Total seed proteins of 20 Astragalus L. species belonging to 16 sections were electrophoretically analyzed using SDS-PAGE technique. Multivariate analysis (cluster and principal coordinate analysis) of the electrophoretic data showed heterogeneity between some taxa. This heterogeneity was discussed on the light of the controversy over the taxonomic position of Astragalus L. species. The relationships among the examined taxa have been demonstrated as cluster tree using SYSTAT-pc software. This tree illustrated that the studied taxa were separated into two major groups, the New World and the Old World species. The New World group include the species Astragalus wootoni, A. allochrous, A. palmeri, A. layneae, A. lentiginosus, A. nothoxys, A. minthorniae and A. nuttallianu. However, Astragalus coccineus, A. pectinatus and A. didymocarpus that considered from the New World, but separated in the Old World group. Astragalus layneae separated from the rest taxa in the New World group. This species was located in a separate section layneani. The Old World group divided into three subgroups and discussed on the light of earlier classification.
