Table 2. Analyses of Molecular Variance (AMOVA) of Diatraea saccharalis populations based on the 1,331 SNP markers.
The analysis considered different host-plant species and geographic regions. φ statistics are indices of the amount of differentiation among populations, similar to Wright’s F statistics. d.f. = degrees of freedom.
