Title	Chromosomal location of genes for carotenoid pigments in Hordeum chilense
Journal	Plant Breeding
Year	2004
Volume	123
Pages	303-304
Author	Atienza SG Ramirez CM Hernandez P Martin A
Abstract	Summary: 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
