Scientists have been given permission to grow genetically-modified plants which could help protect against heart disease.
The Department for Environment, Food and Rural Affairs has given the go-ahead for the trial which would see omega-3 fatty acids usually found in fish added to a crop of camelina plants.
It is reportedly the first ever field trial of nutrient enriched crops in the UK.
Scientists at Rothamsted Research Centre in Hertfordshire who will run the trial hailed the decision as a "significant milestone" for research into genetically-modified plants.
Omega-3 has been proven to be beneficial for human health and contribute to protection against coronary heart diseases.
Researchers spent 10 years designing a sustainable way to produce the oil before successfully growing the engineered plants in lab conditions.
The research is part of a project looking in to how seeds could be enhanced to benefit the population's health.
"Being able to carry out the field trial with our GM plants, means that we have reached a significant milestone in the delivery of our research programme" Professor Napier added.
The controlled experiment will start by mid-May with the plants harvested in August or September this year.
A number of seeds from the plants will be used for analysis, while the rest will be destroyed under the conditions of the consent.
The GM inspectorate of the Food and Environment Research Agency will be carrying out regular inspections.
The trial will be funded by the Biotechnology and Biological Sciences Research Council (BBSRC).
