Abstract
The endosperm storage proteins of Hordeum chilense Roem. et Schult., a species used in the synthesis of the amphiploid tritordeum (×Tritordeum Ascherson et Graebner), have a great effect on the gluten strength of this amphiploid. We have analysed electrophoretically the heredity of these proteins, which are synthesised by genes located on chromosome 1Hch, and detected up to five loci in a cross between two lines of H. chilense. These loci present a certain homology with loci synthesising the same proteins in wheat. The genetic distances between these loci were calculated.
