Abstract

Many Mediterranean crop plants contain a large fraction of the genetic diversity possessed by their wild relatives. Bottlenecks during domestication commonly cause the loss of genetic variation in these species, and reductions in diversity are much greater in annuals than in perennials, for which the loss of variation may be moderate or even null. The process of domestication likely occurred in a multilocal fashion over a wide area stretching from the Fertile Crescent to the Mediterranean and central Asia. However, gene ...
