Potatoes are divided into purple, red, black, yellow potatoes, colorful potatoes and so on. China has cultivated high-quality colored potatoes with purple and red as the main colors. By crossing the old varieties of purple and red potatoes with excellent high-yield potato varieties, more than 100 copies of colored potatoes with different strains were improved and screened.

Compared with the old varieties, the improved colored potatoes have small buds, beautiful appearance and strong disease resistance, and the yield per mu can reach 1000 to 1500 kg. Colored potatoes can also be developed as special foods.
