Cotton Variety Selection
The University of Tennessee Cotton Variety Testing Program provides an unbiased evaluation of varieties available for commercial cotton production in Tennessee. The program consists of two major components: The Official Variety Trials, referred to as OVTs, and the County Standard Tests, referred to as CSTs. The OVTs are small plot, replicated variety trials typically located on Research and Education Centers and are composed of major cultivars and experimental strains. The CSTs are large plot variety trials located throughout Western and Central TN and are only composed of major commercial cultivars. Information reported from these trials includes yield, fiber quality data, and Commodity Credit Corporation (CCC) Loan values. Additionally, selected in-season measurements of growth and development are also reported from the OVTs. This program is intended to help cotton producers identify varieties that are high yielding, relatively stable in yield performance across years, and produce high quality fiber; therein, included information should provide those in the seed industry, crop consultants, and the UT Extension service insight into varietal adaptation of all tested varieties to Tennessee field environments.
