Conteúdo: | In order to evaluate the gene flow from the transgenic soybean RR (Round Up ready) to non-transgenic soybean, an experiment was conducted in Embrapa Cerrados (Federal District, Brazil). Plots with non-transgenic plants, were sowed around a central plot with the transgenic soybean plants (Var. Conquista, line BR00-69515), transformed with the cp4 epsps gene, which confers glifosate resistance. The plots were previously identified and the seeds of each plot were separately harvested, counted and sowed to evaluate the resistant plants containing the cp4 epsps gene. Plants were sprayed at the third-trifoliate stage with the herbicide glifosate (Round Up) at 2,4 Kg.ha-1. Plants that survived were analyzed by PCR. The percentage of natural cross was calculated as the fraction of tolerant plants from the total number of plants. The frequency of cross-pollination between the transgenic line BR 00-69515 and non-transgenic plants were 0,485% (at 1 meter from the central plot). The frequency of cross pollination was dramatically reduced at 2 m from the central plot (0,099 %), and reduced to 0.063%, 0.054 %, 0.021 %, 0.019 %, 0.020 %, 0.009 %, 0.006 % e 0.005 % in each subsequent meter, up to 10 m of the central plot.
