N, number of genotypes; SD, standard deviation.

Multilocus LD significance: ^*P = 0.01, ^**P < 0.01.

^†Mesoamerican wild (subclusters MW_1, MW_2, MW_3), Mesoamerican domesticated (subclusters MD_1, MD_2, MD_3), Andean wild (subclusters AW_1, AW_2, AW_3), Andean domesticated (subclusters AD_1, AD_2, AD_3).
