Abstract
Slab gel electrophoresis techniques have been applied to the study of isozyme and kernel protein patterns in 20 accessions ofHordeum chilense and related species in order to elucidate their phylogenetic relationships. On the basis of our results we can conclude that: (1) Conventional classification based on morphological characters does not totally agree with biochemical data. (2) Sectt.Anisolepis andCritesion seem to be clearly differentiated. (3) The accessions classified asH. compressum present biochemical phenotypes quite different from the rest of the species. (4)H. stenostachys, H. muticum andH. chilense constitute a group of variable species with many biochemical similarities and close phylogenetic relationships. (5) The evolutionary pattern of these American species seems to follow a model of reticulate evolution.
