This illustration traces the process required to generate enough seedling tubers to plant 1 hectare of potatoes from just 20 grams of true potato seed (TPS). The arithmetic involved is as simple as it is elegant. Potato plants produce berries that contain true seeds. One gram of TPS contains 1,000 tiny seeds. Twenty grams of TPS is sufficient to plant a seedbed 100 meters square. This 100-square-meter seedbed produces 30,000 seedling tubers that weigh approximately 500 kilograms, enough to plant 1 hectare. That is a far cry from the 2.5 metric tons of conventional seed tubers required per hectare.
