Genetical and Breeding Studies on alien chromosome addition and synthetic wheat lines showing fertilizer saving

节约肥料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性，也是小麦为人类提供营养的重要特征。利用电感耦合等离子体光谱仪对异附加系和人工合成系的磷、锌含量进行了测定。利用附加系的研究表明，籽粒和地上部的含量之间存在相关性，这表明在幼苗中进行选择的可能性。以初级合成小麦为材料，分析了11种元素含量，发现P、Zn、Fe元素含量之间有较高的相关性，改良品种作为对照，其矿质元素含量较低，矿质元素含量与粒重之间的相关性较低。这些研究阐明了野生种质对小麦改良的有用性。

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.
