- Abstract
Landraces of tetraploid and hexaploid wheat front the Northern Negev in Israel were evaluated over two years for their grain quality attributes. Twenty- one population of tetraploid wheat (Triticum durum, represented by 56 accessions) and 8 populations of hexaploid wheat (T. aestivum and T. compactum, represented by 13 accessions) were compared with 3 and 4 modern improved Israeli cultivars of tetraploid and hexaploid wheat, respectively. This comparison allowed to estimate the progress made in the improvement of grain quality in present-day cultivars. Except for grain protein content in the hexaploids, significant variation was revealed among landraces in kernel weight, protein content (tetraploids), sedimentation, mixograph score and carotin content. The best modern cultivars were comparable to the best landraces in kernel weight and carotin content (tetraploids), indicating that modern wheat breeding maximized kernel weight and carotin content, as compared with the tested landraces. Grain protein content and/or quality was not maximized in modem cultivars and its improvement was deemed possible by introgression from the best landraces in this respect.
