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.

肥料储蓄和高矿物质是保持自然肥料资源和全球环境，并通过小麦为人类提供营养的重要特征。在这项研究中，我们通过ICP分析仪在外来染色体添加小麦系和原发性合成小麦系中定量磷和锌。使用加法线的研究表明，内核中的内容物与芽中的内容之间的相关性，这表明在幼苗中选择的可能性。在使用主要合成小麦的研究中，我们分析了11个元素，并发现P，Zn和Fe含量之间存在很高的相关性，这些元素的改善了用作检查的品种含有低矿物质，并且矿物质含量与核心重量之间的相关性较低。这些研究阐明了野生种质对小麦改善的有用性。
