Seed proteins from 226 accessions of Stylosanthes (mostly S. hamata) were examined electrophoretically, providing 27 esterase bands from the single enzyme substrate alpha-naphthylacetate. The accessions came from 23 geographical areas, and an inter-area distance matrix was obtained from the isozyme data. The resulting network delineated the geographical relationships almost as clearly as that from morphological/agronomic data. The relations between isozyme bands and morphological/agronomic attributes were explored by an "inverse" network procedure; it is shown that the bands are not only standing in lieu of morphological atrtributes, but may sometimes recover independent information of an unknown nature.
