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

 

Hodgson (1967) provided the following notes on the origin of Carter: "Presumed to be a bud variation of unknown origin, a number of old trees of this variety were noted about 1925 in the A. N. Carter orchard at Sierra Madre, California. The variety was introduced by the Armstrong Nurseries of Ontario, California in 1928 and recommended for home planting. It is still in demand in California and has been planted to some extent elsewhere."

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; wings medium, adjoining the blade. Leaflets one, margin 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 slightly rough (4-5); firmness leathery; navel present; flesh orange; taste acidic-sweet.

Hodgson (1967) provided the following notes on this cultivar: "Both the tree and fruit of this California variety are so similar to Washington that they are indistinguishable. Grown under the same conditions, however, the rind of Carter appears to be somewhat smoother and thinner, the flesh texture a little less firm and juicier, and the flavor somewhat sweeter (less tart). Carter is also slightly earlier in maturity."
