Choosing a cotton variety involves making comparisons over many trials and across an increasingly large number of available varieties. To aid in this process, a computerized tool has been developed at the University of Arkansas. This tool, called COTVAR, allows multiple comparisons of varieties across a number of trial locations. COTVAR uses cotton OVT data to make comparisons that are entered by the user.

Currently, the database includes only Mid-South Official Variety Trials (OVTs). These OVTs were conducted in Arkansas, Louisiana, Mississippi, Missouri, and Tennessee. It is planned to include other geographies in the future.
