    Abstract:

    The different color rice were evaluated based on four mineral concentrations of brown rice from 61 accessions harvested from Mile experiment farm under the uniform ecological conditions by AAS method. The results showed that the Fe, Zn, Cu and Mn concentration of the color rice was higher than that of the write rice, and the four mineral concentrations in brown rice was Zn > Fe > Cu > Mn. In addition, Fe and Zn concentration of color rice were affected by pigment content in pericarp of it, Cu and Mn of color rice were not influenced by pigment content in pericarp of it. Fe concentration of the color rice was in turn black rice>green rice>brown rice>red rice>yellow rice, Zn concentration of the color rice was in turn green rice > red rice > black rice >brown rice >yellow rice, Cu concentration of the color rice was in turn black rice>brown rice >red rice>yellow rice >green rice, Mn concentration of the color rice was in turn brown rice >black rice> red rice>yellow rice >green rice. There were some differences among Fe, Zu, Cu and Mn average concentrations in brown rice of the different color rice, black rice and brown rice rich on Fe, Zn, Cu and Mn, green rice rich on Fe and Zn, red rice rich on Zn and Cu. Four concentration of yellow rice were lower than that of the other color rice.
