Sweetpotato is a member of the family Convolvulaceae, Genus Ipomoea, section Batatas. It is the only hexaploid (6x = 90) in this section. Section Batatas continues toundergo revision but contains approximately 12 other species, most of which are diploid (2n = 30), with a few tetraploids (4x = 60) collected in the wild (Bohac et al., 1993). Jarret et al. (1992) supported a hypothesis that Ipomoea trifida (H.B.K.) G. Don and wild Mexican tetraploids are putative ancestors of the cultivated sweetpotato.
