Description
Summary:Several studies have indicated that the breadmaking quality of tritordeum (Hordeum chilense-wheat amphiploid) are related with the presence of the H. chilense proteins into the endosperm of the amphiploid. The objective of this work has been to group these proteins by the Osborne's categories and stablish their degree of genetic variation. These protein fractions were obtained from eight lines of tritordeum (5 hexa- and 3 octoploid) and analysed by SDS-PAGE. The results indicated that the H. chilense genome incorporate variable number of protein components to each fraction. Likewise, although the globulin fraction did not presented any variation for the tested lines of tritordeum, a certain degree of variation could be observed in the other three fractions.
