A number of plant measurements were evaluated for their ability to differentiate genotypes for Al tolerance in nutrient solution culture. The best traits proved to be seminal and adventitious root lengths. On this basis, Brazilian inbred lines were shown to be more tolernat of Al than those from the USA. In most lines, root lengths decreased as the Al concentrations used, but in some Brazilian lines root length was unaffected. Al tolerance increased if P was included in the nutrient solution. The combination of 185 umol P/litre in the nutrient solution was the best for evaluationg genotypes for Al tolerance.
