Black potatoes successfully cultivated in Heilongjiang Province

The potatoes people see in daily life are all yellow or white, but now a kind of black potato has been successfully cultivated in Mudanjiang City, Heilongjiang Province. This potato is black-purple in appearance, with an oblong tuber shape and deep purple flesh. Its starch content is higher than that of ordinary potatoes, and its texture is more "mealy" than ordinary potatoes. Li Hongxing, a senior agronomist at the Mudanjiang City Vegetable Science Research Institute, said that this potato took 4 years to cultivate successfully, and through successive years of generation-advancing cultivation, 0.4 hectares have been cultivated so far. Last autumn, the harvest reached 8,500 kilograms, and starting this year it can be promoted on a large scale.

According to preliminary analysis by agricultural experts, the reason this potato appears black-purple is that it contains a large amount of anthocyanins, and anthocyanins have an anti-aging effect on the human body. This potato has the characteristics of a well-developed main stem, few branches, strong growth vigor and strong disease resistance, with a yield of 1,500 kilograms per 667 sq m, about 20% higher than ordinary potato varieties. At the same time, because of the improved disease resistance of this variety, the dosage of pesticides used in production is greatly reduced, which is conducive to producing pollution-free, hazard-free green food.
