Conteúdo: 	Selection for aluminium tolerance is necessary to adapt the soya bean crop to vast areas of acid soil in the tropics such as the Brazilian Savannas (Cerrados). The breeding programmes include field testing of large numbers of varieties. The tests are laborious, time consuming and need to be repeated to minimize effects of uncontrolled environmental fators. The present results show that augmented designs are efficient in the identification of Al-tolerant genotypes. These designs (i) allow elimination of soil differences as common causes for error in comparison of entries, and (ii) can be successfully employed in genetic studies and breeding programmes for crop improvement, being more cost effective than fully replicated trials.
