Fertilizer saving and high mineral contents are the important traits to keep natural fertilizer resource and global environment and also to provide nutrients to human being through wheat. In this study we quantified phosphorus and zinc in alien chromosome addition wheat lines and primary synthetic wheat lines by ICP analyzer. The study using the addition line revealed correlation between the contents in kernels and in shoot, suggesting possibility of selection in young seedlings. In the study using the primary synthetics wheat, we analyzed 11 elements and found that there is high correlation among P, Zn and Fe contents, that improved cultivars used as checks contain low minerals, and that there is low correlation between the mineral contents and the kernel weight. These studies elucidated usefulness of wild germplasm for wheat improvement.
