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.

省肥、高矿物质含量是小麦保持天然肥料资源和地球环境、为人类提供养分的重要特性。在本研究中，我们通过 ICP 分析仪定量了外源染色体添加小麦品系和初级合成小麦品系中的磷和锌。使用附加系的研究揭示了籽粒和芽中含量之间的相关性，表明在幼苗中进行选择的可能性。在对初级合成小麦的研究中，我们对11种元素进行了分析，发现P、Zn、Fe含量之间存在较高的相关性，用于检查的改良品种的矿物质含量较低，并且矿物质含量与籽粒重量之间的相关性较低。这些研究阐明了野生种质对于小麦改良的有用性。
