GENE FLOW AND INTROGRESSION BETWEEN DOMESTICATED CROPS AND THEIR WILD RELATIVES

Roberto Papa

Open publisher page 9 citations

Abstract

Summary Gene flow between crops and their wild relatives is an important process that has strong implications both for conservation of genetic diversity and for plant breeding. Introgression between wild and domesticated populations has been shown to be a widespread phenomenon in most species, both those allogamous and autogamous. The combined effects of gene flow and selection on the structure of genetic diversity of wild and domesticated populations is discussed.
