The anther injury index technique to determine relative susceptibility to tarnished plant bugs was found to be simple, rapid and consistent during a recent evaluation of rolled bract (Frego) cottons. A concerted regional effort to increase the level of plant bug resistance in rolled bract cotton was initiated in 1976. Two such cultivars, Arkansas Frego #25 and Louisiana Frego #560, repeatedly gave competitive yield in these regional trials. In 1983, a detailed evaluation of these two advanced rolled bract cottons was initiated in Arkansas. All work was done in small plots (2 rows, each 30 ft long). The basic experimental design was a split plot with main plots or blocks being insect control with appropriate insecticides to control insects vs no insect control. Subplots consisted of the following cultivars: Arkansas Frego #25; Louisiana Frego #560 Nectariless; Arkugo #4 Normal bracted, fast fruiting; Stoneville 213 Normal bracted, standard deltatype; and Stoneville 825 Normal bracted, nectariless. Planting was completed May 20 in 1983 and May 25 in 1984.
