520 _aPsathyrostachys juncea (2n = 2x = 14, NN), a source of barley yellow dwarf luteovirus (BYDV) resistance with tolerance to drought and salinity, was successfully hybridized in its autotetraploid form (2n = 4x = 28, NNNN) as the pollen parent to durum wheat (Triticum turgidum [T. durum]). The 2n = 4x = 28 (ABNN) F1 hybrid has a mean meiotic metaphase I configuration of 20.29 univalents + 0.29 ring bivalents + 3.36 rod bivalents + 0.14 trivalents. Spike length, internode length, glume awn length and lemma awn length, as well as the general spike morphology of the F1 hybrid, are intermediate with those of the 2 parents. Pollinating the ABNN F1 hybrid gave backcross (BC1) derivatives of an amphiploid (AABBNN) that expresses limited self-fertility. BC2 derivatives were obtained from these plants. Direct transfers of useful genes from P. juncea to wheat would require substantial genetic manipulation strategies. Both conventional and novel methodologies, which may complement each other, and so facilitate reaching an agricultural objective end point, are addressed
