对26个小麦品种6个立地x年组合中生物活性成分（工具、甾醇、烷基间苯二酚、叶酸、酚酸和纤维成分）含量的分析表明，各成分因品种和环境的差异程度显著。其总黄酮含量、甾醇含量和阿拉伯木聚糖纤维含量具有较高的遗传性，是植物育种的理想目标。然而，在籽粒发育过程中，生物活性成分的含量与环境因子（降水和温度）之间也存在显著的相关性，甚至在不同年份、不同地点生长的籽粒样品中，高遗传成分的含量也存在差异。
Analysis of the contents of bioactive components (tocols, sterols, alkylresorcinols, folates, phenolic acids, and fiber components) in 26 wheat cultivars grown in six site x year combinations showed that the extent of variation due to variety and environment differed significantly between components. The total contents of tocols, sterols, and arabinoxylan fiber were highly heritable and hence an appropriate target for plant breeding. However, significant correlations between the contents of bioactive components and environmental factors (precipitation and temperature) during grain development also occurred, with even highly heritable components differing in amount between grain samples grown in different years on different sites.
