Abstract: | This review discusses a multidisciplinary and multicomponent approach leading to the development and commercial release of
transgenic Costa Rican rice varieties tolerant to the herbicide gluphosinate ammonium. We describe the field evaluations of
the transgenic lines and their potential environmental impact, focusing on gene flow, particularly in relation to native wild
Oryza species and weedy rice, based on trials performed in compliance with the national regulatory requirements of the country.
We also present a socio-economic analysis of rice production in Costa Rica and the economic benefits of genetically modified
(GM) rice as well as an environmental risk-benefit analysis for the deployment of GM rice. Additionally, food safety evaluation,
intellectual property management, requirements for deregulation, and options for the commercialization of the new varieties
are discussed. We also present results from a national survey aimed at assessing the level of support for GM crops in Costa
Rica as this forms an integral component of our approach. Taken together, our results demonstrate that the adoption of these
genetically improved rice varieties will provide clear benefits to Costa Rican rice growers and consumers. |
