OriginUSA

The citrange (Citrus sinensis × Poncirus trifoliata or C. sinensis × C. trifoliata) is a citrus hybrid of the sweet orange and the trifoliate orange.

The purpose of this cross was to attempt to create a cold hardy citrus tree (which is the nature of a trifoliate), with delicious fruit like those of the sweet orange. However, citranges are generally bitter.

Citrange is used as a rootstock for citrus in Morocco, but is not successful to prevent dry root rot, neither for exocortis.[1]

Cultivars

There is a carrizo citrange[2] and there is a troyer citrange.[3] Both are resulting of a hybrid between the trifoliate orange and the Washington navel orange. There is also a cultivar called Rusk which is resulting from a cross between a Ruby orange and a trifoliate orange.[4][5]
