The influence of variety and growing location on the carotenoid and vitamin E content of 184 different varieties of durum wheat of each of the German locations Hohenheim and Seligenstadt was analyzed by HPLC. In addition, the yellow pigment content was measured as b value using a chroma meter. The results showed that the measured parameters vary both between sites and varieties, with higher variance between varieties. Finally, we elaborated a high genetic variance and heritability for lutein and total carotenoids and no negative correlations to important agronomic and quality traits in durum wheat. Thus, future durum breeding could produce varieties with improved agronomy, quality, and increased contents of lutein and total carotenoids. Vitamin E has only a minor importance due to the low contents in durum wheat. Due to the high correlation between the b value and the total carotenoid content, the b value could be used as a cheap and rapid method to initially screen high numbers of breeding lines before testing individual promising breeding lines with HPLC, warranting efficient and accurate selection of durum lines with increased carotenoid content.

品种和生长地点对德国184种硬质小麦（Trictic turgidum ssp。durum）类胡萝卜素和维生素E含量的影响

通过HPLC分析了德国霍恩海姆和塞利根施塔特每个地点的184个硬粒小麦品种的品种和生长地点对类胡萝卜素和维生素E含量的影响。另外，黄色颜料含量以b表示。使用色度计的值。结果表明，实测参数在位点和品种之间均存在差异，品种间差异较大。最后，我们阐述了叶黄素和总类胡萝卜素的高遗传变异性和遗传力，与硬粒小麦重要的农艺和品质性状没有负相关。因此，未来的硬粒小麦育种可以生产出具有改进的农艺学，品质以及叶黄素和总类胡萝卜素含量增加的品种。由于硬粒小麦中的维生素E含量较低，因此维生素E仅具有次要的重要性。由于b值与总类胡萝卜素含量之间的高度相关性，因此b 值可作为一种廉价，快速的方法，用于在通过HPLC测试单个有前途的育种系之前初步筛选大量育种系，从而确保高效，准确地选择具有增加类胡萝卜素含量的硬质小麦。
