Summary

F1 hybrids of dlfferent varletles of T. durum and T. aestivum with the amphldlploid T. durum/Agr. elongatum as well as a trigenerlc hybrid combining the genomes of T. durum, Agr. elongatum and Dasypyrum villosum were obtained.The crossing ability and viabillty of hybrid seeds, the percentage of obtalned hybrid plants and their fertility which showed a genotypic dependence were determined. The sterility of the trigeneric hybrid was overcome by backcrosslng with one of the parents. A cytological analysis in Ml and in diakinesis of F1 hybrids of T. durum and of the trigenerlc hybrid was carried out and the possibillty, although small, for the involvement In homeologous pairing of V and E chromosomes in a wheat medium was established.
