摘要

Aegilops spp. were collected in Morocco and identified as mainly Aegilops ovata and Ae. triuncidlis, as well as some Ae. ventricosa and Ae. triaristata. These Aegilops spp. along with other collections, were screened for resistance to Hessian fly. Some Ae. ovata accessions were highly resistant. In terspecific crosses with Ae. ovata and Ae. triuncialis and also with Agropyron spp. were performed. The result was genotypic and sometimes even plant specific. Hybrids and backcross progenies were cytologically examined. Anther culture, already successfully used for bread wheat and barley, and intergeneric crosses with maize, are being used to fix karyotypes.
