The inheritance of tolerance to high concentrations of boron in Brassica rapa was studied in F2 and F3 segregating populations. The F1 hybrids were produced from genotypes contrasting in their reaction to boron. The F1 hybrids responded similarly to the tolerant parent indicating that boron tolerance was dominant trait. Segregation patterns for boron tolerance in F2 populations and F3 derived families were established by the measurements of primary root length and tissue boron concentrations. The segregation ratios were explained in terms of two major genes interacting in a dominant epistatic manner to govern tolerance. Evaluation of selected tolerant and susceptible F3 families indicated that tolerant families produced significantly longer primary roots as compared to susceptible families.
