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). Entries in the 2018 Arkansas Cotton Variety Test were evaluated in three groups—main transgenic (entries returning from the 2017 test), first-year transgenic, and conventional varieties. The 21 entries in the main transgenic test included 6 B2XF, 3 B3XF, 2 WRF, 8 W3FE, and 2 GLT; the 44 entries in the first-year transgenic test included 8 B2XF, 19 B3XF, 3 GLT, 6 GLTP, and 8 W3FE. The transgenic tests were evaluated at all 5 locations. The conventional test included 15 entries and was 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, 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 2018 report includes results of large-plot variety tests in 7 counties that were coordinated by Bill Robertson.
