A citrus hybrid is typically a somatic hybrid within the genus citrus, thus, combining two different citrus varieties or species into one, in order to get intermediate traits or the most desirable traits of both parents. This is done by plant breeding which is also called cross pollination. The selection of the progeny of the new hybrid into a new variety is called hybrid speciation. Citrus hybrids are usually marked with the "×" after the word "Citrus", for example Citrus × aurantifolia.
