Twenty three selected lines originated from population submitted to gamma irradiation (27.5 krad), in the F4 generation, from the interespecific hybrid between BH-1146 (Triticum aestivum L.) and Anhinga "S" x Winged "S" (Triticum durum L.) and the check cultivars BH 1146 and Yavaros "S" (T durum L.) were evaluated in nine trials, named "New Varieties 111". Evaluation trials were carried out at different locations under upland and sprinkler irrigation conditions, for grain yield, yield components and disease resistance. In laboratory conditions, the germplasms were evaluated for their Al toxicity tolerance in nutrient solutions. The lines 11, 12, 13 and 14 presenting semidwarf plant type, moderate lodging resistance, medium cycle from emergence to flowering and tolerance to aluminum toxicity showed higher productivity in the average of nine experiments. Yavaros "S" and the lines 8 and 12 showed at the same time immune to the causal agent of leaf rust and moderate resistance to the causal agent of mildew, in adult stage. All analysed genotypes were susceptible to the causal agent of leaf spots. The lines 3, 9 and 10 showed to be good genetic sources for long spike; the line 12 for large number of spikelets per spike; the lines 12, 13 and 14 for large number of grains per spike; Yavaros "S" for higher number of grains por spikelet; and the lines 1, 2, 3, 4, 6, 7, 10 and 15, and Yavaros "S", for high grain weight. All of them were tolerant to aluminum toxicity excepting Yavaros "S" and the lines 9 and 15 which exhibited high sensibility.
