Citrange: A Citrus Hybrid

The citrange is a fascinating citrus hybrid created by crossbreeding the sweet orange (Citrus sinensis) with the trifoliate orange (Poncirus trifoliata). The initial motivation behind this cross was to produce a citrus tree that could withstand colder temperatures.

  • Common Name(s): Citrange
  • Synonyms/Varieties: Rusk Citrange, Spaneet Citrange, Troyer Citrange, Troyer Rangpur, Willits Citrange, Citrangedin Glen, Citrandarin, Citradia, Citremon, Citrumelo, Benton Citrange, C-35 Citrange, C-13 Citrange

Origin and Purpose

Citranges, such as Troyer and Carrizo, originated from crosses made in the early 1900s. They are hybrids of the Washington navel orange and Poncirus trifoliata, bred to create cold-hardy citrus rootstocks.

Uses

Citranges are more aromatic and acidic than typical oranges. While they can be used in beverages and marmalade, they're often cultivated as rootstocks for other citrus varieties due to their hardiness and disease resistance.

Research and Applications

  • Citrange, particularly the Carrizo variety, has been used in research to study salinity tolerance in citrus. Transgenic Carrizo citrange rootstocks have been developed to overexpress glyoxalase I and glyoxalase II genes to improve their ability to withstand salty conditions.
  • Carrizo citrange has also been used in studies examining chloride absorption in citrus rootstocks.
