At present, China has bred high-quality colored potatoes with mainly purple and red colors. The old varieties of purple and red potatoes have been crossed with excellent and high-yielding potato varieties, and more than 100 colored potatoes of different strains have been improved and screened. Compared with the old varieties, the improved colored potato has small bud eyes, good appearance, and strong disease resistance. The yield per mu can reach 1,000 to 1,500 kg.

The yield per mu is 1500 kg, which is about 20% higher than that of ordinary potato varieties. At the same time, due to the improved disease resistance of this variety, the dosage of pesticides used in the production is greatly reduced, which is beneficial to the production of pollution-free and pollution-free green food.
