  abstract = {{Q}uinoa ({C}henopodium quinoa {W}illd.) is a pseudocereal originated from the {A}ndes important for small farmers' food security as well as for commercial production. {R}ecently, it has been claimed that in {B}olivia genetic erosion could result from the marginalization of the crop in the north and from its commercial standardization in the south. {T}he aim of this study was to quantify the hierarchical structure of the genetic variation present in eight quinoa field populations, consisting of cultivated and weedy individuals, representative of the altiplano and interandean valleys of {B}olivia. {R}andomly amplified polymorphic {DNA} markers show that quinoa has a strong population structure and a high intra-population variation. {A}n effect of geographical structure of the populations was highlighted, due to population isolation, not simply linked to distance but more probably to climatic and orographic barriers present in the studied zone. {T}he population structure is also reinforced by the limited seed exchanges among farmers as revealed by field interviews. {T}his population structure appears related to three major biogeographic zones: the northern and central altiplano, the interandean valley, and the southern {S}alar. {I}ntrapopulation genetic diversity was higher than that expected for a mainly autogamous species, and higher than that reported in anterior studies based on germ.plasm collections. {T}hese results are commented in view of current knowledge on phylogeny and reproductive biology of the species, and their implications regarding genetic resources management are discussed.},
