Cultivar or taxon

Citrus reticulata Blanco [Satsuma Group] (sensu Swingle and Reece 1967, Mabberley 1997); Citrus unshiu Marcov. (sensu Hodgson 1967; sensu Tanaka sec. Cottin 2002)

Origin

Hodgson (1967) noted that: "Miyagawa originated as a limb sport in a Zairai tree in Fukuoka Prefecture and was named and introduced by Dr. Tyôzaburô Tanaka in 1923. It is currently the best known and much the most extensively grown of the Wase varieties."

Description

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 narrow, adjoining the blade. Leaflets one, margin bluntly toothed, shade leaflet blades flat or weakly conduplicate, sun leaflet blades weakly or strongly conduplicate. Scent of crushed leaflets mandarin-like. Fruit broader than long, 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 absent; flesh orange.

Hodgson (1967) provided the following additional notes on the cultivar:

"Fruit large (for satsuma), moderately oblate, with thin and smooth rind. Seedless. Juice abundant, sugars and acid well-blended, and quality excellent. Matures very early and stores well for Wase Unshû.

Tree more vigorous than most old Wase clones and productive."
