cultivar or taxon

 

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)

Origin

 

The Chiefland Budwood Facility (2010) provided the following notes on the cultivar (clone 502-4-12): "This clonal selection that was made at the Pless Nursery in Thonotosassa in Hillsborough County and entered into the budwood program in 1970. Joseph Robles obtained seed from Madrid Spain after 1851 and planted a grove in Tampa. His son, Green Robles, later planted a seedling grove from the strain. Leon Hanna obtained budwood from Green’s grove and planted his own grove around 1900, naming the variety after Joseph. Roble is probably as early in maturity as the Parson Brown."

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 medium; wings narrow or medium, 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 green-yellow (6), yellow (7-10), yellow-orange (11), or orange (12); rind texture slightly rough (4-5); firmness leathery; navel absent; flesh orange; taste acidic-sweet.

The Chiefland Budwood Facility (2010) provided the following additional notes on the cultivar (clone 502-4-12): "Seediness and juice color are equal to the Parson. Solids are competitive with the Valencia orange on sour orange rootstock. The peel is orange in color with a thick and rough texture like the Parson. The acid drops rapidly once it is past maturity."

Notes

 

The Chiefland Budwood Facility (2010) provided the following notes on the cultivar (clone 502-4-12): "Roble is not recommended to be budded on Swingle or other trifoliate hybrid type rootstocks."
