Potter made his request at the first Vegetable Agronomist Association's meeting of 2011 during a speech he gave about "feeding the world".
Discussing the increasing global population, he said: "We will require new skills and new areas of research to be able to feed the growing population and increase home-grown production.
"But I do not think that the industry is doing enough. We do not have enough people in this country standing up to the protesters and championing this issue."
"British scientific research needs to be able to test this technology. We need to leverage the research community and start a greater discussion in support of this technology and start talking to the public about it."
He added: "We have to be in a position as an organisation where we can at least say we have tried these things."
