| Abstract: | Hexaploid tritordeum is the amphiploid derived from the cross between Hordeum chilense and durum wheat. The storage proteins synthesised by the Hch genome have an influence on the gluten strength of this amphiploid. The D-prolamins of H. chilense are glutenin-like proteins. The variability has been analysed electrophoretically and up to 20 different patterns have been detected in a world collection of this species. This genetic variability of H. chilense could be a source of additional variation in tritordeum and in breeding wheat for quality. Received: 29 November 1998 / Accepted: 19 December 1998 |
