 STATE AGRICULTURAL EXPERIMENT STATIONS
 
 Wheat Varieties Grown in Cooperative Plot
 and Nursery Experiments in the Spring Wheat Region in 1990
 
 Hard Spring Wheat Results Coordinated and Compiled by:

 This is a joint progress report of cooperative investigations underway in the State 
 Agricultural Experiment Stations and the Agricultural Research Service of the U.S. 
 Department of Agriculture containing preliminary data which have not been sufficiently 
 confirmed to justify general release; interpretations may be modified with additional 
 experimentation. Confirmed results will be published through established channels. The 
 report is primarily a tool for use of cooperators and their official staffs and for those 
 persons having direct and special interest in the development of agricultural research 
 programs.
 
 This report includes data furnished by the State Agricultural Experiment Stations as well as 
 by the Agricultural Research Service U.S. Department of Agriculture. This report is not 
 intended for publication and should not be referred to in literature citations nor quoted in
