THE AMPHIPLOID HORDEUM-CHILENSE X TRITICUM-AESTIVUM - EVALUATION OF ITS GRAIN, FLOUR AND DOUGH CHARACTERISTICS, AND COMPARISON WITH THOSE OF OTHER RELATED CEREALS

The grain, flour and dough quality of the octoploid tritordeum, amphip loid derived from the cross Hordeum chilense Roem. et Schulz. x Tritic um aestivum L em. Thell., were studied in comparison with those of dur um and bread wheats, and hexaploid tritordeum (H. chilense x T turgidu m conv. durum Desf. em. M.K.). Small-scale tests, commonly used for ev aluating quality in cereals, together with the alveograph, were perfor med. Both hexa- and octoploid tritordeum exhibited quality characteris tics similar to those of bread wheat and very different from that duru m wheat. Nevertheless, some genetic differences were found between hex a- and octoploid tritordeum and between the different genetic lines us ed of each one. This genetic variability opens the possibility that bo th hexa- and octoploid tritordeum could be used as new genetic sources in these kind of characters.
