摘要：
Hordeum chilense Roem. et Schult. is a native South American diploid wild barley included in the section Anisolepis Nevski. H. chilense occurs exclusively in Chile and Argentina and has been used in the synthesis of a new amphiploid named tritordeum (xTritordeum Ascherson et Graebner). The HMW glutenin subunits of H. chilense have a great influence on gluten strength of tritordeum. The variability of these proteins has been analysed electrophoretically, and up to ten allelic variants have been detected in a world collection of this species. This genetic variability has been included in 121 lines of tritordeum and could be used for widening the genetic basis of tritordeum and wheat.
