Abstract

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 2021 tests at Rohwer were abandoned due to excessive rain and flooding occurring on 8–9 June. Entries in the 2021 Arkansas Cotton Variety Test were evaluated in two groups—transgenic and conventional varieties. The 44 entries in the transgenic test included 3 B2XF, 30 B3XF, 10 W3FE, and 1 GLTP line, which were evaluated at all five locations. The conventional test included 16 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 2021 report includes results of large-plot variety tests in 7 counties that were coordinated by Bill Robertson.
