Abstract: Iron is a necessary mineral element for organisms, it participates in the activities of plant and the composition of matter. Iron content is different in different crop seeds. This article reviewed the research progress on the difference of  iron content in different crop seeds, and the correlation between iron content and agronomic characteristics, which was expected to provide reference for iron fortification research in plant breeding.

Key words: crop, seed, iron content, agronomic characteristics
