beans offer the advantage of reducing insecticides that have being used to kill the whiteflies that transmit the golden mosaic virus during the past decades. The new virus resistant beans are also considered as safe for consumption as the currently cultivated beans. On that ground, CTNBio, the multidisciplinary commission responsible for making science-based, technical assessments for the safety of genetically engineered products approved the beans for commercial release.
Approvals by CTNBio may be followed by an examination from the National Biosafety Council (CNBS) on the socio-economic convenience and opportunities of national interest.
There are in any case, further steps to be pursued on the way to market the seeds, such as the incorporation of the trait into cultivars suited to the different local conditions, the registration of the variety and production of the seeds. The following step is the law inspired by the UPOV Convention (International Union for the Protection of New Varieties of Plants), legislation that came with the intend of protecting the rights of developers of plant varieties, no matter if obtained through conventional breeding or modern biotechnology, while encouraging investment in research and development. According to the legislation, any plant variety with a minimum of clearly new distinguishable characteristics goes through a process to be registered. After the approval of registration the new variety enters the fields of seed production. Farmers will probably have to wait another 2 to 3 years to see the virus-resistant beans.
