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 four University of Arkansas research sites (near Keiser, Judd Hill, Marianna, and Rohwer). All entries in the 2013 Arkansas Cotton Variety Test were evaluated in one group. The 40 entries included 24 entries (12 B2RF, 6 WRF, 3 GLB2, and 3 conventional) returning from the 2012 test and 16 entries (6 B2RF, 9 WRF, and 1 conventional) first-year entries. 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. Entries in both experiments were evaluated for response to tarnished plant bug and bacterial blight in a separate test at Keiser. The 2013 growing season at the north Delta locations differed greatly from locations further south in Arkansas. Due to severe production problems, yield and fiber quality data from the Keiser site are not included with the other locations in this report but are available in the appendix.
