Hard white wheat is a value-added product that is of great intrest to the milling industry because white wheat offers significant processing advantages over red wheat.  These advantages include higher milling extraction as well as white wheat whole baked goods free of the bownish coloured bran and stringent taste associated with red wheat.  In certain export markets, white wheat is preferred over red wheat so hard white wheat affers opportunities to access new markets.  However, the development of white wheat presents new challenges to researchers,  one of the most important being that white wheat is more susceptible to preharvest sprouting.  Production of white wheat in higher rainfall production areas like Manitoba will require varieties with superior preharvest sprouting resistance.

This project will address the problem of preharvest sprouting resistance in two ways:

1.   The identification of new white seeded sources of preharvest sprouting resistance for use in the Cereal Research Centre hard white wheat breeding program.

2.   The development of molecular markers for preharvest sprouting resistance that can be used in hard white wheat development.
