Resumo: | This study aimed to evaluate the cross-contamination of both conventional soybean seeds with transgenic seeds and transgenic soybean seeds with conventional seeds. The experiment was conducted at the Center of Experimental Stations belonging to the Western Paraná State University, in Marechal Cândido Rondon (Paraná,  Brazil), using the randomized complete block design, with ten varieties of seeds and four replications. The varieties selected were the following: BRS 284 Conventional 1 (seed obtained in Nova Prata do Iguaçu, Paraná); BRS 232 Conventional; BRS 284 Conventional 2 (seed obtained in Marechal Cândido Rondon); BRS 184 Conventional; CD 205 Conventional; Don Mario 7.0i Transgenic; BMX Power Transgenic; BMX Turbo Transgenic; Monsoy 6707 Transgenic and V-Max Transgenic. A total of 1,600 seeds of each variety were sown. Ten days after emergence of the plants, an amount of 2.5 l ha-1 of glyphosate was applied aiming at the differentiation between transgenic and conventional plants, enabling the counting of contaminant plants in each plot. The germination test was performed in the presence of glyphosate, with four subsamples of 50 seeds and three replications each treatment, using as substrate germitest paper previously moistened with distilled water + glyphosate (at a concentration of 1.2 g a. i. L-1) in the amount of 2.5 times the initial weight of the paper. The conventional soybean varieties presented reduced contamination with transgenic seeds. The transgenic soybean varieties presented no contamination with the conventional ones when evaluated in field conditions; however, reduced contamination was verified in the laboratory.
