AB The genus Citrus, comprising some of the most widely cultivated fruit crops worldwide, includes an uncertain number  of species. Here we describe ten natural citrus species, using genomic, phylogenetic and biogeographic analyses of 60  accessions representing diverse citrus germ plasms, and propose that citrus diversified during the late Miocene epoch  through a rapid southeast Asian radiation that correlates with a marked weakening of the monsoons. A second radiation  enabled by migration across the Wallace line gave rise to the Australian limes in the early Pliocene epoch. Further identification and analyses of hybrids and admixed genomes provides insights into the genealogy of major commercial  cultivars of citrus. Among mandarins and sweet orange, we find an extensive network of relatedness that illuminates the domestication of these groups. Widespread pummelo admixture among these mandarins and its correlation with fruit  size and acidity suggests a plausible role of pummelo introgression in the selection of palatable mandarins. This work  provides a new evolutionary framework for the genus Citrus.
