Fruits & Vegetables Week: Citrus sinensis, naval orange

[Gurcharan Singh]

Citrus sinensis, naval orange, also known as the Washington, Riverside, or Bahia navel. This seedless fruit was a result of mutation, the mutation causes the orange to develop a second orange at the base of the original fruit, opposite the stem, as a conjoined twin in a set of smaller segments embedded within the peel of the larger orange. From the outside, it looks similar to the human navel, hence its nam. Being sterile and seedless, it can be propagated only by grafting it on other hardy varieties. Because the mutation left the fruit seedless, and therefore sterile, the only means available to cultivate more of this new variety is to graft cuttings onto other varieties of citrus tree.
