Citrus karna Raf.
Mandarins and their hybrids
December – May
The Khatta is the result of a natural hybridization between an old Mandarin and a Citron, both to be determined. It is native to northeastern India. Its fruits exhibit characters of Citrus jambhiri and sour orange or citron.
TREE AND FRUIT DESCRIPTION:
Vigorous, upright tree. Both young shoots and flowers are purple. Large fruits, variable in shape, but generally round to oval. They may have a wide and prominent apical mamelon. Rind very adherent to the pulp and variable texture: smooth, rough or ribbed. Bright orange color when ripe. Edible albedo, thick, mild flavor, can be somewhat flabby. Pulp scarce, yellow, juicy and very sour taste.
This species is used as rootstock in India. Its juice is used as a substitute for lemon, although its flavor is slightly different, with a predominant sour touch.
