[The genetic analysis of Al-tolerance in maize].

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.
