Interpretive Summary: New citrus scion and rootstock cultivars that improve disease resistance and/or tolerance, meet evolving market demands, enhance flavor, and increase production efficiency are essential for the long term sustainability of the California citrus industry. Potential new cultivars arise through three primary pathways: (1) introductions of commercial cultivars from outside California, (2) discovery of novel types within the state by growers or researchers, and (3) development of new cultivars through citrus breeding programs. This article compiles background information on scion and rootstock varieties recently released from quarantine by the University of California Riverside (UCR) Citrus Clonal Protection Program (CCPP), a Center of the National Clean Plant Network (NCPN). Among the newly released cultivars are eight "Enhanced Germplasm" selections of Australian finger lime.
