**International Symposium on Increasing Wheat Yield Potential**

***Challenges to Wheat Production Internationally***

CIMMYT, Obregon, Mexico

March 20-24th, 2006

The International Maize and Wheat Improvement Centre will convene a
Symposium on increasing wheat yield potential in high production zones,
with emphasis on the developing world. Presentations will cover the
latest technologies in breeding, genetics, physiology and crop
management that can be applied to maximize genetic yield potential and
its expression. Other presentations and discussion will focus on how
technologies can be applied to increase and stabilize farm yields with
an emphasis on improving food security and livelihoods. Participants
will include wheat scientists globally, including representatives from
the largest and highest yielding production zones in the world.
