A new high-protein amphiploid wheat was compared to its diploid (Triticum tauschii biotype strangulata) and tetraploid (T. turgidum var. dicoccoides) progenitors and to a commercially grown hexaploid hard red winter wheat (T. aestivum cv. Newton) all grown under the same conditions. The comparisons included light and transmission electron microscopy, quantitative image analysis, and polyacrylamide gel electrophoresis of extracted prolamines. The amphiploid was found to possess endosperm characteristics of both the progenitors as revealed by various microscopic techniques. Polyacrylamide gel electrophoresis of gliadins showed that the amphiploid contained the same bands as both its progenitors.
