Pesquisa Agropecuaria Brasileira v. 22, no. 3, p. 257-263617560Summary: A study of 13 populations and of 5 populations together with their F1 crosses and reciprocals, grown in nutrient solution containing 222 æM Al/litre, showed that relative seedling root length (initial length/length after 8 days) gave good discrimination between genotypes while top dry weight and root dry weight did not. The experimental hybrid CMS200 and the populations CMS30 and CMS36, which had been selected in soils with aluminium toxicity, were tolerant when grown in the nutrient containing Al. The crosses showed no reciprocal differences in tolerance. Additive variance was predominant. CMS36 and CM30 had a positive effect for tolerance (on
