520 _aConcerns regarding possible associations between plant height and A1 tolerance in wheat (Triticum aestivum L. em Thell) led to this investigation. Standard height, low grain yield potential, A1 tolerant cultivars ‘BH 1146’ and ‘Atlas 66’ and semidwarf, high grain yield potential, A1 sensitive cultivars ‘Tordo’ and ‘Siete Cerros’ were crossed in a diallel fashion. Parents, F1's, F2's and reciprocal backcrosses were tested for their seedling reaction to 6 ppm of A1. Plant height and grain yield were determined for the same populations at maturity. Parent-progeny regression estimates for A1 tolerance and plant height were high (b = 0.903) but intermediate (b = 0.507) for grain yield. Genotypic, phenotypic and environmental correlations, between A1 tolerance with plant height and grain yield, respectively, were not significant. Grain yield and plant height correlations ranged from 0.274 to 0.813 and were significant (P = 0.01). Results suggest it would be possible to select plant types which combine A1 tolerance and semidwarf height levels; however, large F2 populations will be required. Tordo appears to be the most promising dwarfing source for the development of semidwarf cultivars adapted to soils with high A1, but poor seed quality could be a limiting factor using this source of germplasm.
