Abstract

Although the garden tomato is very highly self-polli nated in most regions of cultivation, it is cross-pollinated at much higher rates in the range of its wild relatives— Ecuador, Peru, and northern Chile. Cohabitation of garden tomatoes and an intercompatible species in this region permits extensive gene exchange between them. These factors lead to a high level of variability and promote rapid evolution of new forms.

Additional information

Part of the information submitted here was collected in South America during the tenure of a John Simon Guggenheim Memorial Fellowship (1948–49). Additional studies on a second trip in 1956–57 were partly supported by research grant No. GA-AGR-5547 from the Rockefeller Foundation. The privilege of such support is gratefully acknowledged. It is also a pleasure to express appreciation for the help of many friends in South America, the list of whose names would fill several pages.
