In a set of 3 experiments, a number of parental lines and various of their hybrid and backcross generations (from crosses of tolerant and sensitive lines) were raised in nutrient solution containing 195 umol Al/litre. An analysis of relative seminal root lengths showed than additive gene effects contributed most to genetic variation in Al tolerance, with dominance effects accounting for only half as much varation. Epistatic effects were minor. The frequency distributions of tolerance in the F2 were typical of a quantitatively inherited trait. There was a tendency for non-tolerance to be dominant over tolerance although this was not consistent. Analysis of the F1 from a diallel cross among 8 inbred lines indicated that general combining ability variance explained most of the variation, but specific combining ability effects were significant in each case. |
