Technical Abstract: Plant germplasm is living material, capable of being propagated, that contains genetic information that is passed down through time. Plant germplasm is the basis for plant agriculture and improvement. Citrus is a fruit crop of major importance in areas with a climate suitable for its growth. It has spread from its center of origin in southern and eastern Asia into other parts of the world. Citrus germplasm, as generally conceived, also includes taxa in the related 32 genera of the subfamily Aurantioideae of the family Rutaceae. These genera are mainly native to the same area as citrus but have limited economic uses. Their major importance may be in the genes that they can contribute citrus improvement programs. This book chapter provides an overview of citrus genetic resources and their utilization. The subfamily Aurantioideae is reviewed and updated from the classic treatment of Swingle (1943). The status of in situ and ex situ conservation efforts for citrus germplasm around the world is summarized. Utilization of citrus genetic resources involves acquisition, introduction, maintenance, and evaluation. These facets of the management of citrus germplasm resources are reviewed with special emphases on phytosanitary issues and biotechnological techniques.
