Abstract

The primary goal of the Arkansas Cotton Variety Tests 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 Division of Agriculture research sites (Manila, Keiser, Judd Hill, Marianna, and Rohwer). The tests at Rohwer were abandoned due to undefined herbicide injury. The 2025 tests at Keiser were adversely affected by excessive early rain which delayed planting. Yields from the Keiser transgenic test are not reported and are not included in over location means. Entries in the 2025 Arkansas Cotton Variety Test were evaluated into two groups–transgenic and conventional varieties. The 42 entries in the transgenic test included 5 B3XF, 14 B3TXF, 11 W3FE and 12 AXTP lines, which were evaluated at all five locations. Only 4 of 14 varieties having ThryvOn® technology (B3TXF) were evaluated in both the 2024 and 2025 Arkansas Cotton Variety Tests. The conventional test included 11 entries and 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 bugs and bacterial blight in separate tests at Keiser. This 2025 report includes results of large-plot variety tests in 7 counties that were coordinated by Zachary Treadway.
