Wed Mar 10, 2010 7:12pm EST OSLO (Reuters) – A “doomsday” vault storing crop seeds in an Arctic deep freeze is surpassing 500,000 samples to become the most diverse collection of food seeds in history, managers said on Thursday. Set up on the Norwegian archipelago of Svalbard two years ago, the vault aims to store seeds of all food crops deep beneath permafrost to withstand threats ranging from a cataclysmic nuclear war to a mundane power cut. “New seeds … are taking us over the milestone of half a million samples,” Cary Fowler, head of the Global Crop Diversity Trust which runs the vault with the Norwegian government and the Nordic Genetic Resource Center in Sweden, told Reuters. A statement said thousands of new arrivals this week made the vault “the most diverse assemblage of crop diversity ever amassed anywhere in the world.” It overtakes the diversity in a U.S. national gene bank in Fort Collins, Colorado. … The $10 million facility opened in 2008 with 268,000 varieties of seeds from more than 100 countries. The three vault rooms will be able to house 4.5 million samples, or 2 billion seeds since samples usually comprise many seeds, such as of rice, maize, wheat, cowpea or barley. Blasted out of icy rock 1,000 km (600 miles) from the North Pole, the air-locked vaults would stay frozen for 200 years even in the worst-case scenario of global warming and if mechanical refrigeration were to fail, designers say. …
