The total seed protein of 16 accessions of Amaranth us hybridus (Amaranths) from the NIHORT germplasm were investigated by SDS- polyacrylamide gel electrophoresis. The result of the electrophoresis indicate that the seed proteins of the Amaranthus are heterogeneous and they composed of 54 polypeptide bands with apparent molecular weight of 2 to 106 kilodaltons. The result showed that there was only one band common to all accessions and the accessions could not be separated by seed colour on the basis of staining intensities and presence/absence of bands. Accessions with the same seed colour had a higher similarity index indicating a closer relationship when compared to seeds with different colour. SDS-polyacrylamide gel electrophoresis is a valuable tool in classifying the Amaranth germplasm and the genetic and evolutionary relationships among the accessions could be determined based on similarity indices
