This paper reviews the results of studies on the physiological control of tolerance to high concentrations of B. These studies were initiated following the identification of high levels of B in the subsoil throughout southern Australia to facilitate the breeding of B tolerant varieties. Genetic variation in response to B has been identified for the major crop and pasture species of South Australia, including lines more tolerant than any Australian varieties of wheat, barley, pasture medics, and peas. There is the potential for improving the level of B tolerance of local varieties. The apparently similar mechanism controlling B tolerance for all species suggests relatively simple genetic control also exists for species other than wheat
