Wheat Varieties Grown in Cooperative Plot and Nursery Experiments
in the Spring Wheat Region in 1989
Hard Spring Wheat Results Coordinated and Compiled by:

and G. Linkert, Junior Scientist
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
