About Potatoes

Introduction

Potato (Solanum tuberosum L.,) is one of the important culinary vegetable belongs to family Solanaceae, which is comprises of about 2000 species. Out of which, only two tuber bearing species viz Solanum tuberosum and Solanum andigenum have been commercially exploited throughout the world. Solanum tuberosum is widely cultivated in large scale. It is a native of Andes mountains of South America (Peru) from where it spreads all over the world.

Potato plants are herbaceous perennials with leaves that die back after flowering, fruiting and tuber formation. They have flowers that are white, pink, red, blue or purple with yellow stamens. In general, potatoes are classified into a few major groups based on common characteristics, such as russet (rough brown skin), red, white and yellow (also known as Yukon) and purple potatoes.

The Potatos Global Legacy as King of Vegetable

The potato, cultivated in over 100 countries with more than 4,000 edible varieties, with a global harvested area of 16.8 million hectares, producing 383 million metric tons and achieving a productivity of approximately 22.8 metric tons per hectare. It is a globally cherished staple and the world’s 4th most important food crop after rice, wheat and maize. This nutritious and easily digestible food is rich in carbohydrates, vitamins (like C&B6), proteins, minerals and dietary fiber, and contains health-promoting phytochemicals such as carotenoids, flavonoids and caffeic acid.
