VARIATION FOR BREADMAKING QUALITY CHARACTERS IN SEVERAL CROSSES OF HEXAPLOID TRITORDEUM-NIXTRITORDEUM ASCHERSON ET GRAEBNER) WITH A COMMON PARENT

The grain, flour and dough quality of several crosses of hexaploid tri tordeum, amphiploid derived from the cross Hordeum chilense Roem. et S chulz. x Triticum turgidum conv. durum Desf. em. M.K., were studied al ong with their common tritordeum parent. Small-scale tests, commonly u sed for evaluating quality in cereals, together with the alveograph, w ere performed. In general, the hexaploid tritordeum exhibited quality characteristics similar to those of bread wheat and very different of durum wheat. Nevertheless, some genetics differences were found betwee n the crosses used in this work. H. chilense seems to be the cause of the most of these differences. Furthermore, because the wide range of variation for some quality characters in the small sample of tritordeu ms investigated in this study, it seems feasible the attainment of goo d quality tritordeum, using the broad collection of new synthesized tr itordeums and well-established breeding procedures.
