Abstract

Golden mosaic is among the most economically important diseases that severely reduce bean production in Latin America. In 2011, a transgenic bean event named Embrapa 5.1 (EMB-PV051-1), resistant to bean golden mosaic virus, was approved for commercial release in Brazil. The aim of this study was to measure and evaluate the nutritional components of the beans, as well as the anti-nutrient levels in the primary transgenic line and its derived near-isogenic lines after crosses and backcrosses with two commercial cultivars. Nutritional assessment of transgenic crops used for human consumption is an important aspect of safety evaluations. Results demonstrated that the transgenic bean event, cultivated under field conditions, was substantially equivalent to that of the non-transgenic bean plants. In addition, the amounts of the nutritional components are within the range of values observed for several bean commercial varieties grown across a range of environments and seasons.
