Abstract
Triploid hybrid embryos (AABB x SS = ABS) were produced by crossing two moderately salt-tolerant wheats, namely Triticum turgidum durum and Aegilops speltoides subsp. speltoides. The embryos were rescued by culturing on agar No. 1. Chromosome doubling was achieved by using 0.05% colchicine. The resulting hexaploid plants grew to maturity, and produced a considerable amount of seed (approximate to 40,000). The synthetic hexaploid (C-2) was tested for salinity tolerance, grown at 0, 100, 125, 150, 160, 170, 180 and 200 mM NaCl in a standard nutrient solution for 2 weeks. The criterion of salt tolerance was root growth in different NaCl concentrations. The amphidiploid material showed greater salinity tolerance than either parent, suggesting the presence of different genes for tolerance in the parents.
