The potato plant belongs to the Solanaceae family and the Solanum genus. Potato is one of the most
important crops in the world and is the fourth most produced crop in the world after corn, wheat
and rice. This crop accounts for the highest production in Iran after wheat, sugarcane, tomatoes and
alfalfa. This plant is considered a long-day plant in terms of flowering and a short-day plant in terms of tuber

as well as potato nutrition.
