Breeding of New Citrus Scion Varieties

Citrus scion breeding produces new potential varieties by hybridization or induction of mutations and then evaluates them at several locations in California. This process is slow because it requires at least two cycles of tree propagation and evaluation. The UCR breeding program, funded by the CRB since 1994, now has a “pipeline” filled with many new selections at various stages of evaluation.
