Abstract:Sixteen cotton genotypes with a predominant 'Stoneville' genetic background but various morphological characteristics were grown in the presence of 2 insect populations. Untreated plots yielded an average 170 kg/ha (33%) less lint than insecticide treated plots. Correlations of -0.67 and -0.66 were obtained for lint yield and populations of nymphs of the tarnished plant bug, Lygus lineolaris (Palisot de Beauvais), in the untreated and treated plots, respectively. However, the combination of the nectariless trait and traits related to earliness gave acceptable yields in both untreated and treated plots. The addition of the nectariless trait to glabrous and frego bract traits resulted in reduced populations of tarnished plant bug nymphs.
