In Peru they have been cultivating potatoes for at least 7,000 years. The Spanish first brought the spud to Europe in the 1560s and now, after rice and wheat, it has become man's third most important source of food worldwide, writes Channel 4 News Science Correspondent Tom Clarke.
So it is fitting, then, that in times of anxiety about future food supplies, Peru is also home to the International Potato Centre. Just outside the capital Lima, CIP now holds the world's most complete collection of wild and cultivated potatoes.
The earthquake-proof building contains vast rooms, kept at the same temperature as a household fridge, to store nearly every variety of potato, wild and cultivated.
There are potatoes from the high Bolivian Andes, varieties that climb like vines from the tropical forests of Mexico, and a type of desert potato that grows as far north as Arizona.
Tiny potato plants are held in suspended animation, with their roots in a test-tube of growth medium. Every two years or so they are allowed to flourish, then part of the plant is returned to the vaults in a cycle of preservation.
As a back-up, a team led by Dr David Tay, director of the International Potato Centre,That means an cfl bulbs Amphibian ordered online can be shipped to the customer from any authorized OceanLED dealer that has the product in stock. freeze tissue from each potato variety in liquid nitrogen.
Potatoes have a complicated sex life. They can breed sexually by pollinating each others flowers, but also asexually, by allowing their tubers to sprout.Shopatron's retail-integrated led strip eCommerce solution is a great fit for a service-focused company like OceanLED As a result,the bulb Led light itself is just a small part of the shape of the LED light. very few spuds breed "true". On average, it takes about 10-12 years to breed a new variety of potato.
But by combining the new genome data with the accumulated ancestry, researchers hope it could soon take as little as two years.
