Abstract
Wheat varieties show differential responses to high concentrations of soil boron and genetic studies have shown a single major gene, Bo1, is responsible for the higher level of boron tolerance found in varieties historically dominant in southern Australia. The yield advantage of this gene was evaluated over a range of soil types in southern Australia by comparing boron tolerant and boron intolerant derivatives from a backcrossing program. The advantage of boron tolerant lines ranged up to 11% with an average yield advantage of 3.3% in all trials conducted over a range of soil types. Other evidence suggests this is a conservative estimate of the average yield advantage of the Bo1 gene in this region. Yields of the two groups of lines were not significantly different at sites with soil boron concentrations in the ‘normal’ range.
