Breeding of New Citrus Scion Varieties

Citrus scion breeding is a long-term project because the process of producing new potential varieties and then evaluating them at several locations in California requires at least two cycles of tree propagation and evaluation. However, the UCR breeding program, which has been funded by the CRB since 1994, is now in a relatively mature phase where the “pipeline” is filled with many new selections at various stages of evaluation.
