摘要：

AFLP markers were used to assess genetic diversity and patterns of geographic variation among 39 accessions of foxtail millet (Setaria italica) and 22 accessions of green foxtail millet (S. viridis), its putative wild progenitor. A high level of polymorphism was revealed. Dendrograms based on Nei and Li distances from a neighbour joining procedure were constructed using 160 polymorphic bands. Bootstrap values revealed that no specific geographic structure can be extracted from these data. The high level of diversity among Chinese accessions was consistent with the hypothesis of a centre of domestication in China. The results also showed that accessions from Eastern Europe and Africa form two distinct clusters. The narrow genetic basis of these two gene pools may be the result of local-adaptation.
