Taxonomy of North and Central American diploid wild potato (Solanum sect

Abstract. Solanum section Petota, the potato and its wild relatives, includes about 200 wild species distributed from the southwestern United States to central Argentina and adjacent Chile, with about 30 species in North and Central America. The North/Central American region and the South American region all include diploids, tetraploids, and hexaploids. Chloroplast DNA restriction enzyme data from a prior study showed that 13 of the North/Central American species formed a clade containing only diploids, but there was low resolution within the clade. This Amplified Fragment Length Polymorphism (AFLP) study is conducted to provide additional resolution within the North/Central America
