520			_aScreening for tolerance to abiotic stresses (toxic levels of salt and aluminum, waterlogging, and drought) was conducted in Mexico from 1994 to 1998. The screened materials were elite synthetic hexaploids (Triticum turgidum x Aegilops tauschii) seeded in replicated designs. Wide variation for tolerance was observed in the various synthetics when subjected to different abiotic stresses. Results indicate that the synthetically derived wheats were in most instances significantly superior in abiotic tolerance when compared to their durum progenitors and the tolerant hexaploid checks. This shows that the synthetic amphiploids possess genetic diversity for tolerance to abiotic stresses of the diploid donor species used in their synthesis (given that the durum cultivars were susceptible). The synthetic hexaploids cross readily with T aestivum and offer new genetic variation for abiotic tolerance. Utilization in wheat improvement of this novel source of genetic diversity will be elucidated.
