Abstract: This study evaluated the reaction of soybean genotypes (conventional and transgenic) to cercospora leaf blight (Cercospora kikuchii). Two experiments in a completely randomized block design with three replications were carried out (Cristalina GO and Brasília DF, Brazil) during the crop period of 2005/2006. In the experiment 1, 86 non-transgenic genotypes were evaluated, while in the experiment 2, 30 transgenic (RR) and non-transgenic genotypes were tested. For comparisons purposes the following genotypes were used: conventional Emgopa 313 and Msoy 8001, and transgenic Msoy 8585 RR and Msoy 8787 RR. The genotypes with lower levels of disease incidence (<1%) were: experiment 1 - GT04-7229, GT04-8987, GT04-8902, GT04-7991, GT04-8218, GT04-9501, GT04-7020, GT04-7505 and GT04-7439; experiment 2 - GT04-7437 RR, GT04-9192 RR, GT04-8091 RR, GT04-8203, GT04-9265 RR and GT04-9085 RR. There was no significant difference in disease intensity between transgenic and non-transgenic genotypes and the Cercospora leaf blight intensity reported in this study was low when considering lesions on leaf area (< 1.5%) and disease incidence (< 20%).
