Are synthetic hexaploids a means of increasing grain element concentrations in wheat?

In a world where there is arguably enough food produced and many gains have been made in increasing wheat production, Calderini and Ortiz-Monasterio have evaluated wheat varieties for their suitability for breeding to increase essential micronutrients. Specifically the research examines parameters such as grain yield, nutrient input use, and whether better distribution of nutrients in the edible portions of grains is possible. -- from Text
