Eighteen dihaploid wheat lines originated via anther culture from F1 hybrid plants and control cultivars Al Res 102/84 and IAC-24 were evaluated for grain yield, yield components, agronomic characteristics and resistance to leaf rust, in four field trials performed under upland and sprinkler irrigation conditions. The genotypes were evaluated for their tolerance to Al toxicity, in nutrient solutions, in laboratory conditions. The dihaploid line 5, originated from the cross IAS 63/ALDAN "S"//GLEN/3/IAC-24, exhibited dwarf plant type, lodging and leaf rust resistance and tolerance to Al toxicity allied to high productivity. Line 6 was considered a good genetic source for large number of grains per spikelet, dwarf plant type, resistance to lodging and leaf rust, whereas line 8, for long spikes and large number of spikelets per spike. All of them were tolerant to aluminum toxicity except IAC-287 (sensitive control).
