Figure 2From: Patterns of molecular and phenotypic diversity in pearl millet [Pennisetum glaucum(L.) R. Br.] from West and Central Africa and their relation to geographical and environmental parametersPrincipal component analysis of the 145 pearl millet inbreds examined in our study based on the simple sequence repeat marker allele frequencies. PC1 and PC2 are the first and second principal component, respectively, and the values in brackets give the proportion of explained variance. The different colored segments of the pie charts give the probability that a certain individual belongs to one of the five sub-groups identified by STRUCTURE.Back to article page
