dc.description.abstractChromosome 7Hch from Hordeum chilense has potential for improving seed carotenoid content in wheat as it carries a Phytoene synthase 1 (Psy1) gene, which has a major role in this trait. Structural changes in chromosome 7Hch were obtained in common wheat background by crossing the wheat disomic substitution line 7Hch(7D) with a disomic addition line carrying chromosome 2Cc from Aegilops cylindrica in common wheat cv. ‘Chinese Spring’. Rearranged 7Hch chromosomes were cytologically characterized by FISH. A set of 24 molecular markers and the Psy1 gene were used to identify the H. chilense chromosome segments involved in the introgressions. Six structural rearrangements of chromosome 7Hch were identified. They included three homozygous wheat–H. chilense centromeric translocations, one involving the 7HchS arm (T-7HchS·A/B) and two involving the 7HchL arm (T1-7HchL·A/B and T2-7HchL·A/B). In addition, one 7HchS arm deletion, one 7HchL·7HchL isochromosome and one 7HchS telosome were obtained in hemizygous condition. These genetic stocks will be useful for studying the effect of chromosome 7Hch on wheat flour colour.es_ES
