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...
Although boron (B) is a micronutrient essential for the growth of vascular plants, it reduces growth and seed yield when present in excessive amounts. A hydroponic assay of nineteen Brassica rapa genotypes resulted in the identification of two tolerant genotypes, WWY Sarson and Local at a range of boron concentrations (15–165 µM). The most tolerant and sensitive genotypes were assessed for shoot boron...
