df indicates the degree of freedom, SS sum of squares, MS mean sum of squares, σ² the estimated component of variance attributable to each factor and Φ the estimation of the genetic differentiation.. * P < 0.050, ** P < 0.010; *** P < 0.001.
Analysis of Molecular Variance (AMOVA) in both, the wild and the domesticated populations. Two hierarchical levels were analyzed in the wild populations: country level (regions, R), population level (S) and only one level, the population level (S), was analyzed in domesticated populations.
