Popis: Changes of frequency at three hordein loci were investigated in Composite Cross Five (CCV) of barley using SDS-PAGE of endosperm proteins. The frequency of individual banding patterns, as well as pattern combinations, showed directional trends in successive generations. This suggests that selection has favoured certain allelic combinations at two hordein loci, Horl and Hor2. We argue that the selective advantage of resistance to powdery mildew, the inbreeding nature of barley, and linkage between some major mildew resistance genes and the hordein loci could have led to the observed shifts.
