在小麦中，类胡萝卜素对于面条生产的最终使用质量非常重要。六倍体三倍体是源自野生二倍体大麦（Hordeum chilense）和硬粒小麦杂交的双倍体。六倍体三托小麦比其各自的小麦亲本表现出更高的类胡萝卜素含量。使用 H. chilense 的 H1 和 H7 品系之间的杂交来绘制类胡萝卜素含量的数量性状基因座 (QTL)。多重区间作图确定了一个定位在 2 号染色体上的 QTL。由于 H. chilense 与小麦族其他成员的高度杂交性，这一知识有助于将这一有利性状转移到其他谷物基因组中。
In wheat, carotenoids are very important for end-use quality in noodle production. Hexaploid tritordeums are the amphiploids derived from the cross between a wild diploid barley (Hordeum chilense) and durum wheat. Hexaploid tritordeums exhibit a higher carotenoid content than their respective wheat parents. The cross between H1 and H7 lines of H. chilense was used in order to map quantitative trait loci (QTL) for carotenoid content. Multiple interval mapping identified one QTL mapped on chromosome 2. This knowledge is helpful to transfer this favourable trait to other cereal genomes because of the high crossability of H. chilense with other members of the tribe Triticeae.
