Bread Wheat Biofortification for Grain Carotenoid Content by Inter-Specific Breeding.

ABSTRACT: Bread wheat has traditionally been selected for whitish derived flours. As a consequence, the current varieties carry carotenogenic alleles associated with low grain carotenoid. In contrast, high grain yellow pigment content (YPC) has been a major target in durum wheat programs since yellow colour is an important aesthetic factor for pasta production. Phytoene synthase 1 (Psy1) genes have an important role in the determination of the carotenoid content in wheat. In this work, we have transferred the genes Psy1-A1 and Psy1-B1 from durum to bread wheat by inter-specific hybridization in order to evaluate the combined effect of these genes for the improvement of grain carotenoid content, as well as the development of carotenoid-enriched bread wheat lines.
