%X The heredity of Al-tolerance was studied in different Al-tolerance of two inbred lines of maize and their F1, F2, B1 and B2 generations by the means of nutritional cultivation. The results indicated that the relative biomass (Al/CK) of root had high hereditary variance, the broad-sense heredity reached 78.6 %, but narrow-sense heredity only had 15.4 %. Its hereditary pattern mainly was dominant effects. On contrast, the relative biomass of shoot had high narrow-sense heredity (43.1%), it means that the hereditary pattern of relative biomass of shoot mainly was additive effects. On the hereditary ground of 0.1 mmol/L Al(3+), the broad-sense heredity of total absorbing surface to volume ratio and active absorbing surface to volume ratio were 17.9 % and 36.4 %, and narrow-sense heredity of them were 10.0 % and 18.4 %. It means that the characters of root activity were obviously affected by environment.
