Figure 1.

Plot of first two principal components from an analysis of 17 phenotypic traits on 374 diploid alfalfa (Medicago sativa L.) genotypes. Individual genotypes are coded as belonging to one of five populations on the basis of molecular-marker clustering conducted previously (Sakiroglu et al., 2010).
