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 Atwood: "According to Opitz (1962), Atwood originated as a limb sport in the orchard of Frank Atwood near Lemon Cove, California, and was first noticed about 1935."

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, adjoining the blade. Leaflets one, margins bluntly toothed, shade leaflet blades weakly conduplicate, sun leaflet blades weakly conduplicate. Leaflets sweetly orange-like when crushed. 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.

Notes

 

Hodgson (1967) additionally indicated that: "The fruit and tree of the Atwood navel orange variety are virtually indistinguishable from the parent variety, Washington. The fruit colors slightly earlier and the rind surface appears to be somewhat smoother, however. While earlier maturity is suggested by its coloring behavior, the fruit stores on the tree especially well without appreciable loss of quality. During the early part of the season, however, its quality is not quite as good as that of the parent variety....It is considered to be promising in central California and has been planted to some extent there in recent years."
