Beyond semi-dwarf wheat yield increases: impacts on the Australian wheat industry of on-going spillovers from the International Maize and Wheat Improvement Center

Abstract

Wheat genetic materials developed from research at the International Maize and Wheat Improvement Center (CIMMYT) in Mexico for developing countries have provided spillover benefits to Australia. Varieties developed from those genetic materials have resulted in yield increases in Australia. While the initial impact came through the introduction of higher-yielding semi-dwarf wheat crops, those impacts have continued in the post-semidwarf period. CIMMYT’s success in developing countries has also reduced the world price for wheat. While the lower prices affect returns in Australia, the increased yields in Australia from the CIMMYT spillovers from both the semi-dwarfs and the postsemidwarf phases have provided benefits to Australia averaging A $30 million per year.
