The origin of the potato

Posted by TopVeg - June 7th, 2008

The international year of the potato is witnessing an Andean war of words over where exactly the potato originated.

Peru and Chile have each been laying claim to the origin of the potato, but now Bolivia have entered the fray.

Chile dispute the bulk of scientific evidence — and the UN potato website — suggesting the potato was first cultivated near Lake Titicaca in southern Peru. Chile claim the potato first grew on Chile’s southern Chiloe Island, citing DNA tests showing that almost all the 7,000 potato varieties in the Netherlands have Chilean origins. The Chileans say the studies show that more than 90 percent of modern potato varieties outside the Andes have a common origin in potatoes once found in the area around Chiloé Island, in southern Chile.

Peruvian potato experts point to genetic studies showing that all potatoes currently eaten in the world originated more than 10,000 years ago from a single ancestor, Solanum brevicaule, found on the north shore of Lake Titicaca. That would be on the Peruvian side, not in Bolivia.

Bolivia do not agree. They say they have evidence that the potato originated on their side of Lake Titicaca. The origin of the potato is in dispute!

Posted by TopVeg - May 31st, 2008

potato-leavesThe vegetable gardener should inspect the potato leaves daily to look for potato blight.

Potatoes are growing very quickly in the warm damp weather. These warm, damp conditions are the ideal environment for potato blight.

Early potatoes are relatively safe because they can be eaten before the potato blight does any damage.

Start to Ridge up Potatoes

Posted by TopVeg - May 5th, 2008

The potatoes have started to grow as the temperature rises, and it is easy to start to ridge them up as they grow. The potato seed was planted shallowly, just covered with soil, so that it would come out quickly. When the shoots are about 12 cm above the ground, the base of the stalk is covered with soil. It does not matter if one or two of the bottom leaves are covered with soil, but the main shoot must remain uncovered.
