Are there any potential adverse environmental consequences of out-crossing from Golden Rice into other rice or weedy relatives?

The introduced trait of provitamin A production in GR2E Golden Rice grains was not intended to alter a specific agronomic characteristic or to confer a fitness (selection) advantage to rice with respect to either abiotic or biotic stressors. Agronomic and phenotypic data collected from confined field tests of GR2E rice conducted at multiple locations in both Bangladesh and the Philippines have confirmed that the characteristics of rice with respect to seedling germination and vigour, plant growth and morphology, reproductive characteristics, and susceptibility to pests and diseases were not altered as an unintended, unexpected, consequence of the genetic modification process.

If the provitamin A trait is transferred by out-crossing from GR2E rice into other cultivated or weedy rice, progeny plants will not exhibit an altered selection advantage that could cause them to become more weedy or invasive in managed or unmanaged ecosystems. There are no anticipated adverse environmental consequences of introgression of the provitamin A trait from GR2E rice into other rice or sexually compatible species.
