To determine whether increased expression of HMW (high-molecular weight) glutenin genes in wheat endosperm can result in improved baking quality of hard winter wheat, and if such approaches can confer greater environmental stability of quality, and to determine if there are any negative effects of transgenic expression on agronomic properties.
To develop and characterize adapted waxy (amylase-free) and partial waxy wheats, and to exploit the waxy gene system to produce novel wheat starches.
To identify and characterize new sources of resistance to preharvest sprouting, and sources of low or nil grain polyphenol oxidase.
To coordinate the Hard Winter Wheat Improvement Program and supervise the Hard Winter Wheat Regional Performance Nursery Program.
