Source: Received as seed from Dr. W.P. Bitters, 1963.

Parentage/origins: Sudachi is thought to be a hybrid of C. ichangensis and C. reticulata. This accession came from Okitsu, Shizuoka Pref., Japan.

Rootstocks of accession: Carrizo citrange, C-35 citrange

Season of ripeness at Riverside: When used for cooking purposes, Sudachi is harvested while still green which occurs during September to October.

Notes and observations:

1961, TT: A Yuzu relative that may be worth calling "Mandarin-Junos" of Japan which is exclusively used for acid juice. Few seeds, rind 3.5 mm thick.

1963, WPB: Small fruit somewhat resembling Yuzu. Fruit is reddish-orange, leaves similar to Yuzu, resistance of sudachi to citrus canker is good & gummosis resistance is good. Highly resistant to citrus root borer. Growth is slow, may have dwarfing characteristics. Trees are long-lived. Sudachi is an acid citrus; it bears small fruit (20-25 g) and is traditionally grown in Tokushima Prefecture (Japan). The fruit are harvested only at the green stage and are served in cut halves as a garnish. Polyembryonic.

2/26/1988, EMN: Tree with extremely large crop of marble-shaped fruits. Way past maturity now but still on tree; mummies from past year indicate that the fruit never drop.

Availability: Commerically available in California through the Citrus Clonal Protection Program.
