Last year, a husband and wife in New Zealand thought they had found a record-breaking potato in their garden. A potato is a round root-like food that is eaten as a vegetable and is popular around the world.

Colin Craig-Brown found the potato with his wife, Donna. They dug it up and put it on a scale. It weighed nearly eight kilograms. They even named the potato “Doug” or “dug” because they “dug it up” from their garden. Doug, the potato, became famous. But then, the two sent some of the potato to the Guinness Book of World Records, based in Britain, to confirm their record.

After months of submitting photos and papers, Colin and Donna recently got some bad news. It turns out what they found in their garden was not a potato, after all. It was a different kind of plant. Guinness said they had found the tuber(块茎) of a gourd(葫芦). “For this reason we do unfortunately have to disqualify the application,” the e-mail from Guinness read. So, the existing record still stands. That potato weighed about five kilograms when it was found in Britain in 2011.

Colin said what he found tasted and looked like a potato. But he was not objecting to Guinness’s decision. After all, he sent them some of it and the organization tested its DNA.

Even though Doug is no longer the world’s largest potato, Colin is still happy to have found such an interesting thing in his garden. Doug is in his freezer. He said he still says “good-day” to Doug each morning when he takes food from the freezer. While he was disappointed with the Guinness decision, Colin said he is ready to give it another try during the next growing season. And this time, it will definitely be a potato.
