摘要

A review of available historical and scientific evidence on the origin of the first European populations of the potato late blight pathogen P. infestans, is given. It is suggested that the current theories of a direct introduction into Europe and North America from either a Mexican or an Andean centre of origin and of diversity are questionable. An alternative theory, involving a 3-step process; (1) migration from central Mexico to South America several centuries ago, (2) migration from South America to the USA in 1841-1842 and (3) migration to Europe from either South America, USA or both, in 1843-1844, is suggested. It is concluded that this theory agrees with historical records and with the genetics and structure of current populations.
