The aluminium tolerance of 31 varieties within 11 species in six genera of the Cruciferae was determined by measuring root length under aluminium stress. Variance analysis indicated highly significant differences of aluminium tolerance among the species compared. Raphanus sativus (2 n = 18, RR) had the highest aluminium tolerance, followed by Brassica carinata (2 n = 34, BBCC), Brassica oleracea (2 n = 18°C) and Brassica napus (2 n = 38, AACC), which had the C genome. There might be more than one gene for aluminium tolerance in the R and C genomes. Those species such as Brassica campestris (2 n = 20, AA), Brassica nigra (2 n = 16, BB), Brassica juncea (2 n = 36, AABB), Arabidopsis thaliana (2 n = 10, arar), Sinapis alba (2 n = 24, alal), Cheiranthus cheiri (2 n = 12, chch) and Orychophragmus violaceus (2 n = 24, OO) that did not include the R or C genome had lower aluminium tolerances. Transfer of aluminium tolerance from R. sativus into the cultivated brassicas seems possible by intergeneric hybridization and the production of addition, substitution or translocation lines.
