Genetic diversity (Watterson's θ [37]) for seven neutral genes (N), 13 putative domestication genes (D), and 14 putative improvement genes (I) sampled from wild (Wild), landrace (Land) and improved (Imp) sunflower populations.

Six previously analysed genes are indicated by ¶. P-values are given for the results of the ML-HKA test for each candidate gene in each of the three populations. * Significant at P≤0.1,**P≤0.05. Comparisons that remained significant after false discovery rate correction are indicated in bold (FDR <0.05) and underlined (0.05< FDR <0.1).
