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, amphiploid derived from the cross Hordeum chilense Roem. et Schulz. x Triticum aestivum L em. Thell., were studied in comparison with those of durum and bread wheats, and hexaploid tritordeum (H. chilense x T turgidum conv. durum Desf. em. M.K.). Small-scale tests, commonly used for evaluating quality in cereals, together with the alveograph, were performed. Both hexa- and octoploid tritordeum exhibited quality characteristics similar to those of bread wheat and very different from that durum wheat. Nevertheless, some genetic differences were found between hexa- and octoploid tritordeum and between the different genetic lines used of each one. This genetic variability opens the possibility that both hexa- and octoploid tritordeum could be used as new genetic sources in these kind of characters.
