Abstract
For breeding to increase amylose content in the starch of hexaploid wheat, either the introduction of genes from Aegilops squarrosa (DD genome) or the development of high-amylose amphiploids between Triticum durum (AABB genome) and Ae. squarrosa is one of the most efficient ways. The high-amylose genes have not been detected in any species of Triticum and Aegilops. Therefore, we assessed the apparent amylose content in endosperm starch of T. durum and Ae. squarrosa accessions supplied from the major gene banks from world wide, and found several accessions with higher amylose content out of 665 T. durum accessions and out of 732 Ae. squarrosa accessions. Genetic analysis indicated that a high amylose trait in Ae. squarrosa is monogenically inherited by a recessive major gene.
