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.

节肥和高矿物质含量是保持天然肥料资源和全球环境的重要特征，也是通过小麦为人类提供养分的重要特征。本研究利用电感耦合等离子体分析仪对外源染色体附加小麦品系和初级合成小麦品系中的磷和锌进行了定量研究。利用附加系进行的研究表明，籽粒和地上部的含量之间存在相关性，这表明在幼苗期进行选择是可能的。在以初级合成小麦为材料的研究中，对11种元素进行了分析，发现磷、锌、铁含量之间相关性较高，作为对照的良种矿质元素含量较低，矿质元素含量与粒重的相关性较低。这些研究阐明了野生种质在小麦改良中的作用。
