The Potato
A Terrific Tuber
The potato is one of the most important food staples of the world. Together with rice, maize, wheat, barley, soy and sugar cane it is one of the seven most important foods on earth. Originally it came from the Andes in South America. The Spaniards brought it to Europe and then to all other continents. It is cultivated in 130 countries on earth. Cultivation has already resulted in many different varieties. Some are waxy, others turn floury when cooked and are especially suited for soups or mash. In Germany, more than a hundred varieties with different qualities and flavours are on the market. Very specific varieties for any purpose are being cultivated. It takes about ten years to develop a new variety and to have it licensed for cultivation. The potato is the most frequent cultivated crop plant and also our staple food. Together with the extensive additional material the DVD is ideally suited for use in the classroom.
