  1. The iron concentrations in different tissues from mature seeds were obtained by ICP-AES. The iron fraction is the percentage of the total seed iron. The total iron concentration (Total iron) is based on the measured concentrations in the individual tissues. The genotypes with high seed coat iron are from the Mesoamerican (M) gene pool, while the genotypes with low seed coat iron are from Andean (A) gene pools. All the P. vulgaris genotypes were grown in one season in Darien, Colombia. P. coccineus purchased at a market in Denmark shown in Fig. 5 column 1. For some genotypes twoa or threeb individual pools of tissue were measured. N/A: non applicable. Sd: standard deviation.
