采用电感耦合等离子体原子发射光谱法（ICP-AES）分析了29个韩国小麦品种的8种重要矿物质（Cu、Fe、Mn、Zn、Ca、K、Mg和P）含量。应用系统聚类分析方法对具有相似性的小麦品种进行了分类。微量元素Cu、Fe、Mn、Zn的含量范围分别为0.12~0.71 mg/100 g、2.89~5.89 mg/100 g、1.65~4.48 mg/100 g、2.58~6.68 mg/100 g。常量矿物质Ca、K、Mg、P的含量范围分别为31.3~46.3 mg/100 g、288.2~383.3 mg/100 g、113.6~168.6 mg/100 g、286.2~416.5 mg/100 g。HCA将所有小麦样品分为6个簇，各组的矿物质组成存在显着差异。在6个集群中，第二组是高的铁和钙，而第四组有高的铜，锰和钾的浓度，第五集群是高的锌，镁和磷。在韩国小麦品种的矿物成分的变化，可用于小麦育种计划，以开发一个新的小麦品种具有高矿物质含量，从而改善小麦籽粒的营养状况。
Twenty-nine Korean wheat cultivars were analyzed for 8 important minerals (Cu, Fe, Mn, Zn, Ca, K, Mg and P) using Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). A hierarchical cluster analysis (HCA) was applied to classify wheat cultivars, which has a similarity in mineral compositions. The concentration ranges of the micro-minerals Cu, Fe, Mn, and Zn: 0.12~0.71 mg/100 g, 2.89~5.89 mg/100 g, 1.65~4.48 mg/100 g, and 2.58~6.68 mg/100 g, respectively. The content ranges of the macro-minerals Ca, K, Mg and P: 31.3~46.3 mg/100 g, 288.2~383.3 mg/100 g, 113.6~168.6 mg/100 g, and 286.2~416.5 mg/100 g, respectively. The HCA grouped 6 clusters from all wheat samples and a significant variance was observed in the mineral composition of each group. Among the 6 clusters, the second group was high in Fe and Ca, whereas the fourth group had high Cu, Mn and K concentrations; the fifth cluster was high in Zn, Mg and P. The variation in mineral compositions in Korean wheat cultivars can be used in the wheat breeding program to develop a new wheat cultivar with high mineral content, thus to improve the nutritional profile of wheat grains.
