Crops are often subjected to iron(Fe)-deficiency
due to the limited solubility of this essential element in most neutral or
basic soils. Developing cultivars with high efficiency in Fe utilization via
breeding programs can provide solutions to this problem as a long term
strategy. In the present study, to select inbred lines for breeding of maize
with high efficiency in Fe utilization, we screened 123 inbred lines at the
seedling stage by analyzing secretion pattern of phytosiderophores, a class of
non-protein amino acids released by graminaceous species for Fe utilization,
using high-performance liquid chromatography. One hundred and twenty three
inbred lines were clustered into nine groups. The low PS secretion rate under
Fe-sufficient condition and high PS secretion rate increment after
Fe-deficiency treatment type were the ideal inbred lines for breeding of maize
with high efficiency in Fe utilization.
