Spuds in the spotlight at the Esplanade
A display of New Zealand potato cultivars features in the Victoria Esplanade in Palmerston North this summer in
recognition of the United Nations declaration of 2008 as the International Year of the Potato.
The display, opposite the paddling pool, is the initiative of Crop & Food Research which has joined with the Palmerston North City Council and Horticulture New Zealand to reveal there is
much science to the vegetable that 97% of New Zealanders eat and 54% of us dine on four or more times a week.
The display of 11 cultivars was planted by Crop & Food Research staff in early November and is being tended by Palmerston North City Council staff. It is an opportunity
for people to see a range of potatoes plants including those that produce tubers for the fresh market, crisping and
chipping.
Palmerston North Mayor Jono Naylor says “We’re delighted our Esplanade can be used to highlight potatoes and to help
Crop & Food Research and Horticulture NZ with increasing the awareness of the humble spud. We’re proud of what Crop & Food Research and Horticulture NZ achieves in this community and their international reputations are thoroughly
deserved.”
Julian Heyes of Crop & Food Research says his Crown Research Institute is unique in the world in the diversity of its involvement with
potatoes.
“Our scientists are deciphering the DNA code of potatoes, developing improved crop management systems, breeding potatoes
with elite characteristics, supporting production of Taewa or Māori potatoes, gaining a better understanding of the
nutritional benefits of potatoes and developing healthy convenient potato-based products,” he says.
Lucy Lesperance, who leads a Crop & Food Research nutrition team says there is good reason why some people refer to potatoes as a nutritional jewel box.
“They are rich in carbohydrates, making them a good source of energy, and they have vitamin C, other antioxidants,
potassium and are high in protein,” says Dr Lesperance. “Also, potatoes are low in sodium, sugar and fat, and when not
cooked in oil or fat are not fattening.”
Dr Heyes says one of the projects in the Future Vegetable research programme aims to develop potatoes and processes that
reduce the amount of fat absorbed during cooking.
“One day we should enjoy hot chips without feeling guilty about the fat we’re eating,” he says. “Also, we are looking
at ways of lowering the Glycaemic Index of potatoes so when we eat potatoes their energy is released in a more sustained
way making us feel fuller for longer.”
Dr Heyes says there is potential to breed potatoes with enhanced levels of nutrients and phytochemicals and to select
those with greater health benefits.
Crop & Food Research works closely with growers, through Horticulture NZ Potato Product Group, as well as food processors,
manufacturers and exporters.
Terry Olsen who grows potatoes at Opiki and chairs the Horticulture NZ Potato Product Group says in declaring 2008 the
International Year of the Potato the United Nations General Assembly recognises the need to increase awareness of the
potato’s role in improving food security and poverty alleviation in developing nations.
It is significant that the world population is projected to grow by around 100 million people a year over the next two
decades, 95 percent in the developing world.
Potato crops require little input and notably need considerably less water than either rice or pasta wheats to grow a
similar serving size.
Mr Olsen says in New Zealand potatoes are the country’s most important and valuable vegetable export crop – worth over
$90 million in 2007.
Potatoes are grown in all parts of the country with around 500,000 tonnes, or 3 billion, tubers produced annually.
Sales of the New Zealand staple top $300 million annually.
Mr Olsen says the potato industry’s investment in research is critical to future market growth.
“The innovations that come from research and smart partnerships will provide consumers with fresh potatoes and potato
products that look and taste good, are healthy and, importantly, are sustainably produced,” he says. “Crop & Food Research regularly introduces its latest developments to potatoes and those who eat them and grow them are
benefiting.”
Crop & Food Research and Horticulture NZ are planning a public harvest of the potatoes in late March/early April.
