The primary goal of the Arkansas Cotton Variety Test is to provide unbiased data regarding the agronomic performance of cotton varieties and advanced breeding lines in the major cotton-growing areas of Arkansas. This information helps seed companies establish marketing strategies and assists producers in choosing varieties to plant. These annual evaluations will then facilitate the inclusion of new, improved genetic material in Arkansas cotton production. Adaptation of varieties is determined by evaluating the lines at five University of Arkansas System Division of Agriculture research sites (Manila, Keiser, Judd Hill, Marianna, and Rohwer). The 2022 tests at Rohwer were adversely affected by herbicides. The tests were replanted but did not achieve acceptable maturity. Yields from Rohwer are reported but not included in the overall location means. Entries in the 2022 Arkansas Cotton Variety Test were evaluated in two groups—transgenic and conventional varieties. The 40 entries in the transgenic test included 1 B2XF, 27 B3XF, 11 W3FE, and 1 GLTP line, which were evaluated at all five locations. The conventional test included 20 entries, which were evaluated at all locations except Manila. Reported data include lint yield, lint percentage, plant height, percent open bolls, yield component variables, fiber properties, leaf pubescence, stem pubescence, and bract trichome density. All entries in the experiments were evaluated for response to tarnished plant bug and bacterial blight in separate tests at Keiser. This 2022 report includes results of large-plot variety tests in 7 counties that were coordinated by Bill Robertson.
