Steven B Johnson PhD is a crops specialist and extension professor with the University of Maine in the United States. We asked him what it takes to grow the perfect potato and what the chances of genetic modification would be.

Is Genetic Modification a viable option for potato production: are there benefits in terms of nutrition, yield?

GM potatoes are a viable option for potato production. Modifications to the nutritional value of the potatoes are certainly a possibility. Reducing pesticide use and protecting the stored crop are great opportunities for GM potatoes. Consumer acceptance is key to the future of GM potatoes.

How enthusiastic are producers and processors in terms of new ideas, for example Ethylene?

As a rule, I find producers and processors are eager to try new approaches. However, they run the economic numbers to the new approaches after feasibility studies have been performed and evaluated. Both groups are in business and regularly assume risk but neither want undo risk.

Steve, do you agree that it is necessary for the links between producers (growers) and processors to be strong, to ensure optimal use of the product?

Yes, I do. If links aren’t strong, neither does well. While there are times the relationship is tense, producers and processors need each other and have to work together.

What are your current research projects?

I am investigating temperature and humidity variations within potato storages, several potato-pathogen interactions, different approaches for sampling of field populations of pests. We are also working on several computer modelling applications.

From country to country, are there marked industry differences in terms of research and development?

From my experience, yes.

If so, what are they?

The link between some industries and academic workers appears to be stronger in Europe that in the US.

Is there much international cooperation in relation to research and development between countries?

There are some notable US projects but really not enough of them. European countries tend to be more advanced in this aspect that the US.

The potato sits close to the top in terms of being a global food crop. Do you foresee the potato strengthening its position; particularly in developing countries?

Yes I do. The potato is highly adaptable and produces well under many environments. Potatoes are widely grown in developing countries. Adoption of GM in some instances may produce and protect more produced food.

In your opinion, are there any current issues producers and processors need to address?

Food safety is an ever increasing concern.

How do you prefer eating the humble spud?

It has to be mashed with milk and butter and whipped with a blender. I have been known to eat chips and crisps as well!
